Weather in September
Temperature
September ushers in an average high-temperature of a still tropical 34.8°C (94.6°F), aligning closely with the preceding month. During the month of September, an average low-temperature of 25.5°C (77.9°F) is recorded.Heat index
The heat index in September is estimated at a life-threatening hot 47°C (116.6°F). Stay wary: Heat exhaustion and heat cramps are possible. Heatstroke can ensue from extended effort.From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. 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 'apparent temperature' or 'felt air temperature', combines air temperature and relative humidity to represent a human perceived temperature equivalent. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
