May Weather in Moroni

Long-run averages for May

85°F (29°C) High Temp
70°F (21°C) Low Temp
10.1 inches (257 mm) Rainfall
83% Humidity
10 Sunny-Day UV
⚠ Afternoon tropical downpours can drop 30-50 mm (1.2-2 inches) in under an hour, flooding unpaved roads and turning laterite trails into mudslides. Plan all outdoor excursions for the morning and avoid mountain roads after early afternoon. Start early. ⚠ Malaria is endemic in Comoros year-round, and May's residual standing water from the wet season keeps mosquito populations high. Consult a travel health clinic at least four weeks before departure for prophylaxis. This is not optional. Get pills. ⚠ The monsoon transition in May can produce confused swells and strong currents along the volcanic coastline. Do not swim at unprotected sites without local advice, and check sea conditions before any inter-island ferry crossing. Rough seas cause seasickness on these small vessels even in experienced sailors. Be warned.

Is May Right for You?

Weigh the advantages and considerations before booking

Advantages
  • + Ylang-ylang flowering season opens in May. The distilleries scattered along Grande Comore's coastal roads fire their wood-burning stills for the first time since the rains. The scent carries on the wind for hundreds of metres, thick, sweet, almost narcotic, and you'll smell it before you see the corrugated-iron sheds where workers spread freshly picked star-shaped blossoms across woven mats. Few visitors ever witness this harvest. Plantation owners are generally happy to walk you through the steam-distillation process if you show up early.
  • + Sea turtle nesting season begins along Moheli's southern beaches in May. Female green turtles haul themselves onto the sand after dark, dig their body-pit nests by moonlight, and lay clutches of over a hundred eggs before dragging back to the surf. The marine park at Itsamia runs guided night watches. You sit on the dark beach, hear the heavy rasp of a turtle's flippers on wet sand, and wait. This is one of the Indian Ocean's last places where this happens on an unmanaged, unfenced shoreline with no entrance queue.
  • + Eid al-Adha, called Ide el-Kabir locally, is expected to fall around May 16 or 17 in 2027. In a country where 98 percent of the population is Muslim, the celebration transforms Moroni completely. Families slaughter a sheep or goat and divide the meat into thirds: one for the household, one for neighbours, one for the poor. The Badjanani Mosque overflows at dawn prayer. The air fills with woodsmoke and roasting meat by mid-morning, and strangers are routinely invited inside homes to eat. If you are present, you are included. There is nothing performative about it.
  • + Moroni in May is essentially yours alone. Comoros receives a tiny fraction of the visitor numbers that reach neighbouring Madagascar or the Seychelles, and within that already thin stream, May sits outside the July-August diaspora-return season and well before the September-November dry-season window that the handful of dive operators promote. You will not queue for anything. You will not see another tourist at Volo Volo Market. The medina's carved-door workshops, the waterfront where fishermen mend nets on black volcanic rock, the call to prayer echoing off coral-stone walls at dusk, all of it develops at the pace of a city that is not performing for an audience.
Considerations
  • − May still sits in the tail of the wet season, and 257 mm (10.1 inches) of rainfall is not a drizzle. Afternoon downpours hit fast and hard. The sky turns pewter around 1 PM, the rain arrives in sheets that flood unpaved streets within minutes, and the red laterite trails on Mount Karthala become slick clay. Mornings are usually clear and gorgeous. Plan outdoor excursions for the first half of the day. Accept that some afternoons will be spent under a corrugated roof listening to rain hammer the tin.
  • − Inter-island transport between Grande Comore, Moheli, and Anjouan is unreliable in the best of months, and May's monsoon transition makes it worse. The small propeller planes that connect the islands cancel without warning when crosswinds exceed their limits, and the motorised ferries are slow, sometimes rough, and occasionally just do not run. Getting to Moheli's turtle beaches requires either a 45-minute flight or a multi-hour sea crossing. Build at least one buffer day into any island-hopping plan. The cancellation is likely, not merely possible.
  • − Humpback whales do not arrive in Comorian waters until July, and the peak whale-watching window runs through September. If swimming alongside a forty-tonne cetacean in open water is the reason you are coming to the Indian Ocean, May puts you six weeks too early. The underwater visibility is also still recovering from wet-season runoff. Divers will find 10-15 metre (33-49 ft) visibility rather than the 25-30 metres (82-98 ft) that August and September deliver.

