Heat index

The heat index for April is computed to be a very hot 39°C (102.2°F). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.
Remember that heat index calculations are made for conditions in the shade with light wind. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is the outcome of merging air's temperature and its humidity metrics. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.

Avert overexposure. Light-skinned people might experience burning in less than 20 minutes. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is particularly strong, noting that parasols or canopies may not offer total sun protection. Fend off the sun's harsh rays with appropriate clothing, a wide-brim hat, and UV-protective sunglasses. Attention! UV radiation is markedly stronger with water and sand reflections.
