Weather in January

Heat index

Throughout January, the heat index is evaluated at a very hot 38°C (100.4°F). Exercise more precautions, heat cramps and heat exhaustion are potential risks. Continuous activity could precipitate heatstroke.
Evaluating the heat index requires understanding its values in the shade and with gentle winds. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a single figure representing how weather conditions feel when combining temperature and humidity. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are especially vital to children. Young ones regularly neglect the requirement for rest and fluid replenishment. Thirst is a late stage of dehydration - so, it is necessary to keep hydrated, particularly during extended periods of physical exertion.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. As body temperatures escalate without effective heat release, one might face dehydration threats.

Humidity

The average relative humidity in January is 88%.

UV index

January, June through October, 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 health hazard from exposure to the Sun's UV rays for ordinary individuals.
Note: The daily high UV index of 7 in January translates into this advice:
Skirt overexposure. People with light complexions might get scorched in under 20 minutes. Limit direct sun exposure and seek shade between 10 a.m. and 4 p.m., the time of the most intense UV radiation, noting that shade structures may not provide total sun protection. Experience reduced UV exposure by about half when donning a wide-brim hat.
