Heat index

March's average heat index is calculated to be a torrid 39°C (102.2°F). Implement additional safety measures to avoid heat cramps and heat exhaustion. Persistent activity might trigger heatstroke.
Be advised, the heat index considers values for conditions in shade and with a light breeze. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', gauges the sensation of temperature factoring in the air's moisture content. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.
