Your July weather guide
HotWeather in Kololi in July
July suits a Kololi holiday if warm air and sea matter more to you than reliable sunshine. Daytime highs average around 29°C, the sea is about 28°C, and rain falls on about 15 days. The catch is the combination of humidity, cloud and wet weather, rather than extreme heat. For a UK traveller, it is a clear step up in warmth, but not the strongest choice for a holiday built around sunny beach days.

Warm days, warm nights and little relief from humidity
Kololi's July daytime high is around 7°C above London's, so expect a noticeable change from a typical British summer. The average high stays below 30°C, but humidity of 80% means you should not judge comfort by temperature alone. Loose, lightweight clothing makes more sense than heavy fabrics, and a slower pace at midday is sensible if humid heat tires you. Nights average around 25°C, offering little cooling after sunset; look for accommodation with cooling if warm bedrooms disturb your sleep. The sea averages 28°C, making swimming a good fit for the month, though it will feel warm rather than provide a sharply cooling contrast to the air.
Plan for rain rather than uninterrupted beach weather
With about 15 rainy days, July calls for flexible plans rather than an expectation of dry weather throughout your stay. That does not tell you how long each spell of rain will last, so avoid assuming it will arrive as a brief shower at a convenient time. Sunshine averages about 3.5 hours within 12.7 hours of daylight: there is plenty of daylight, but much less actual sunshine. Pack a light waterproof and keep your daily plans easy to rearrange. July is a reasonable choice if you can enjoy the warmth despite wet spells. If your dates are flexible, April, March and May are better overall weather choices here.
