Weather in September
Temperature
September's advent notes a subtle adjustment in average high-temperature to a still tropical 86.7°F (30.4°C) from August. Nighttime temperatures in September average to an enjoyable 66.4°F (19.1°C).Heat index
September's average heat index is computed to be a fiery hot 98.6°F (37°C). Exercise heightened safety, heat cramps and heat exhaustion are probable. Persistent activity may provoke heatstroke.Be informed that the heat index values are oriented around shady conditions and gentle breezes. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a value derived by merging air temperature with the humidity to convey how the climate feels. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young ones often do not realize the necessity to rest and replenish their fluids. Thirst is a delayed indication of dehydration - keeping hydrated, particularly in prolonged physical activity, is crucial.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. Rising body temperatures due to excess heat retention could signify impending heat disorders.
