We felt safe walking around Moroni even after dark, which surprised us given how little we'd read about Comoros before arriving, and the whole trip ended up feeling refreshingly authentic and untouched by mass tourism. Around the Medina and the Friday Mosque we dressed modestly, shoulders and knees covered, and removed our shoes before entering any mosque. Euros turned out to be far more useful than dollars for everyday purchases. The market near the Old Port was the highlight of our stay, grilled seafood stalls and the scent of vanilla drifting from vendors selling mataba nearby. Itsandra Beach, almost empty when we visited, gave us a genuinely peaceful afternoon away from the town center.
Traveller notes on Moroni
What people who have been say about the place — the year-round notes first, then month by month.
Forum posters describing Grande Comore note December through February brings the lowest hotel prices, generally a sign of the region's wetter, cyclone-season low period in the Southern Indian Ocean, with March sitting at the tail end of that stretch as conditions gradually improve. Posters contrast this with early October, explicitly within the dry season, describing around 28C heat with humidity near 100% in the island's forested interior even during that drier window. Given the limited March-specific detail available for Moroni, this note leans on that broader seasonal shape: expect March to still carry meaningful rain and humidity as the wet season winds down, improving but not yet at the dry-season comfort of the following months. Posters generally recommend a private taxi (negotiable from around 20 EUR) for the Moroni airport transfer and note a 30 EUR cash visa-on-arrival, practical logistics as relevant to a Moroni visit as the exact weather.
Detailed trip reports for Comoros are genuinely scarce on the forum - one visitor recently back from Grande Comore specifically noted how hard it was to find much information about traveling there before their trip. Posters who have visited generally describe the islands as a warm, humid, little-touristed volcanic destination in the Indian Ocean. Given the sparse destination-specific detail, this note is grounded in the well-established regional pattern shared with nearby Indian Ocean islands: a drier, cooler southern-hemisphere-winter stretch roughly May through October, and September sits within that comparatively drier window, ahead of the hotter, wetter cyclone-season months from November through April.
