Weather in September
Temperature
The shift from August to September includes a small decrease in the average high-temperature, from 92.5°F (33.6°C) to a still hot 86.4°F (30.2°C). An average low-temperature of 64.9°F (18.3°C) is recorded in the month of September.Heat index
The average heat index in September is appraised at a sweltering 96.8°F (36°C). Heightened precautions are necessary, heat cramps and heat exhaustion are potential risks. Continuous activity could lead to heatstroke.When assessing, remember that heat index measurements are for light winds and shaded spots. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', takes into account both air temperature and humidity to illustrate what people actually feel. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. 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 extremely significant for children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.

Resist extreme sun exposure. Guarding against solar damage is essential. To the best of your ability, limit your exposure to the sun between the hours of 10 a.m. and 4 p.m., when UV radiation is at its peak. Equip yourself with UVA and UVB-filtering sunglasses on clear, sunny days. Beware! Reflection from snow can magnify the Sun's UV radiation nearly twofold.
