In May, the shift in Valide's meteorological conditions is hardly detectable, with high temperatures identical to those of April. During May, Valide experiences a consistent low-temperature average of 21.9°C (71.4°F).

Heat index

May's heat index is appraised at a blistering 40°C (104°F). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.
It is emphasized that the heat index's values are meant for shaded zones with mild winds. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', joins air temperature with relative humidity to produce a temperature perception for humans. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. 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. As body temperatures escalate without effective heat release, one might face dehydration threats.

Enforce precautions and stick to sun safety measures. Preservation from skin and eye damage is essential. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is particularly strong, noting that parasols or canopies may not offer total sun protection. For optimum UV protection, wear sun-resistant attire complemented with a hat and quality shades.
