Weather in January
Temperature
January and December, with an average high-temperature of 30.1°C (86.2°F), are the warmest months.Heat index
The average heat index in January is computed to be a very hot 38°C (100.4°F). Extra safeguards are necessary to prevent heat exhaustion and heat cramps. Prolonged activity might cause heatstroke.Be advised, the heat index considers values for conditions in shade and with a light breeze. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', gauges the sensation of temperature factoring in the air's moisture content. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Children often do not understand the need to rest and hydrate. Thirst is a late manifestation of dehydration - therefore, it is essential to stay hydrated, particularly during prolonged physical activities.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.

Ward off overexposure. Defence against solar harm is crucial. Stay in the shade and limit sun exposure from 10 a.m. to 4 p.m., when UV radiation is most potent. Keep in mind that shade structures like parasols or canopies do not offer full protection. To best shield against UV radiation, choose sun-safe garments and dependable sunglasses.
