Temperature

Heat index

May's heat index is estimated at a fiery hot 39°C (102.2°F). Use additional protective measures, heat cramps and heat exhaustion are possible outcomes. Continuous activity might lead to heatstroke.
One should consider that heat index numbers are for shaded settings and light wind. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'feels like' or 'felt air temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat. An upsurge in relative humidity affects normal body cooling mechanisms 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.

Humidity

The average relative humidity in May is 76%.

Employ safeguards and advocate sun safety protocols. Shielding against skin and eye damage is crucial. Avoid direct exposure to the Sun between 10 a.m. and 4 p.m., the peak period for UV radiation, noting that objects like parasols or canopies might not offer complete sun protection. Loose clothes with a tight weave are optimal for safeguarding yourself against the Sun's rays.
