Heat index

In May, the heat index is evaluated at a very hot 39°C (102.2°F). Greater safety measures are needed, risk of heat exhaustion and heat cramps is high. Continuous activity might trigger heatstroke.
When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is an aggregate value of air's warmth and moisture to show the human-felt temperature. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Young ones often disregard the necessity to rest and hydrate. Thirst usually indicates advanced dehydration - hence, it is key to stay hydrated, particularly during ongoing physical activities.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.

Avoid excessive sunlight. Those with lighter skin may experience burning in less than 20 minutes. Stay out of direct sunlight between 10 a.m. and 4 p.m., when UV radiation is most intense, and remember that not all shade structures provide complete protection. Sun-related eye harm can be minimized with proper sunglasses offering UVA and UVB coverage.
