Is December Right for You?
Weigh the advantages and considerations before booking
Advantages
- + December brings the tail-end of the dry season, meaning you'll get postcard-blue water visibility for snorkeling around Chindini and Bimbini reefs without the summer plankton blooms
- + Hotel rates are still in shoulder-season territory - most properties drop their prices 25-30% from July-August peaks, and you'll likely get upgraded rooms just by showing up
- + The ylang-ylang harvest happens now, filling Moroni's hills with a perfume so intense you can taste it in the morning air before the trade winds pick up
- + Local families head to Itsandra Beach on weekends, creating impromptu grill parties where they'll share charred octopus and coconut water with anyone who brings cold drinks
Considerations
- − Afternoon thunderstorms roll in fast - one minute you're photographing the Friday market, the next you're sprinting through sheets of warm rain that turn dirt paths to red mud in minutes
- − The UV index hits 8 daily, meaning you'll burn in 15 minutes without protection, and the humidity makes sunscreen feel like you're wearing a plastic bag
- − Some inland hiking trails to Mount Karthala's crater become impassable after rain, and guides won't risk the final 200 m (656 ft) scramble on wet volcanic rock
Best Activities in December
Top things to do during your visit
Coral Garden Snorkeling Trips
December's water clarity peaks at 30 m (98 ft) visibility around Chindini Reef, where plate corals the size of dinner tables host parrotfish and the occasional hawksbill turtle. Morning conditions are typically calmer before the trade winds pick up around 11 AM, making 7 AM departures worth the early wake-up. The reef sits in a protected marine area, so you'll need a licensed operator who knows the current patterns that can sweep you toward deeper drop-offs.
Booking Tip: Book 3-4 days ahead through licensed marine operators - they'll check marine weather forecasts that aren't available publicly. Morning trips typically run 3-4 hours total including the 20-minute boat ride each way.
Mount Karthala Crater Trekking
The dry season trail to Karthala's 2,361 m (7,746 ft) summit is accessible in December's first half, before the cyclone season starts building momentum. The morning trail starts through vanilla plantations where you'll smell curing beans mixed with wet earth, then climbs through mist forest where the temperature drops 8°C (14°F) from base to crater rim. The final kilometer crosses recent lava flows - the 2005 eruption created a new route that guides now use to avoid older, unstable sections.
Booking Tip: Start hiking by 5 AM to beat both afternoon clouds and the heat - you'll want to summit by 10 AM. Licensed guides are mandatory for the crater sections, and they'll carry emergency gear for the altitude change.
Friday Market Photography Walks
Moroni's Friday market hits peak intensity when village women arrive at dawn with baskets of ylang-ylang, cloves, and vanilla threaded on palm fronds. The light is photographer-perfect between 7-9 AM when the sun angle makes the spice piles glow amber against the ochre walls of the old medina. December's slightly lower humidity means your lens won't fog constantly, and the morning temperatures stay comfortable until about 10:30 AM when the sun gets brutal.
Booking Tip: Join photography walks that start at 6:30 AM - most wrap up by 10 AM before the heat becomes oppressive and the afternoon storms build.
Traditional Dhow Sailing
December's trade winds blow steady from the southeast, good for traditional dhows sailing between Grand Comore's west coast and the smaller islands. The 12 m (39 ft) wooden boats use lateen rigs that catch these winds efficiently, and the 3-hour sunset sails from Itsandra Beach give you views of Mount Karthala's silhouette against orange skies. The wind keeps temperatures comfortable even in midday sun, and you'll likely spot flying fish skimming alongside the hull.
Booking Tip: Book afternoon departures that catch the sunset - winds are typically stronger then and the temperature drops to a comfortable 26°C (79°F). Trips usually include fresh coconut water and local snacks.
Volcanic Rock Coastal Hiking
The north coast's black lava flows create tide pools and blowholes that are accessible during December's lower tidal ranges. The 4 km (2.5 mile) walk from Iconi to Itsandra follows paths locals have used for centuries, passing salt pans where women harvest sea salt using techniques unchanged since the 1400s. The volcanic rock stays surprisingly cool even in midday sun, and December's lower humidity makes the coastal breeze feel refreshing rather than just hot.
Booking Tip: Time your walk for early morning or late afternoon - the black rock reflects heat intensely at midday. Local guides know which tide pools are safe for swimming and which have dangerous currents.

Early December
Mwaka Kogwa Festival
This Shirazi New Year celebration happens in villages across Grande Comore, featuring mock battles with banana leaves that predict agricultural fortunes. In Moroni's old town, families gather at the 15th-century mosque while elders read verses from old Qurans, then share honey cakes and fresh coconut milk. The scent of burning aloes wood mixes with the sound of traditional drums, and visitors are welcome to join the communal meals.

Insider knowledge and common pitfalls to avoid
Insider Knowledge
The best vanilla beans are sold by women at Friday market who keep them wrapped in banana leaves. Ask for 'vanille bourbon'. They'll show you how to identify quality by the oil content. Trust their fingers. They know.
Local fishermen at Chindini Beach will take you out at 5 AM for the dawn catch. Bring cigarettes as payment. They prefer them to cash. Hand them over. Cast the net.
The old French cemetery above Iconi has the best sunset views over Moroni. You'll need a local to show you the unmarked path. It starts behind the mosque. Follow quietly. Watch the sky burn.
December's ylang-ylang harvest means distilleries run 24/7. The scent carries for kilometers. Locals sell small bottles of oil for a fraction of perfume shop prices. Stock up. The fragrance lasts months.
Avoid These Mistakes
Assuming Moroni has the same infrastructure as other Indian Ocean islands is a rookie error. Power cuts happen daily. WiFi is slower than dial-up. Download offline maps before arriving. Do it.
Wearing revealing clothing in the old town is asking for hassle. Comoros is Muslim. Shorts/tank tops will attract unwanted attention, for women. Cover up. Blend in.
Booking hotels based on pool photos ends in disappointment. Most pools are empty during dry season due to water restrictions. Ask specifically if the pool is filled. Get it in writing.
