Weather in September
Temperature
The arrival of September denotes a barely perceptible change in the average high-temperatures to a still tropical 86.5°F (30.3°C) from August's 90.9°F (32.7°C). Nighttime temperatures hover around an average low of 67.1°F (19.5°C) in September.Heat index
In September, the average heat index is calculated to be a sweltering 96.8°F (36°C). Incorporate special precautions, risk of heat exhaustion and heat cramps is substantial. Sustained activity could cause heatstroke.Records show heat index calculations are tailored for shaded regions and mild winds. With exposure to direct sunlight, the heat index may be increased by up to 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 perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. 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.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
