Heat index

Throughout May, the heat index is evaluated at a blistering 40°C (104°F). Implement additional safety measures to avoid heat cramps and heat exhaustion. Persistent activity might trigger heatstroke.
Regarding the heat index, one should be aware it's determined by shaded settings and mild winds. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a metric representing the sensation of warmth when air temperature and moisture come together. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.

Note: A daily maximum UV index of 6 in May translates into the following instructions:
Stay clear of intense sun exposure. Solar protection is of utmost significance. Seek shade and limit direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Keep in mind that shade structures like parasols or canopies do not offer complete sun protection. Your best bet for sun defense on the face, eyes, and neck is a hat with a wide brim.
