Weather in January
Temperature
January, February and December, with an average high-temperature of 27.2°C (81°F), are marked as the warmest months.Heat index
In January, the average heat index is appraised at 29°C (84.2°F). Exposure and extended activity could potentially cause a state of fatigue and lead to heat cramps.It is worth noting that heat index values are gauged for conditions in the shade and light breezes. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', arises from combining readings of air temperature and relative moisture content. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