Best Activities in May

Top things to do during your visit

Mount Karthala Crater Trek

Karthala is the reason Grande Comore exists. This active shield volcano rises 2,361 metres (7,746 ft) from the sea and holds one of the largest active craters on earth, roughly 8 km (5 miles) in circumference. The standard ascent starts from the village of M'Vouni on the western flank, climbs through dense montane forest where the air is cool and damp and smells of wet moss and decomposing leaf litter, then emerges above the treeline into a landscape of grey volcanic scree and sulphur-stained rock. The crater rim, when you reach it, drops away into a vast bowl of solidified lava flows streaked yellow and white. In May, the morning clarity can be extraordinary. You might see all the way to Moheli on the southern horizon before the afternoon clouds build. The trade-off is mud. The trails through the forest belt are soaked from the receding rains, and every step above 1,500 metres (4,921 ft) needs to be planted with care. Book through a licensed guide at least two weeks ahead. Carry at least three litres of water per person. Start before dawn. The round trip covers roughly 15 km (9.3 miles) with 700 metres (2,297 ft) of elevation gain and takes 8 to 10 hours as a day hike, or you can camp overnight at the crater rim if the weather cooperates. See current guided options in the booking section below.

Booking Tip: Arrange your guide and 4x4 transfer at least two weeks before your intended summit day. May weather is unpredictable above the treeline, so ask for a flexible rebooking policy in case cloud cover or rain forces a postponement. Confirm that the operator provides a satellite phone or radio. There is no mobile signal above the forest belt. Check current guided trek availability in the booking widget below.
Moheli Marine Park Sea Turtle Night Watch

Moheli, the smallest and least developed of the three main Comorian islands, protects its southern coastline as a marine park, and May marks the opening weeks of the green turtle nesting season. The experience is deliberately low-tech: you fly or ferry from Moroni, settle into one of the handful of community-run guesthouses near Itsamia or Nioumachoua, and after dark a park warden leads you down to a beach lit only by stars. The sand is still warm from the day's heat under your bare feet, the surf hisses against volcanic rock at the edges, and somewhere in the darkness you hear the laboured scraping of a 150-kilogram (330 lb) turtle dragging herself above the tideline. You watch from a respectful distance, no torches, no flash photography, as she digs, lays, covers, and returns to the water. The whole process takes over an hour. In May the nesting is just beginning, so encounters are less guaranteed than in the July-August peak. But the beaches are emptier and the wardens have time to explain what you are seeing. Snorkelling the reef flats during the day is a bonus. The volcanic drop-offs host reef sharks, octopus, and clouds of anthias in water that is still a warm 27 degrees C (81 degrees F).

Booking Tip: Book your Moheli flights as early as possible. There are only a few departures per week from Moroni, and the small aircraft fill quickly. Build one extra day into your Moheli stay to absorb the cancellation that weather or mechanical issues will likely cause. Confirm turtle-watch availability with the marine park community office on arrival, as nesting is weather-dependent. See current Moheli excursion options in the booking section below.
Moroni Medina and Volo Volo Market Dawn Walk

Moroni's medina is not a museum piece or a restored heritage zone. It is a working neighbourhood where families live behind carved wooden doors set into coral-stone walls that have stood since the fifteenth century. The lanes are narrow enough that you can touch both sides with outstretched arms, the light filters down in slats between overhanging balconies, and the air carries a rotating cast of smells: roasting coffee from a doorway kitchen, the salt-and-iodine tang of drying fish, the sweetness of ripe jackfruit stacked against a wall. The Badjanani Mosque, built in 1427 with its minaret added five centuries later in 1921, anchors the waterfront end of the medina. Its whitewashed walls and arched windows look out over a harbour where wooden outrigger pirogues bob against a breakwater of black volcanic boulders. Walk north from the mosque and you reach Volo Volo, the main market, which is at its sharpest before 7 AM when the night's fishing catch arrives: yellowfin tuna, red snapper, and octopus laid out on wooden tables still wet from the morning rinse. Spice vendors stack vanilla pods, cloves, and cinnamon bark in pyramids that perfume the entire row. Friday afternoons everything shuts for prayer. Plan accordingly.

Booking Tip: No booking needed for the medina itself. But hiring a local French-speaking guide transforms the experience from wandering to understanding. Arrange one through your accommodation at least a day ahead. Arrive at Volo Volo before 7 AM for the fish auction. Leave before the midday heat makes the market oppressive. For guided walking tours, see current options in the booking section below.
Grande Comore Ylang-Ylang Distillery and Plantation Circuit

Comoros produces a significant share of the world's ylang-ylang essential oil, and May is the month the flowering season opens. The ylang-ylang trees, tall, with drooping branches hung with clusters of yellow-green star-shaped flowers, grow across the coastal lowlands of Grande Comore, and the scent is so pervasive on warm mornings that you can smell it from a moving car with the windows down. The distillation process happens in small, family-run operations that look more like outdoor workshops than factories: a wood-fired copper still, a coiled condenser, and a separator that draws off the oil floating on top of the distillate water. The first extraction, called 'extra' grade, takes about an hour and produces the most concentrated oil. The smell is intense, floral, almost dizzying at close range. Plantation visits are informal, usually arranged through a guesthouse or a local contact, and they typically run two to three hours including a walk through the groves and a demonstration of the distillation. The villages between Moroni and Mitsamiouli along the western coast have the densest concentration of working stills. Combine this with a stop at one of the vanilla-curing sheds where pods hang drying in the shade, their waxy surfaces already darkening and releasing that unmistakable bourbon-vanilla warmth.

