Is December Right for You?
Weigh the advantages and considerations before booking
Advantages
- + Sea turtles nest on Moheli's beaches from November through March. December is peak viewing season. You can watch hatchlings scramble to the water at dawn. Bring a red torch. Worth it.
- + The ylang-ylang harvest is in full swing on Grande Comore. The entire island smells like a perfume factory. Distilleries in Iconi will show you the traditional process. Free samples.
- + Hotel rates drop 30-40% from July-August peak. You'll have the coral gardens off Chindini Beach mostly to yourself. Snorkel early. Bring bread for fish.
- + Whale watching peaks in December as humpbacks migrate past the islands. The channel between Grande Comore and Mohéli becomes a marine highway. Boats leave at dawn.
Considerations
- − Afternoon thunderstorms roll in around 3pm. They can dump an inch of rain in 30 minutes. Moroni's unpaved side streets turn into red mud rivers. Pack sandals.
- − The humidity hits 85% by 10am most days. Your clothes will never fully dry. Camera lenses fog constantly when moving between air conditioning and outside. Keep gear in zip bags.
- − Some of the best hiking trails on Karthala volcano close intermittently due to slippery conditions. Guides won't take groups up during active rain. Check forecasts.
Best Activities in December
Top things to do during your visit
Sea Turtle Nesting Tours on Moheli
December is when green and hawksbill turtles lay eggs on Nioumachoua Beach. Hatchlings from November nests emerge at dawn. The 5km (3.1 mile) stretch becomes a nursery between 5-7am when the sand is cool enough for babies to race to the water. Local marine biologists lead small groups with red-filtered flashlights to avoid disorienting the hatchlings. Book early.
Booking Tip: Book through licensed operators 7-10 days ahead. Only 12 people maximum per nesting site per morning. Look for guides certified by the Mohéli Marine Park. They carry permits and know the exact nest locations. Check badges.
Ylang-Ylang Distillery Tours in Iconi
The yellow flowers bloom year-round but December's harvest means the copper stills run 24/7. The entire valley smells like jasmine crossed with banana. You'll watch workers unload 50kg (110 lb) sacks of petals, see the oil separate in glass flasks, and learn why Chanel No. 5 buys 80% of Comoros' production. The distilleries are family-run operations where someone always offers you spiced coffee. Say yes.
Booking Tip: Show up before 8am when the day's distilling starts. No reservations needed. Guides appreciate if you bring coffee beans or sugar as a courtesy gift. Small kindness goes far.
Karthala Volcano Crater Treks
Africa's largest active volcano has a 3km (1.9 mile) wide crater that's accessible in December's cooler mornings. The 8-hour round trip from 1,800m (5,905 ft) starts at 5am to beat the clouds that roll in by noon. The lunar landscape inside the crater contrasts with the lush forest you hiked through. The caldera floor still steams in places from 2005 and 2006 eruptions. Surreal.
Booking Tip: Only attempt with certified guides who carry GPS and emergency beacons. Weather can change in minutes. Book 2-3 days ahead. Start hiking by 5:30am latest. No exceptions.
Humpback Whale Watching in the Mohéli Channel
December sits in the middle of whale migration season when humpbacks travel south to Antarctic feeding grounds. The 35km (22 mile) channel between Grande Comore and Mohéli becomes a playground. You'll often spot blows from shore. But boats get you within 100m (328 ft) of 15-meter (49 ft) adults teaching calves to breach. Mornings offer the calmest seas and best lighting for photography. Bring zoom.
Booking Tip: Morning departures (6-8am) have 80% sighting rates versus 40% in afternoons. Choose operators with hydrophones. Listening to whale songs through underwater speakers is surreal. Bring a jacket.
Grand Marche Spice Market Tours in Moroni
Moroni's covered market reaches peak chaos in December when clove harvest arrives from the hills. The spice section assaults your senses. Vanilla beans braided like rope, cinnamon bark that tastes sweet when chewed, and cloves so fresh they still snap. Vendors hawk from concrete stalls built in 1975. The best vanilla deals happen before 9am when cruise ship passengers haven't arrived yet. Beat crowds.
Booking Tip: Bring small bills and expect to haggle. Start at half the asking price for vanilla. The market's spice section is in the northwest corner. Identify it by the overwhelming scent of cloves mixed with cardamom. Follow your nose.

Mid December
Mawlid Festival Celebrations
The Prophet Muhammad's birthday brings processions through Moroni's medina quarter. Men in white robes chant dhikr while women throw perfumed water from balconies. The night before, families prepare halawiyat (honey-soaked pastries) that they'll distribute to neighbors and passing children. The celebrations peak at the Badjanani Mosque where the muezzin's call echoes across the harbor at sunset. Join in.

Insider knowledge and common pitfalls to avoid
Insider Knowledge
The ylang-ylang distilleries in Iconi will fill any container you bring. Bring a 100ml bottle and they'll top it up for the price of conversation. Smells like heaven.
Local boats to Mohéli leave from Chindini at 6am when seas are calmest. Afternoon departures get canceled 40% of the time in December. Wake early.
Turtle watching works best during spring tides (new and full moon) when more nests are exposed. Check the lunar calendar before booking. Time it right.
Karthala guides won't mention this. But the crater rim is 2,300m (7,546 ft) above sea level. You'll feel the altitude if you rush the climb. Pace yourself.
The best vanilla comes from small stalls behind the Grand Marche main building. Look for beans that bend without breaking and smell like bourbon. Sniff first.
Avoid These Mistakes
Booking afternoon whale watching trips when morning has 2x better sighting rates and calmer seas. Skip p.m. slots.
Karthala eats sneakers alive. Volcanic scoria chews soles to shreds and turns blistering by noon. Pack leather boots. Your feet will thank you.
Mohéli keeps cash scarce. Only two ATMs serve the whole island and both gulp empty by Friday. Withdraw on Monday. Bring euros as backup.
Travel insurance is non-negotiable. The closest decompression chamber sits 1,400km (870 miles) away in Reunion. A speedboat medevac costs fortunes. Buy the coverage.
