The August-September weather is usually mixed, and is traditionally rainy and cold, with a brief dry season beginning end of August till October.
Early in the week, Met said dry weather is expected over most parts of Kenya next month, a condition that could drag on until October, according to a new weather forecast.
The larger eastern Kenya is especially expected to be warmer and dry in the next three month, while western Kenya could be wetter than usual.
The forecast was given by the Igad Climate Prediction and Applications Centre, which is based at Dagoretti-corner in Nairobi.
The current forecast means the ongoing drought in northern Kenya will probably only end when the short rains season begins in October.