Booking Tip: There is no centralised booking system for plantation visits. Ask your accommodation to connect you with a local guide who knows which distilleries are actively running in May, as not all start on the same day. A half-day circuit covering two or three operations is realistic. Bring cash for any purchases. For organised day tours of Grande Comore that include plantation stops, check current availability in the booking section below.
Itsandra and Chomoni Volcanic Coast Exploration

Grande Comore's coastline is not the powdered-sugar beach of a Maldives brochure. It is raw volcanic shoreline, black basalt sculpted by centuries of Indian Ocean surf into arches, blowholes, and tidal pools that glow turquoise against the dark rock. Itsandra, roughly 6 km (3.7 miles) north of Moroni, has one of the few sandy stretches on this side of the island. You will find a crescent of grey-black sand backed by coconut palms where fishing pirogues are pulled up above the tideline each evening. The water is warm, around 28 degrees C (82 degrees F) in May, and clear enough to snorkel directly off the beach over coral heads and sea urchin colonies. Further north, the road hugs the coast past villages where the smell of grilling mshakiki drifts from roadside stalls in the late afternoon. These are cubes of marinated beef charring over coconut-husk coals. Chomoni Beach, on the eastern coast about 20 km (12.4 miles) from Moroni, is the island's most photogenic stretch. It has lighter sand, a gentler entry to the water, and fewer people. The drive there crosses the island's interior, climbing through banana and breadfruit plantations before dropping back to sea level. May's seas can be rougher than the dry-season calm. Check swell conditions before snorkelling exposed sites.

Booking Tip: No advance booking needed for beach access. Transport on Grande Comore runs on shared taxis that follow no fixed schedule. Arrange a private car through your accommodation for a coastal day trip. Agree on the route and the return time before departing. Reef shoes are essential for entering the water anywhere on the volcanic coast. For organised coastal and snorkelling excursions, see current options in the booking section below.

Essential Tips

Insider knowledge and common pitfalls to avoid

Insider Knowledge
Moroni's best fish lands at Volo Volo before 7 AM, when the night-fishing pirogues return. By 9 the premium catch is spoken for. This means the fat yellowfin, the whole octopus, the red snapper with clear eyes. The equatorial heat has started working on whatever remains. If you want to see the real market, set an alarm and go hungry. The spice row behind the fish tables is where you'll find vanilla pods and whole cloves at a fraction of what they cost once they've been packaged for export. The wind shift from kashkazi (northwest monsoon) to kusi (southeast trades) happens in May. It produces mornings of startling clarity before the afternoon clouds build. Photograph the medina, the harbour, and Karthala's summit silhouette before 8 AM. By midday the volcanic peak will be wrapped in grey cloud and stay that way until the next dawn. This is also the window when the light on the coral-stone walls of the old town turns golden and warm. Fly to Moheli on your first or second day, not your last. Inter-island flights cancel without refund or rebooking assistance, and a missed connection to Moheli can strand your turtle-watching plans entirely. If your first attempt fails, you have days to try again. Leave it to the end, and a cancellation means missing your international departure from Moroni. Plan ahead. During Eid al-Adha, which likely falls mid-May in 2027, the entire city shuts down for three to four days. Stock water, snacks, and any medications before the holiday begins. The upside: Eid is the single best window to experience Comorian hospitality. If you are visibly a guest in the city, families will invite you to share the feast. Accept with both hands. Remove your shoes at the door. Eat with your right hand. The food will be some of the best you have in Comoros: slow-roasted goat, pilao rice fragrant with cardamom and cinnamon, and mkatra foutra, a dense coconut bread brushed with ghee and dusted with sesame seeds, that tears apart in layers.
Avoid These Mistakes
Assuming English will get you anywhere. It will not. Comorians speak Shikomori at home and French in schools, government, and commerce. English is essentially absent outside a tiny diplomatic circle. Even basic French, enough to negotiate a taxi fare, ask for directions, order food, transforms your experience from bewildered pointing to actual conversation. Download an offline French dictionary before you arrive, because mobile data coverage on Grande Comore is patchy and on Moheli nearly nonexistent. Do this. Attempting to summit Karthala without a local guide. The trail markings above the treeline are faint or missing, the volcanic terrain is monotonous grey scree in every direction, and clouds can roll in within fifteen minutes and reduce visibility to arm's length. People have gotten lost up there for days. A guide costs a fraction of what the rescue would, and they carry knowledge of the mountain that no map provides: which gullies flood, where the footing is solid, and when to turn back. Hire one. Packing for a Maldives-style beach holiday and arriving to find Grande Comore's coastline is mostly black volcanic rock with surf crashing directly onto jagged basalt. The swimming beaches exist: Itsandra, Chomoni, the coves near Mitsamiouli. But they are specific spots, not the default. If you walk into the water anywhere else without reef shoes, the sea urchins and sharp coral will make sure you remember. Bring the right footwear and adjust your expectations. This island's beauty is geological, not manicured.
