Weather in December
Temperature
Gerehu's warmest weather arrives in December, when temperatures average a high of 30.2°C (86.4°F) and a low of 24.5°C (76.1°F).Heat index
The heat index value during December is computed to be a sweltering 37°C (98.6°F). Implement additional safety measures to avoid heat cramps and heat exhaustion. Persistent activity might trigger heatstroke.In the scope of the heat index, its values resonate with shade and light wind conditions. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. 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 are particularly relevant to children. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.

January, March through May, October through December, with an average maximum UV index of 7, are months with the highest UV index. A UV Index reading of 6 to 7 represents a high threat to health from unprotected exposure to Sun's UV rays for ordinary individuals.Note: In December, a regular UV index of 7 translates into these guidelines:
Sidestep overexposure. Individuals with fair complexions risk burning in fewer than 20 minutes. The Sun's UV radiation is most potent between 10 a.m. and 4 p.m. Try to limit direct exposure to the Sun during this period. For excellent sun protection for the eyes, ears, face, and neck, consider a wide-brim hat.
