Weather in January
Temperature
Sedayu notes a minor change to an average high temperature of a still warm 28.9°C (84°F) in January, remaining consistent with December. The low temperature average during January reflects a slight decrease to a still warm 24.3°C (75.7°F) from the day's peak.Heat index
January's mean heat index is calculated to be a very hot 35°C (95°F). Implement enhanced safety actions, heat cramps and heat exhaustion could occur. Sustained activity might result in heatstroke.The heat index's values are generally associated with conditions in shade and light breezes. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'real feel', evaluates the perceived heat by adding the effect of moisture in the air. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.
