Weather in September
Temperature
The onset of September marks an average high-temperature of a still tropical 86.5°F (30.3°C), hardly differing from August's 90.7°F (32.6°C). September witnesses an average nighttime temperature of 69.4°F (20.8°C).Heat index
The average heat index in September is calculated to be a very hot 100.4°F (38°C). Undertake extra safety actions, heat cramps and heat exhaustion are expected. Heatstroke may result from lengthy activity.One should consider that heat index numbers are for shaded settings and light wind. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is found by incorporating humidity levels into the air temperature measurement. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
