Heat index

The heat index for May is estimated at a torrid 38°C (100.4°F). Ensure additional precautions, heat exhaustion and heat cramps may be expected. Heatstroke could occur from sustained activity.
Evaluating the heat index requires understanding its values in the shade and with gentle winds. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a single figure representing how weather conditions feel when combining temperature and humidity. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
