Heat index

May's heat index is computed to be a blistering 42°C (107.6°F). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.
Heat index's context suggests values are appropriate for shady areas and slight breezes. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', binds temperature metrics with humidity values to give a sense of the actual warmth. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. 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 are particularly relevant to babies and toddlers. Children often overlook the necessity for resting and fluid replenishment. Thirst is a late sign of dehydration - thus, it is critical to stay hydrated, especially during extended periods of physical activities.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.

Take precautions against overexposure. Fair-skinned people may get burned in less than 20 minutes. 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. A hat with a broad brim is indispensable, filtering out up to half of UV rays. Beware! The strength of the UV rays is significantly increased by the reflection of the water and sand.
