Weather in September
Temperature
September's arrival subtly correlates with a reduction in the average high-temperature, down from a very hot 95.5°F (35.3°C) in August to a tropical 90°F (32.2°C). An average low-temperature of 74.1°F (23.4°C) marks the nights throughout September.Heat index
The heat index value during September is appraised at a blisteringly hot 107.6°F (42°C). Heightened precautions are necessary, heat cramps and heat exhaustion are potential risks. Continuous activity could lead to heatstroke.Heat index values are typically calculated for conditions of shade and a light breeze. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', quantifies the warmth felt when relative humidity is considered. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are extremely significant for babies and toddlers. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.

May through September, with an average maximum UV index of 7, are months with the highest UV index. A UV Index value of 6 to 7 symbolizes a high health risk from exposure to the Sun's UV rays for ordinary individuals.Note: In September, an average UV index of 7 transforms into the following instructions:
Take precautions against overexposure. Fair-skinned people may get burned in less than 20 minutes. Limit direct sun exposure especially between 10 a.m. and 4 p.m., when UV radiation is at its peak. However, keep in mind that shade structures may not provide full sun protection. Sun-protective clothing, a long-sleeved shirt and pants, a wide-brimmed hat, and UVA and UVB-blocking sunglasses are particularly helpful in blocking UV radiation's harmful effects.
