Temperature

With an average high-temperature of 34.8°C (94.6°F) and an average low-temperature of 22.5°C (72.5°F), May is the warmest month.

Heat index

In May, the average heat index is evaluated at a blazing hot 50°C (122°F). On guard: Heat exhaustion and heat cramps are predicted. Heatstroke is a potential hazard with continuous physical effort.
Consider that heat index readings are for situations in the shade and light wind. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are especially crucial for babies and toddlers. Young ones regularly neglect the requirement for rest and fluid replenishment. Thirst is a late stage of dehydration - so, it is necessary to keep hydrated, particularly during extended periods of physical exertion.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.

Humidity

The average relative humidity in May is 70%.

Note: The daily high UV index of 7 in May translates into this advice:
Avoid excessive sunlight. Those with lighter skin may experience burning in less than 20 minutes. Stay in the shade and limit direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is particularly strong. Remember, however, that shade structures may not provide complete protection. Equip yourself with UVA and UVB-filtering sunglasses on clear, sunny days.
