Weather in September
Temperature
The beginning of September brings a slight decrease in the average high-temperature, transitioning from a tropical 93.9°F (34.4°C) in August to a still hot 86.2°F (30.1°C). Nighttime temperature dips to a mean of 67.5°F (19.7°C) during September.Heat index
In September, the average heat index is calculated to be a very hot 95°F (35°C). Ensure extra safety steps, heat exhaustion and heat cramps are likely. Long activity might lead to heatstroke.Note that heat index values are valued for light wind and location in the shade. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'feels like' or 'felt air temperature', evaluates the perceived heat by adding the effect of moisture in the air. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
When faced with excessive heat, the human body begins to perspire, utilizing the cooling benefits of sweat evaporation. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.

Adopt measures and apply sun safety strategies. Shielding from skin and eye damage is necessary. Attempt to stay under shade and limit exposure to the Sun between 10 a.m. and 4 p.m., when UV radiation is at its peak. Remember, devices such as parasols or canopies might not provide complete sun protection. For a sun-safe wardrobe, go for clothes that are tightly woven and generously sized.
