It expects warmer-than-average temperatures across the season, with higher probabilities over Kwale, Mombasa, Kilifi and Lamu.

The IGAD Climate Prediction and Applications Centre (ICPAC), the regional climate body, said in its summary of 10 September 2026 that wetter-than-normal conditions are more likely across the Greater Horn of Africa. It gave a high chance of seasonal totals above 400 mm in parts of central Kenya and the Lake Victoria Basin, among other areas.

In Nairobi, the Nairobi Rivers Commission has opened the emergency spillway at Nairobi Dam, Capital FM reported on 19 October. Chief executive Joseph Muracia said in a statement that the opening is part of planned interventions to improve the dam's preparedness for heavy rainfall. He told residents downstream to keep away from the flowing water and river channels.

Capital FM reported on 29 August that Mary Muthoni Muriuki, Principal Secretary for Public Health and Professional Standards, had announced the Ministry of Health's El Niño contingency plan. The ministry said it is particularly concerned about water- and food-borne diseases, including typhoid, cholera, dysentery and hepatitis A, as well as other diarrhoeal illnesses. Its advice: boil or treat drinking water and keep it in clean, covered containers; wash hands with soap and safe water; avoid food that has been exposed to floodwater; and do not walk or drive through floodwater. It also cautioned against taking antibiotics without a prescription and advised seeking care early for persistent fever, severe headache, abdominal pain, vomiting, profuse watery diarrhoea, blood in stool, unusual weakness or signs of dehydration.

The bulletin says the weekly forecast should be used together with the daily and five-day forecasts and the authority's updates and advisories. County-specific forecasts are available from the offices of the County Directors of Meteorological Services.
