Heat index

The average heat index in March is evaluated at a very hot 37°C (98.6°F). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.
Heat index details are generally centered around shaded locations and a mild breeze. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is an aggregate value of air's warmth and moisture to show the human-felt temperature. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values remain especially vital for babies and toddlers. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.

Stand by precautions and apply sun safety measures. Evading sunburn is of great importance. UV radiation from the Sun is most intense between 10 a.m. and 4 p.m. Try to avoid direct sunlight during this period. On bright days sunglasses that block both UVA and UVB rays should be worn. A hat with a wide brim is extremely helpful, as it can prevent roughly 50% of UV radiation from reaching the eyes. Heads up! UV intensity is amplified by reflections from water and sand.
