Weather in September
Temperature
The start of September comes with a small reduction in the average high-temperature, subtly receding from a tropical 92.8°F (33.8°C) in August to a moderately hot 84.4°F (29.1°C). The nighttime temperature dips to an enjoyable 64.9°F (18.3°C) on average during September.Heat index
September's heat index is computed to be a tropical 91.4°F (33°C). Heightened precautions are necessary, heat cramps and heat exhaustion are potential risks. Continuous activity could lead to heatstroke.Keep in mind the heat index values are meant for areas in shade and with light wind. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
