The beginning of May records an average high-temperature of a still tropical 31.3°C (88.3°F), marking a negligible difference from April's 34°C (93.2°F). An average low-temperature of 23.5°C (74.3°F) is noted during the nights in May.

Heat index

The heat index value during May is appraised at a blistering 43°C (109.4°F). Keep guard: Heat cramps and heat exhaustion are likely. Continued activity increases the risk of heatstroke.
Always consider that heat index estimations are for light winds and places in the shade. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is found by incorporating humidity levels into the air temperature measurement. A person's impression of weather can be swayed by numerous aspects, among them metabolic variations, pregnancy, and activity levels. You should know that direct sun exposure can heighten weather effects, potentially elevating the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.

The average relative humidity in May is 83%.

Note: A maximum UV index of 7 in May translates into the following recommendations:
Avert overexposure. Light-skinned people might 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. Safeguard your eyes, ears, and face from sun rays with the aid of a wide-brim hat.
