Heat index

Throughout May, the heat index is appraised at a sweltering 39°C (102.2°F). Additional precautions are required to avert heat cramps and heat exhaustion. Persistent activity may culminate in heatstroke.
One should consider that heat index numbers are for shaded settings and light wind. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', binds temperature metrics with humidity values to give a sense of the actual warmth. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.

In May, the average relative humidity is 79%.

UV index

Note: In May, the maximum UV index of 6 translates into these guidelines:
Eschew overexposure. Those with light skin may suffer burns in fewer than 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. To cut down UV radiation exposure by about half, sport a wide-brim hat.
