Heat index

The heat index for January is computed to be a torrid 38°C (100.4°F). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.
Heat index readings emphasize conditions of light breezes and shaded spots. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'real feel' or 'felt air temperature', reflects the feeling of heat when considering both air temperature and humidity. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.

Keep in mind that shade structures like parasols or canopies do not offer complete sun protection. To mitigate harm from sun exposure, pick sunglasses offering UVA and UVB defense.
