Heat index

Throughout May, the heat index is evaluated at a fiery hot 100.4°F. Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.
Be informed that the heat index values are oriented around shady conditions and gentle breezes. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', evaluates the perceived heat by adding the effect of moisture in the air. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly relevant to babies and toddlers. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
