Weather in September
Temperature
The arrival of September is marked by an average high-temperature of a still tropical 87.8°F (31°C), bearing a close resemblance to August. An average low-temperature of 67.6°F (19.8°C) is anticipated throughout the nights during September.Heat index
The heat index value during September is appraised at a very hot 102.2°F (39°C). Adopt heightened preventive measures, heat exhaustion and heat cramps are probable. Persistent activity could lead to heatstroke.Take note of the fact that heat index values are based on shaded circumstances with light airflows. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.
