Traveller notes on Pemba in September
Other months in Pemba
Mozambique forum threads describe December in the Pemba/Cabo Delgado region as genuinely hot midsummer, commonly 30C+, with rain when it comes usually arriving as short, sharp storms in the late afternoon or early evening rather than settling in for the day. Several posters noted the heavier rainfall in this region typically doesn't arrive until mid-January into February, so December often means just the occasional rainy day breaking up a run of sunshine - locals described an odd rainy day as a welcome relief after a stretch of nonstop heat rather than a disruption. The consistent read: come prepared for real heat, with rain gear as a minor backup rather than the main concern.
Forum posters name June as a strong pick for diving here, sitting inside the dry winter season (roughly June through September) that brings the clearest water of the year. Posters are consistent that March, April and May count as the genuine rainy season to avoid, with June marking a clean transition into the more reliable dry stretch. Pemba is consistently named as a strong base and springboard for exploring the wider Quirimbas Archipelago, with direct flights from Johannesburg and Maputo making it a practical gateway. Posters generally rate June through October, alongside December-February, as the two best windows overall for diving conditions here.
