Weather in September
Temperature
September's advent presents an average high-temperature of a still tropical 86.7°F (30.4°C), indicating a slight variation from the conditions of the previous month. The average temperature drops to an agreeable 70.7°F (21.5°C) during the night in the month of September.Heat index
During September, the heat index is computed to be a torrid 102.2°F (39°C). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.Understand that the heat index values take into account shaded locations and mild winds. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'feels like' or 'apparent temperature', unifies temperature and humidity readings to offer a comprehensive feel of warmth. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Awareness of direct sun exposure is crucial as it has the potential to heighten the weather's effects, pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.
