Weather in September
Temperature
The arrival of September is marked by an average high-temperature of a still hot 86°F (30°C), bearing a close resemblance to August. During September, the average low-temperature is recorded at a comfortable 66°F (18.9°C).Heat index
The heat index value for September is appraised at a sweltering 96.8°F (36°C). Incorporate additional safety actions, heat cramps and heat exhaustion are possible. Long-term activity may induce heatstroke.Understand that the heat index values take into account shaded locations and mild winds. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is a single figure representing how weather conditions feel when combining temperature and humidity. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. 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 especially crucial for babies and toddlers. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
