Weather in September

The commencement of September notes an average high-temperature of a still hot 86.9°F (30.5°C), exhibiting little difference from the previous month. The temperature dips to an average of 73.4°F (23°C) during September nights.Heat index
Throughout September, the heat index is calculated to be a sweltering 100.4°F (38°C). Incorporate additional safety actions, heat cramps and heat exhaustion are possible. Long-term activity may induce heatstroke.Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. It is noteworthy that being in direct sunlight can enhance the weather's impact, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Youngsters often neglect the necessity for rest and hydration. Thirst is a sign of advancing dehydration - thus the importance of maintaining hydration, specifically during long-lasting physical activities.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
