Kenya has two good windows: Jan–Mar and Jun–Oct. They sit either side of the season the climate record rules out, which is why the shoulder months matter here. The recommended window is Jan, Jun–Sep.

Verdict combines mean daytime high with rainy-day frequency. “Rainy days” is the share of days in the month with at least 1 mm of rain.
July is the driest month, with rain on 15% of days and daytime highs near 26.1°C (79°F). November is the wettest, at 73%. Temperature barely moves all year — just 3.5°C between the warmest and coolest months — so rainfall, not heat, decides when to go. The record rules out too wet in April, November.
