The Kenya Meteorological Services has said the prevailing cold spell is expected to end by mid-September.
According to the Head of Forecasting at the department Samuel Mwangi, warmer temperatures will be experienced beginning next week.
“Giving way to warmer and eventually relatively hot days before the short rains season begins in the second week of October,” said Mwangi.
In a statement, the Weatherman said September is usually a transition from cold to warm season, however, the cold spell has been sustained owing to stable air in the morning mainly over the highland regions.
“This cold spell is associated with the stable air in the morning over the highland area that leads to development of low level clouds,” he said and added, “the low lying clouds inhibits sunshine rays heating the ground, and therefore giving us cold temperatures most of the morning.”
He noted that the afternoon gets warm when moist air from the Lake Victoria Basin displaces the cold air that mostly sees the afternoons get warmer temperatures. This also occasionally results in rainfall in the afternoon.
The cold season started in June and peaked in July and much of August when some regions including Nyahururu, experienced extremely cold temperatures that at times resulted into fog.
The cold season has been prolonged into September, which is normally warm especially in the highland East of the Rift Valley and its environs including Nairobi. “The rest of the country is warm as expected in September.”
