December weather, activities, events & insider tips
December Weather in Moroni
Is December Right for You?
Advantages
- Rainy season transitions bring lush, green landscapes and dramatic cloud formations over Mount Karthala - the volcano looks particularly striking with mist clinging to its slopes, and waterfalls around the island run at their fullest
- Fewer tourists mean you'll have beaches, markets, and historic sites largely to yourself - the Medina feels authentically local rather than tourist-oriented, and you can actually have conversations with vendors without competing with cruise ship crowds
- Sea conditions start improving mid-month as the rainy season winds down, making it increasingly viable for boat trips to nearby islands and fishing villages - visibility for snorkeling typically reaches 15-20 m (49-66 ft) by late December
- Ylang-ylang flowers are in full bloom across the island, filling the air with the fragrance that made Comoros famous in the perfume industry - December is when distilleries operate at peak capacity and some offer informal tours
Considerations
- Rain showers are unpredictable and can be heavy - expect 10 days with rainfall, though showers typically last 30-90 minutes rather than all day. Roads to rural areas occasionally become muddy and difficult to navigate, particularly the route up Mount Karthala
- December sits awkwardly between seasons, so some boat operators reduce schedules or cancel inter-island trips on short notice due to sea conditions - you'll need flexibility in your itinerary if island-hopping is a priority
- High humidity at 70% combined with temperatures around 30°C (86°F) creates that sticky, energy-sapping heat that makes midday exploration uncomfortable - locals retreat indoors between noon and 3pm for good reason
Best Activities in December
Mount Karthala Volcano Hiking
December offers some of the most dramatic hiking conditions on this active volcano - the landscape is exceptionally green after months of rain, and morning mists create an otherworldly atmosphere. Start at dawn (5am departure from Moroni) to complete the 8-10 hour round trip before afternoon clouds roll in. The trail covers roughly 12 km (7.5 miles) with 1,400 m (4,593 ft) elevation gain. Weather can shift quickly, so you might encounter light rain even in December, but trails are more stable than during peak rainy season. Temperatures at the summit drop to around 15°C (59°F), a welcome relief from coastal heat.
Moroni Medina Walking Tours
The old town is best explored in December's relatively dry conditions, and the reduced tourist numbers mean you'll experience authentic daily life. The narrow streets and historic architecture look particularly photogenic with dramatic December cloud formations overhead. Best timing is early morning (7-9am) when the fish market operates at full intensity, or late afternoon (4-6pm) when temperatures drop and locals emerge for evening shopping. The Medina covers roughly 2 sq km (0.8 sq miles) of winding alleys - plan for 3-4 hours of wandering. Friday mornings see the Grand Mosque area bustling with worshippers, offering cultural insight if you're respectful.
Ylang-Ylang Distillery Visits
December is peak production season for ylang-ylang essential oil, and several distilleries around Moroni operate at full capacity. The flowers are harvested early morning, and distillation happens throughout the day - visiting between 8am-11am lets you see the entire process. The scent is overwhelming in the best way possible. Most distilleries sit 5-15 km (3-9 miles) outside Moroni in rural areas where December's greenery makes the drive scenic. Expect to spend 1-2 hours at a distillery, including explanation of the process and usually an opportunity to purchase oil directly at better prices than tourist shops.
Coastal Snorkeling and Beach Time
By late December, sea conditions improve noticeably as the rainy season tapers off. Visibility reaches 15-20 m (49-66 ft) on calm days, and water temperature stays comfortable at 27-28°C (81-82°F). The coral reefs around Itsandra Beach (7 km/4.3 miles north of Moroni) and Maloudja (12 km/7.5 miles south) offer decent snorkeling with minimal current. December sees fewer boats disturbing the water, so marine life is relatively active. Mornings (8-11am) typically offer the calmest conditions before afternoon breezes pick up. UV index of 8 means sunscreen is non-negotiable - reapply every 90 minutes in the water.
Local Market and Street Food Exploration
December brings seasonal produce to Moroni's markets - mangoes, lychees, and breadfruit are at their peak, and vendors are more willing to chat and offer samples when tourist crowds are thin. Volo Volo Market (the main market) operates daily but is most vibrant Thursday and Friday mornings. Street food stalls around the port serve fresh grilled fish, cassava fritters, and mkatra foutra (coconut bread) from late afternoon through evening. The covered market sections provide shelter if December showers hit. Budget 2,000-5,000 KMF for a filling street food meal, and bring small bills - vendors rarely have change for large notes.
Inter-Island Day Trips
While December isn't peak season for boat travel, late December sees improving conditions for trips to nearby Moheli or Anjouan islands. The journey to Moheli takes 3-4 hours by boat when seas cooperate, offering opportunities to see sea turtles and potentially dolphins. December's variable weather means you need serious flexibility - boats cancel regularly, and you might wait days for suitable conditions. If you do make it, you'll have these islands almost entirely to yourself. The marine park around Moheli is particularly worthwhile, with sea turtle nesting sites and pristine coral reefs.
December Events & Festivals
Comoros Independence Day
December 12th marks independence from France in 1975. Moroni sees official ceremonies at the Place de l'Indépendance with military parades, traditional dancing, and speeches. The atmosphere is more locally significant than tourist-oriented, but visitors are welcome to observe. Evening celebrations include music performances and street gatherings, particularly around the Medina. It's one of the few times you'll see large crowds in December.
