Heat index

In April, the heat index is evaluated at a blistering 44°C (111.2°F). Keep alert: Heat cramps and heat exhaustion are probable. Heatstroke is a potential danger with continued physical activity.
When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'real feel', melds the effects of warmth and moisture to generate a feeling of heat. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. When body heat isn't effectively managed, risks of dehydration and overheating amplify.

Note: The UV index of 8 during April leads to these advisories:
Protection should always be a priority. Skin and eyes are vulnerable without it. 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. Loose clothes with a tight weave are optimal for safeguarding yourself against the Sun's rays.
