Weather in September

September's arrival comes with a mild decrease in the average high-temperature, moving subtly from a tropical 91.6°F (33.1°C) in August to a warm 83.5°F (28.6°C). An average minimum temperature of 64.4°F (18°C) is recorded during the month of September.Heat index

Fatigue might occur with continuous exposure and activity, potentially causing heat cramps.When assessing, remember that heat index measurements are for light winds and shaded spots. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', combines both the air temperature and the humidity level to give a perceived human temperature. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Young ones regularly neglect the requirement for rest and fluid replenishment. Thirst is a late stage of dehydration - so, it is necessary to keep hydrated, particularly during extended periods of physical exertion.
