There are two dominant influences on the climate in Kenya: altitude and monsoon winds coming from the Indian Ocean. The climate of Kenya is made up of two rainy seasons and two dry seasons, according to Expert Africa. The onsets of the rainy seasons are determined by the monsoon winds.Know More
The heaviest rainy season occurs from April through June. From late June to October, weather is cool and relatively dry before another abbreviated rainy season from November to December. Mid-December through March is the warmest and driest period of the year.
Because of the warm, dry weather, the main tourism season in Kenya begins around the middle of December and continues through March, according to Expert Africa. Temperatures in Nairobi reach a high point in April when average temperatures top 80 degrees Fahrenheit daily, while temperatures in July, August and September can dip to lows in the 30s. Because of the country's proximity to the equator, the heat and glare of the sun are intense.
While long periods of rain are not uncommon, during the rainy season, rainfall is most commonly characterized as a torrential downpour lasting for about 30 minutes, according to Expert Africa. After a strong rain, the sun typically reappears and the ground dries in a matter of minutes.
