Weather in September
Temperature
September presents an average high-temperature of a still moderately hot 28.8°C (83.8°F), mirroring August. September is noted for a mean low-temperature of 21.5°C (70.7°F).Heat index
September's heat index is calculated to be a tropical 30°C (86°F). One might feel worn out with persistent exposure and activity, resulting in heat cramps.The heat index's values are generally associated with conditions in shade and light breezes. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', binds temperature metrics with humidity values to give a sense of the actual warmth. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are particularly relevant to children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.

Take precautions against overexposure. Fair-skinned people may get burned in less than 20 minutes. Make an effort to avoid direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation, and note that objects like parasols or canopies might not offer full sun protection. Sunglasses that ward off UVA and UVB rays play a pivotal role in reducing solar eye damage.
