Weather in September
Temperature
The arrival of September records an average high-temperature of a still tropical 86.9°F (30.5°C), closely related to the 90.5°F (32.5°C) observed in August. September generally records an average low-temperature of 68°F (20°C).Heat index
For most parts of September, the heat index is calculated to be a torrid 98.6°F (37°C). Exercise more precautions, heat cramps and heat exhaustion are potential risks. Continuous activity could precipitate heatstroke.Heat index guidelines indicate values are for light wind scenarios and shaded regions. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', measures the perceived warmth when incorporating the humidity present in the air. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
One of the main methods the human body employs to cool down is by perspiring, as this process allows sweat to evaporate and remove excess heat. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.

Incorporate safeguards and honour sun safety principles. Protection from skin and eye damage is obligatory. To the best of your ability, limit your exposure to the sun between the hours of 10 a.m. and 4 p.m., when UV radiation is at its peak. 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.
