Is December Right for You?
Weigh the advantages and considerations before booking
Advantages
- + The rain arrives in short, theatrical bursts that leave volcanic soil smelling of wet earth and frangipani, then clear to reveal skies that are, for a few hours, a startlingly clear blue.
- + December sits between the peak of dry season and the full onset of wetter months, meaning interior trails on Grande Comore are still passable and Karthala's slopes are lively green, while the sea hasn't yet churned up from heavier rains.
- + Life in Comoros keeps a distinctly local rhythm. Morning fish auctions in Moroni's old port smell of salt and diesel, and evenings in Itsandra fill with kids playing football on sand, not resort music.
- + It's a month for having places to yourself. You might be the only person walking the black sand beach at Chomoni, with just your own footsteps and the Indian Ocean's constant, low roar.
Considerations
- − That 8.6 inches (218 mm) of rain isn't gentle mist; it's tropical downpours that can turn unpaved tracks on Mohéli into slick, red mud within minutes, stranding you or cancelling planned waterfall hikes.
- − The humidity, constant 70%, makes everything feel slower and stickier, if you're attempting the Karthala climb. Your clothes will be damp with sweat before you've left the tree line.
- − While not peak season, December sees a noticeable uptick in visitors from regional neighbors, so the handful of comfortable guesthouses on Mohéli or Anjouan get booked surprisingly fast.
Best Activities in December
Top things to do during your visit
Karthala Volcano Summit Hikes
December is likely your last clear window before cloud forest becomes perpetually socked in. Air at 2,361 m (7,746 ft) is noticeably cooler, a relief from coastal humidity, and views across Grande Comore to other islands are often crystal clear in early mornings. The trail itself is a sensory journey from hot, sun-baked basalt lower down to damp, mossy chill and wind in giant heather trees near the rim.
Booking Tip: This is a serious, two-day undertaking requiring a licensed guide who knows the route and can arrange camping gear. Don't attempt it alone. Book at least a week ahead through reputable operators (see current guided trek options in booking section below).
Mohéli Marine Park Snorkeling & Turtle Watching
The sea around Mohéli is still warm and clear enough for spectacular visibility, but December's real draw is green turtles. This is nesting season, and with a guide from the park association you can quietly observe them digging nests on moonlit beaches of Itsamia; it's all shuffling sand, heavy breathing, and profound stillness. Snorkeling next day among healthy coral is the perfect sunny counterpoint.
Booking Tip: Turtle watching is strictly regulated to protect animals. You must go with official park guide. Arrange this directly through Mohéli Marine Park office in Nioumachoua or via tour operator on Grande Comore well in advance, as spaces are limited.
Grande Comore Coastal & Cultural Driving Tours
The circuit of Grande Comore is perfect December road trip material. Showers tend to be brief and localized, so you can time drives between them. You'll go from busy, spice-scented chaos of Volo Volo market in Moroni to stark, wave-battered lava fields of north coast, where only sound is wind and crash of surf. Stopping in villages like Ikon lets you see Comorian art of 'grand mariage' preparations, which often peak in December. Air fills with rhythmic pounding of rice and scent of ylang-ylang being distilled.
Booking Tip: Hire a local driver-guide who can translate and navigate informal village protocols. Full island tour is a long day. Start early to beat afternoon heat and potential rain. Look for operators offering full-day itineraries (current options are in booking widget).
Anjouan 'The Perfumed Isle' Exploration
Anjouan in December is a feast of scent and sight. Steep, terraced hillsides are lush from recent rains, making clove and ylang-ylang plantations intensely fragrant, in humid air after morning shower. Mists cling to 1,575 m (5,167 ft) peak of Mount Ntringui, creating moody, almost mystical atmosphere in old Sultanate capital of Mutsamudu, where you can wander cool, shadowy lanes of the medina.
Booking Tip: Getting to Anjouan requires short flight or potentially rough ferry. Once there, mountainous roads are best navigated with 4x4 and driver who knows them. Book inter-island transport and guide simultaneously, as logistics are interconnected.

Insider knowledge and common pitfalls to avoid
Insider Knowledge
The best fish in Moroni isn't at a restaurant. Be at the old port by 7 AM. Watch the pirogues slide in, nets still dripping. Buy a just-caught bonito or capitaine straight from the fisherman's hand. Walk it to a grill house in the medina. They'll sear it with chili-lime for pocket change. Fresh, fast, unbeatable.
On Grande Comore, the west coast road south of Moroni catches every afternoon cloud. Spot a clear morning? Drive south first. Hit Chomoni's beach before the skies open. Leave the drier east coast villages like Ikon for later. Sun favors them after lunch.
On Anjouan or Mohéli, bring a gift. A kilo of sugar. A packet of tea. Hand it to the village elder or your guide's family. It's custom, not a bribe. Respect travels farther than cash.
Rain pounding Moroni? Don't bolt for your hotel. Slip into the old Friday Mosque near the port. Centuries of wood and prayer hush the storm. Listen to rain drum the roof. Cool, dark, perfect.
Avoid These Mistakes
Underestimating the terrain. 'Island' doesn't mean flat. Hikes are steep. Roads are rocky tracks. Distances double on the ground. Plan time, not miles.
Packing only for the beach. Microclimates swing hard. Coast: 30°C (86°F) and sunny. Karthala caldera: 15°C (59°F) and windy. Same day. Pack layers.
Trying to hop every island in one week. Inter-isferry rides are slow, weather-bound. Pick one island, maybe two. Dig deep. Rushing traps you in transit.
