Traveller notes on Bissau in April

Other months in Bissau

Forum posters are direct that July through October covers Guinea-Bissau's rainy season, generally recommending travelers avoid this stretch if possible, with August and October singled out as the worst months specifically. Posters describe Bissau's roads, already full of potholes, becoming genuinely hazardous during the rains, with real flooding a possibility for anyone staying in the city, and rain boots recommended as practical footwear given how unpredictable the ground conditions get. Posters consistently point to November instead as a better-regarded month, offering both less rainfall and less oppressive heat than the peak rainy months. Posters generally rate July as one of the more challenging months to visit Bissau, heavy rain and difficult road conditions the main obstacles, with November a clearly preferred alternative just a few months later.

Forum posters describe the tail end of the year, heading toward November, as a good window for Guinea-Bissau specifically because rainfall drops off and the worst of the summer heat eases - a useful marker that January, further into that same dry stretch, should carry the pattern forward with even less rain risk. Posters also note that by the end of the rainy season the mosquito population drops off drastically, a practical upside of visiting during this drier part of the year. Given how few detailed trip reports exist for Bissau specifically, posters' discussion tends to center more on safety and general travel logistics than granular weather detail, though the broader dry-season framing for this stretch of the calendar is consistent.

    Almost nothing falls between November and May, and the harmattan carries Saharan dust over the city for part of it. It is the only stretch when the roads inland and the boats out to the Bijagos run to anything like a schedule. Source ↗
