January weather forecast
Kariba, Zimbabwe

The beginning of the year in Kariba, Zimbabwe sees weather reflective of its tropical savannah climate. In juxtaposition to the later drier months, January often experiences important rainfall events with an average of 151mm (5.94") of rainfall, spread over approximately 24.7 days. Extensive cloud cover during this period accounts for an average of 40% of the sky, moderating the January heat somewhat. This month serves as an introduction to the typically warm and humid weather that characterizes Kariba. Looking ahead, subtle changes in the weather parameters can be anticipated as the year progresses.

Temperature

Kariba registers an average high-temperature of a still tropical 30.6°C (87.1°F) at the commencement of January, closely related to the preceding month. In the month of January, Kariba records a consistent average low-temperature of 21.6°C (70.9°F).

Heat index

The heat index value for January is evaluated at a very hot 38°C (100.4°F). Take additional safety steps, risk of heat exhaustion and heat cramps is notable. Prolonged activity may cause heatstroke.
Heat index guidelines indicate values are for light wind scenarios and shaded regions. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is achieved by amalgamating air temperature with the relative humidity readings. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.

UV index

January through July, with an average maximum UV index of 6, are months with the lowest UV index. A UV Index reading of 6 to 7 represents a high threat to health from unsafe exposure to UV radiation for average individuals.
Note: The maximum UV index, 6 during January, leads to the following recommendations:
Ward off overexposure. Defence against solar harm is crucial. UV radiation from the Sun is most intense between 10 a.m. and 4 p.m. Try to avoid direct sunlight during this period. Sun-protective clothing, a long-sleeved shirt and pants, a wide-brimmed hat, and UVA and UVB-blocking sunglasses are particularly helpful in blocking UV radiation's harmful effects.
