Comoros in March: Weather, Crowds & What to Expect

Grande Comore (Ngazidja) - Moroni & coastal lowlands

Expect the heavy rains to persist into March, but with clearer pockets between squalls; daytime heat remains high and nights muggy. Beach snorkeling is possible when seas calm, but visibility can be patchy after rain washes sediment into the water; choose organized operators who watch conditions. The threat of cyclonic systems is highest January-March, so follow local advisories and avoid remote coastal plans if a system is forecast.

Mount Karthala & central highlands (Grande Comore interior)

March keeps the central highlands within the rainy season: occasional dry mornings can open up fantastic, verdant vistas, but heavy storms remain frequent with the potential for rapid weather changes at altitude. The active nature of Karthala means ash-plume activity has occurred in the past - check official notices and ask rangers - and even minor eruptions can briefly blanket the highlands in fine volcanic dust.

Anjouan (Nzwani) - Mutsamudu, spice plantations & steep coasts

March keeps humidity high and rain showers common, though there are occasional long sunny stretches that rejuvenate waterfalls and streams inland. The coffee-and-clove plantations smell rich and trails lead through lush green terraces, but expect muddy, technical paths if you try to trek. Ferry crossings improve in the pockets of calm weather, yet always leave buffer time in your schedule for cancellations.

Mohéli (Mwali) & outer islets - marine park, turtles and quiet beaches

March sees frequent heavy showers and warm temperatures that keep the island lush and green; the marine-protected areas fill with life but water clarity depends heavily on the day after rain events. Whale sightings are still rare this month, but turtle hatchlings may be emerging on protected beaches. Travelers should bring flexible itineraries, solid waterproof gear, and expect small lodges to be quiet and occasionally closed during intense weather.
