Weather in September
Temperature
The onset of September marks an average high-temperature of a still tropical 86.7°F (30.4°C), hardly differing from August's 90.3°F (32.4°C). During September, the temperature tends to dip to an average of 72.7°F (22.6°C) at night.Heat index
During September, the heat index is computed to be a very hot 100.4°F (38°C). Exercise special caution, heat exhaustion and heat cramps are probable. Prolonged activity may induce heatstroke.Take note of the fact that heat index values are based on shaded circumstances with light airflows. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Children frequently do not comprehend the need for rest and hydration. Thirst is an advanced stage of dehydration - staying hydrated, especially during extended physical exercises, is essential.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.
