Comoros in November: Weather, Crowds & What to Expect

Grande Comore (Ngazidja) - Moroni & coastal lowlands

November brings a clear swing back toward humid, wet weather as the monsoon influence returns; showers are more frequent and heavy at times, and the surface temperature of the sea starts to climb. Local schedules become less predictable - small boat crossings will be cancelled more often and rural tracks can get sloppy. If traveling now, have flexible plans and bring quick-dry clothing and a good umbrella.

Mount Karthala & central highlands (Grande Comore interior)

November brings a return to more humid, unstable weather with rising showers and thunderstorms developing in the afternoons; higher elevations are quicker to cloud over than the coast. The foothills green up rapidly and small waterfalls reappear, but trekking becomes more of a wet-mountain affair. For safety, check volcanic alerts and avoid exposed ridge camping during storm spells.

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

November sees the reintroduction of more frequent showers and muggy conditions as the monsoon influence strengthens; rivers and gullies can fill rapidly after heavy rain. Travelers should expect more cancelled boat trips and plan extra travel time for inter-island connections. Short, intense rains punctuate otherwise hot days so pack quick-drying clothing and plan indoor alternatives in cities like Mutsamudu.

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

November ushers in the wet season return with warmer, stickier days and more frequent thunderstorms; sea conditions deteriorate and visibility for diving drops after heavy rain. Turtle nesting continues but beach access can be limited during storms. For travelers, allow flexible connections and expect lodges to alter schedules on short notice during violent showers.
