For September, the heat index is estimated at a hot 86°F (30°C). Exposure and extended activity could potentially cause a state of fatigue and lead to heat cramps.Keep in mind the heat index values are meant for areas in shade and with light wind. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'feels like' or 'real feel', melds the effects of warmth and moisture to generate a feeling of heat. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values remain especially vital for babies and toddlers. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
