January weather forecast
Shanzu, Kenya

January, like December, is another hot summer month in Shanzu, Kenya, with an average temperature varying between 31.2°C (88.2°F) and 24.3°C (75.7°F).

Temperature

The average high-temperature during January registers at a still tropical 31.2°C (88.2°F), closely corresponding to the preceding month. An average temperature of 24.3°C (75.7°F) is recorded during the nights in January.

Heat index

In January, the average heat index is calculated to be an extremely hot 40°C (104°F). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.
Consider that heat index readings are for situations in the shade and light wind. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'feels like' or 'apparent temperature', reflects the blend of air temperature and relative humidity to give a temperature impression. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Children frequently do not understand the need for recuperation and hydration. Thirst, being a late manifestation of dehydration, underlines the need to hydrate frequently, especially when engaging in prolonged physical exercises.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.

UV index

January through June, September through December, with an average maximum UV index of 7, are months with the highest UV index. A UV Index estimate of 6 to 7 represents a high health hazard from exposure to the Sun's UV rays for the average person.
Note: The UV index of 7 during January leads to these advisories:
Guard against overexposure. Protection from sun-induced harm is essential. Limit your exposure to the sun's UV radiation, which is strongest between 10 a.m. and 4 p.m., and note that parasols or canopies may not provide full sun protection. For holistic sun protection encompassing the eyes, ears, face, and neck, a wide-brim hat is key.
