Is May Right for You?
Weigh the advantages and considerations before booking
Advantages
- + The tail-end of the rainy season means waterfalls around the Karthala volcano are still flowing, creating dramatic green backdrops for hikes that dry out by June. Expect curtains of water. They vanish fast.
- + Hotel rates are still in shoulder-season mode - you'll often get upgrades at waterfront properties in Itsandra and Moroni city center. Ask at check-in. Smile.
- + The Indian Ocean stays calm enough for reliable boat trips to nearby islands like Chindini and Mwali, with excellent visibility for snorkeling. Skippers leave early. Seas glass off.
- + Local fishermen are most active in late afternoon, creating photogenic scenes at Galawa Beach when the light turns golden. Nets arc. Boats silhouette.
Considerations
- − Afternoon thunderstorms hit 2-3 times per week, typically lasting 45 minutes but strong enough to halt boat departures. Plan buffer days. Bring a book.
- − The humidity at 70% makes walking uphill in Moroni's old quarter feel like breathing through a wet cloth, around midday. Pace yourself. Seek shade.
- − Some inland hiking trails remain muddy from April rains, routes above 600 m (1,970 ft) elevation on Karthala's slopes. Boots sink. Views soar.
Best Activities in May
Top things to do during your visit
Karthala Volcano Crater Day Hikes
May's variable weather creates the perfect window for crater walks - morning fog lifts by 9am for panoramic views of Grande Comore's coastline. The volcanic soil is still soft from April rains, making the 4-5 hour ascent more manageable than the rock-hard paths of July. You'll smell wild jasmine and see endemic dracaena trees flowering at mid-elevations. Start early. Bring water.
Booking Tip: Book through licensed operators familiar with changing weather patterns - they typically monitor conditions day-of and adjust departure times. See current hiking options in the booking section below. Flexibility wins.
Grande Comore Coastal Fishing Villages
May's calm morning seas make boat transfers between villages like Iconi and Mitsamiouli reliable. The fishermen's cooperative at Iconi loads catch onto wooden boats around 6am - worth timing your visit. The sea spray carries the scent of fresh tuna and the sound of outboard motors mixing with Swahili calls between crews. Wake early. Watch the ballet.
Booking Tip: Local pirogue trips work best before 10am when winds pick up. Look for operators with newer engines - older boats struggle against afternoon currents. Ask about horsepower.
Moroni Old Town Walking Tours
The narrow lanes around the medina are shaded enough that May's heat feels manageable until 11am. The Friday market at Volo Volo fills with vendors selling vanilla pods and ylang bark - the air thick with spice smells. Afternoon rain cools the stone buildings, creating puddles that reflect the carved doorways. Bring small coins. Bargain kindly.
Booking Tip: Start tours by 8am to avoid both heat and the daily 2pm thunderstorm. Licensed guides know which alleyways flood and can reroute quickly. Tip them.
Mwali Island Snorkeling Excursions
May water temperatures hover around 27°C (81°F) - warm enough for extended snorkeling without wetsuits. The visibility typically reaches 20 m (66 ft) before afternoon storms stir up sediment. Coral gardens around Nioumachoua feature giant clams and the occasional sea turtle sighting. Jump in. Look down.
Booking Tip: Multi-day trips book up faster than day tours - reserve 2 weeks ahead for overnight stays. Check operators include reef-safe sunscreen. Pack light.
Vanilla Plantation Visits
May marks the start of vanilla pollination season - you'll see farmers hand-pollinating each orchid bloom with tiny sticks. The plantations around Bambao send sweet floral scents drifting across the valley. Afternoon rain showers help the curing process, so tours continue rain or shine. Watch the wrist motion. Try it.
Booking Tip: Morning visits include demonstrations - afternoon tours are mostly walking through shaded drying areas. Book direct with cooperatives rather than hotel concierges. Save money.

Insider knowledge and common pitfalls to avoid
Insider Knowledge
The best vanilla comes from small farms in Bambao - look for pods that bend without breaking, not the brittle tourist-grade stuff. Sniff first. Buy long.
Local fishermen at Chindini beach will cook your catch for a small fee if you ask before 7am - bring limes and they'll supply the coconut rice. Eat with fingers. Lick them.
Moroni's covered market stays open during rain but gets slippery - the butchers' section has the best drainage if you need to cross quickly. Step carefully. Hold your nose.
Hotel generators kick in during outages. But they don't power air conditioning - book upper floors for natural breeze. Open windows. Hear the sea.
Avoid These Mistakes
Trying to visit multiple islands in one day - the boat schedule depends entirely on tides and weather, making tight connections impossible. Pick one. Stay longer.
Assuming credit cards work everywhere - even mid-range restaurants in Moroni prefer cash, after 4pm. Hit the ATM. Carry small bills.
Wearing hiking boots on Karthala - the volcanic scree destroys boot soles. Trail runners with good grip work better. Save your boots. Go light.
