Weather in September
Temperature
September's arrival subtly correlates with a reduction in the average high-temperature, down from a fiery hot 96.4°F (35.8°C) in August to a hot 88.7°F (31.5°C). During September, the temperature is averaged to a low of 70.7°F (21.5°C) at night.Heat index
The heat index value for September is estimated at a fiery hot 100.4°F (38°C). Heightened precautions are necessary, heat cramps and heat exhaustion are potential risks. Continuous activity could lead to heatstroke.Heat index details are generally centered around shaded locations and a mild breeze. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', provides an understanding of perceived warmth by combining temperature and relative humidity. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
