Heat index

The average heat index in May is appraised at a burning hot 50°C (122°F). Notice: Heat cramps and heat exhaustion are likely. Continued strenuous activity might lead to heatstroke.
Heat index determinations are made taking into account the shade and light air movements. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', gauges the sensation of temperature factoring in the air's moisture content. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Children frequently do not comprehend the need for rest and hydration. Thirst is an advanced stage of dehydration - staying hydrated, especially during extended physical exercises, is essential.
When faced with excessive heat, the human body begins to perspire, utilizing the cooling benefits of sweat evaporation. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.

Humidity

In May, the average relative humidity is 48%.

Refrain from overexposure. Fair-skinned individuals could burn in under 20 minutes. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. Arm yourself against UV rays' harm with protective apparel and UV-filtering shades.
