Heat index

March's heat index is evaluated at a torrid 35°C (95°F). Undertake enhanced precautions, heat exhaustion and heat cramps are possible risks. Continuous activity could trigger heatstroke.
It is crucial to understand that heat index figures are for shade and gentle wind conditions. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', ties air temperature with relative humidity to produce the perceived temperature sensation. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to 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 body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.

January and March, with an average relative humidity of 65%, are the least humid months.

Refrain from overexposure. Fair-skinned individuals could burn in under 20 minutes. It's important to stay in the shade and limit exposure to the sun from 10 a.m. to 4 p.m., when UV radiation is most intense, although remember that shade structures may not provide full sun protection. Safeguard your eyes, ears, and face from sun rays with the aid of a wide-brim hat. Notice! The Sun's UV exposure elevates with sand and water reflections.
