In September, the heat index is calculated to be 84.2°F (29°C). Prolonged exposure combined with continuous activity could lead to exhaustion, and possibly heat cramps.Heat index data is primarily for areas with shade and subjected to light winds. The heat index has the potential to rise by 15 Fahrenheit (8 Celsius) degrees with direct sunshine exposure.
Note: The heat index, also known as 'felt air temperature' or 'feels like', embodies the combination of air temperature and moisture content to illustrate perceived heat. 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. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
