Weather in September
Temperature
September's onset corresponds with a subtle shift in the average high-temperature, slightly moving from 93.7°F (34.3°C) in August to a still hot 87.1°F (30.6°C). During September, the nighttime temperature averages of 67.3°F (19.6°C).Heat index
September's heat index is estimated at a fiery hot 96.8°F (36°C). Incorporate special precautions, risk of heat exhaustion and heat cramps is substantial. Sustained activity could cause heatstroke.Be aware that heat index ratings are designed for shaded locations and minor breezes. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is achieved by amalgamating air temperature with the relative humidity readings. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Kids frequently ignore the importance of taking a break and rehydrating. Thirst is a late symptom of dehydration - thus, it is crucial to stay hydrated, especially during long-lasting physical activities.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.
