Weather in September
Temperature
In September, the average high-temperature marginally drops from a very hot 95.4°F (35.2°C) in August to a tropical 88.7°F (31.5°C). In September, the temperature drops to an average of 68.4°F (20.2°C) at night.Heat index
Throughout September, the heat index is estimated at a sweltering 102.2°F (39°C). Take more preventive steps, risk of heat exhaustion and heat cramps is elevated. Long activity may culminate in heatstroke.Heat index details are generally centered around shaded locations and a mild breeze. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'real feel' or 'felt air temperature', gauges the sensation of temperature factoring in the air's moisture content. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.

Avert overexposure. Light-skinned people might experience burning in less than 20 minutes. Avoid direct exposure to the Sun between 10 a.m. and 4 p.m., the peak period for UV radiation, noting that objects like parasols or canopies might not offer complete sun protection. Employ a hat with a wide brim for robust protection, cutting UV exposure by half. Remember to consider! The UV radiation from the Sun can be intensified nearly twice by the reflection of snow.
