Weather in September
Temperature
The beginning of September reveals an average high-temperature of a still tropical 87.1°F (30.6°C), showing minimal deviation from the previous month. The average temperature during September nights dips to a comfortable 66.9°F (19.4°C).Heat index
The average heat index in September is computed to be a very hot 98.6°F (37°C). Undertake extra safety actions, heat cramps and heat exhaustion are expected. Heatstroke may result from lengthy activity.Take note of the fact that heat index values are based on shaded circumstances with light airflows. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. Greater relative humidity lessens the rate of evaporation, thus decreasing the body's heat dispersal, which gives rise to a sensation of overheating. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.

Fend off overexposure. Sun protection is vital. Remember that UV radiation from the Sun is strongest between 10 a.m. and 4 p.m. Make an effort to limit direct sun exposure during this time. A wide-brim hat offers excellent sun protection for the eyes, ears, face, and neck. Sunglasses with UVA and UVB protection significantly reduce eye damage from sun exposure.
