Weather in September
Temperature
The arrival of September marks a slight shift to an average high-temperature of a still hot 87.1°F (30.6°C) from August's 91.4°F (33°C). September witnesses an average low-temperature hovering around a refreshing 67.6°F (19.8°C).Heat index
In September, the average heat index is calculated to be a very hot 100.4°F (38°C). Implement enhanced safety actions, heat cramps and heat exhaustion could occur. Sustained activity might result in heatstroke.Consider that heat index readings are for situations in the shade and light wind. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'apparent temperature' or 'feels like', measures the perceived warmth when incorporating the humidity present in the air. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.
