طقس Diani Beach (Diani) في سبتمبر

September here is described as fine weather with the occasional short shower, and notably not as hot as the rest of the year. Our rain figures say exactly that, in a way either number alone would hide: 44.8mm spread across 15.2 days is about three millimetres on each day it rains - frequent, brief, and not a reason to change a plan. Air is 28.7C but reads as 32C at 77.4 percent humidity, and the nights hold 22.6C. The sea is 26.6C. The caveat regulars add is about conditions rather than weather: it is windy now, 18.4 kph, so the water turns choppy and visibility drops - a better month for the beach than for diving. The record: 10.8 hours of sun and AQI 35.

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.
