Heat index

For May, the heat index is estimated at a blisteringly hot 40°C (104°F). Take special precautions - heat exhaustion and heat cramps are expected. Heatstroke may occur with lengthy activity.
Regarding the heat index, one should be aware it's determined by shaded settings and mild winds. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', evaluates the perceived heat by adding the effect of moisture in the air. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. With an abundance of moisture present in the air, the process of evaporation becomes less effective, and the body fails to cool down as it should, leading to the sensation of overheating. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.

Prevent overexposure. Protection from the sun's harmful effects is needed. UV radiation from the sun is at its strongest between 10 a.m. and 4 p.m. Try to limit direct exposure during these hours. By wearing a generously brimmed hat, you can cut UV radiation exposure significantly. Warning! Reflective surfaces like sand and water amplify the Sun's UV radiation.
