Weather in September
Temperature
The advent of September reveals an average high-temperature of a still tropical 87.6°F (30.9°C), showing minimal difference from the prior month. September nights are marked by an average temperature drop to an agreeable 70.7°F (21.5°C).Heat index
Throughout September, the heat index is calculated to be a scorching 104°F (40°C). Adopt additional preventive measures, heat cramps and heat exhaustion are potential outcomes. Prolonged activity may trigger heatstroke.In reference to the heat index, it's for places in shade and with a slight wind. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is an estimation of the warmth sensation when considering humidity levels. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.

Resist overexposure. Safeguarding from solar damage is indispensable. 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. For holistic sun protection encompassing the eyes, ears, face, and neck, a wide-brim hat is key.
