April weather forecast
Voi, Kenya

April continues to follow the weather pattern set by March with a slightly cooler climate. The ever-changing weather brings about overcast sky conditions, accompanied by periods of sunshine. It witnesses the highest number of rainfall days, standing at 26.5 days. The lingering rainy conditions make April an unpredictable month, which is a draw for some visitors seeking the thrill of an authentic African weather experience. The dynamic pattern prepares the city for the shifting weather conditions in May.

Temperature

The arrival of April records an average high-temperature of a warm 29.3°C (84.7°F), closely related to the 30.8°C (87.4°F) observed in March. During April, Voi experiences a consistent low-temperature average of 20.4°C (68.7°F).

Heat index

April's heat index is computed to be a very hot 35°C (95°F). Incorporate special precautions, risk of heat exhaustion and heat cramps is substantial. Sustained activity could cause heatstroke.
Research indicates the heat index considers values in shaded locales and with light winds. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.

The months with the lowest UV index in Voi are January through December, with an average maximum UV index of 6. A UV Index of 6 to 7 symbolizes a high health hazard from exposure to the Sun's UV radiation for the average person.
Note: In April, a regular UV index of 6 translates into these guidelines:
Undertake precautions and comply with sun safety standards. Protection from skin and eye injury is vital. Stay out of direct sunlight between 10 a.m. and 4 p.m., when UV radiation is most intense, and remember that not all shade structures provide complete protection. For minimizing sun-related eye damage, always choose sunglasses with UVA and UVB coverage.
