Traveller notes on Watamu
What people who have been say about the place — the year-round notes first, then month by month.
Forum posters describe February as bringing welcome, gentle sea breezes that pick up in the afternoon rather than anything uncomfortably strong, and specifically note seaweed isn't a problem on the beaches this time of year - a real seasonal nuisance in some other months. Posters name the October-to-March stretch overall as the best window for Watamu's beach conditions, with February falling comfortably within that favorable run. The general climate is described as hot and humid with occasional short, intense showers followed quickly by a return to sun and high humidity - a pattern consistent with this being one of the coast's drier, more settled months rather than a washout risk.
Watamu forum threads describe August as Kenya's cooler 'winter' by local standards, though the coast stays tropical - warm to hot days, cooler but rarely cold evenings, with a short shower possible in the morning or afternoon that usually clears within minutes. The standout theme across threads was wind: August is genuinely one of the windier months here, which forum regulars framed as a plus for kitesurfing and windsurfing but a real consideration for anyone hoping for calm-water snorkeling or diving, which posters said is better served by the October-to-March window instead.
