Weather in September
Temperature
September's arrival signals a moderate reduction in the average high-temperature, easing from a sweltering 96.3°F (35.7°C) in August to a tropical 89.2°F (31.8°C). During September, the temperature tends to dip to an average of 72.5°F (22.5°C) at night.Heat index
September's average heat index is appraised at a blistering 105.8°F (41°C). Incorporate extra safety measures to avoid heat exhaustion and heat cramps. Continuous activity could provoke heatstroke.It is emphasized that the heat index's values are meant for shaded zones with mild winds. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a composite of temperature and humidity figures to convey how warm it feels. 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 highly critical to babies and toddlers. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.

Dodge overexposure. Fair-skinned people can get singed in less than 20 minutes. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is particularly strong, noting that parasols or canopies may not offer total sun protection. By wearing a generously brimmed hat, you can cut UV radiation exposure significantly.
