Weather in September
Temperature
As September takes hold, the average high-temperature is a still hot 88°F (31.1°C), nearly mirroring that of the previous month. The average nighttime temperature lowers to a warm 73.6°F (23.1°C) throughout September.Heat index
The heat index value during September is estimated at a blisteringly hot 105.8°F (41°C). Implement more preventive measures, heat cramps and heat exhaustion are probable. Heatstroke might result from extended activity.Heat index specifics point out values are for conditions of shade and a slight breeze. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', takes into account both air temperature and humidity to illustrate what people actually feel. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
