Heat index

During January, the heat index is calculated to be a very hot 38°C (100.4°F). Implement additional cautionary measures, heat cramps and heat exhaustion could occur. Prolonged activity might induce heatstroke.
Bear in mind that the heat index values are determined for shaded areas and light breezes. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', reflects the blend of air temperature and relative humidity to give a temperature impression. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.

Note: The maximum UV index of 7 during January leads to these instructions:
Stay clear of intense sun exposure. Solar protection is of utmost significance. Stay in the shade and limit direct sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its strongest. Remember, however, that not all shade structures provide full sun protection. Wearing a wide-brim hat can block approximately 50% of UV radiation, protecting the eyes.
