Het weer in Diani Beach (Diani) in juni

Regulars are consistent this month runs noticeably drier than May, with the official cold season not starting until July - though regulars note it can already feel chillier by the back half of this month, a real preview of what's coming. Our row backs that warm, genuinely humid read, 29C reading as a hot 31C, over 22.7C nights, with 56.1mm of rain across 15.9 days and humidity at 79 percent. Regulars are specific that rain here can be genuinely localized, falling in one part of the coast while a nearby beach stays completely dry at the same time. When a shower does hit, regulars describe it as warm rain that dries quickly once the sun reappears. The sea sits at a warm, swimmable 27.4C. The record: 10.4 hours of sun, a 21.9 kph wind and AQI 36.

Diani Beach's forum is split on July: some posters call this some of the coast's best weather, with days in the high 20s C and nights around 22C, while others describe a genuinely messier stretch of mostly cloudy skies and sharp showers with just a couple of sunny hours to work with. Humidity stays high regardless of which pattern you get. The consistent good news is the sea clears up for snorkeling and diving by July, and several posters noted Kenya's weather has gotten less predictable year to year, so it's worth going in with flexible expectations either way.

Forum posters name January and February as the hottest months here, but also the driest - averaging around 5 rainy days a month, the lowest rainfall stretch of the year by posters' count. Sea temperatures in January are reported around 27-28C, genuinely warm for swimming, though posters flag a practical local quirk: low tide (timing varies day to day, sometimes morning, sometimes afternoon) can pull the water back far enough to make swimming impractical for a stretch of any given day regardless of season. Posters generally rate the whole year as good here except for the wetter May-June stretch and a possible rainy patch around September-October, positioning January squarely within the best overall window.
