Residents of Nairobi should prepare for a mostly cloudy day with a mix of mild morning temperatures and a short, intense spell of thunderstorms in the mid-afternoon. Typical for this transitional season, the city will experience variable conditions, including cloud cover, showers, and comfortable temperatures.
Morning to Early Afternoon
The day began on a cool note, with temperatures around 18 °C at 10 AM under thick cloud cover. By late morning, readings are expected to rise to 21 °C by noon and peak near 25 °C around 2 PM. The persistent clouds will keep the city comfortably cool, although sunshine will remain mostly blocked during the early hours.
Mid-Afternoon Showers
Forecasters predict that thunderstorms will develop around 3 PM in parts of the city. These short-lived storms could bring heavy rain, thunder, and lightning, with temperatures dipping slightly to 23 °C. Residents are advised to carry umbrellas or light raincoats, as outdoor activities and city traffic may be affected during the showers.
Late Afternoon to Evening
Following the storms, skies will gradually clear but remain mostly cloudy, with intermittent breaks later in the evening. Temperatures will cool to 22 °C by 4 PM and drop further to 17 °C by 11 PM. Damp roads may persist, so motorists and pedestrians should exercise caution during evening commutes.
Tips for the Day
- Plan ahead: Schedule key errands and outdoor activities for the morning or evening when the weather is more stable.
- Stay dry: Keep an umbrella handy during the mid-afternoon thunderstorms.
- Exercise caution: Watch for slippery roads and walkways during and after rain.
- Enjoy the breaks: Mild temperatures between downpours are ideal for light outdoor activities like strolls or casual errands.
