The average heat index in March is appraised at an extremely hot 41°C (105.8°F). Take special precautions - heat exhaustion and heat cramps are expected. Heatstroke may occur with lengthy activity.
For clarity, heat index numbers account for light winds and areas under shade. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', melds the effects of warmth and moisture to generate a feeling of heat. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.

For excellent sun protection for the eyes, ears, face, and neck, consider a wide-brim hat.
