January, like December, in Umudike, Nigeria, is another sweltering winter month, with an average temperature fluctuating between 22.5°C (72.5°F) and 36.2°C (97.2°F).

Temperature

The arrival of January marks a slight shift to an average high-temperature of a still very hot 36.2°C (97.2°F) from December's 35.3°C (95.5°F). Umudike experiences a significant reduction from daytime highs with an average low-temperature of 22.5°C (72.5°F) in January.

Heat index

In January, the heat index is evaluated at a burning hot 46°C (114.8°F). Attention: Heat exhaustion and heat cramps are quite likely. Heatstroke becomes a risk with continued exertion.
Observations indicate that the heat index values are for shady locations with light wind. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', takes into account both air temperature and humidity to illustrate what people actually feel. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. You should know that direct sun exposure can heighten weather effects, potentially elevating the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. 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. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
