The average heat index in May is appraised at a hot 89.6°F (32°C). Remaining active during long-lasting exposure could cause fatigue, leading to heat cramps.Heat index details are generally centered around shaded locations and a mild breeze. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is found by incorporating humidity levels into the air temperature measurement. 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 hold particular significance for children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
