Weather in September
Temperature
During the shift to September, a minor reduction in average high-temperature is observed, shifting from a torrid 98.1°F (36.7°C) in August to a hot 90.3°F (32.4°C). During September, the temperature tends to dip to an average of 73°F (22.8°C) at night.Heat index
In September, the heat index is appraised at a scorching 104°F (40°C). Exercise increased caution, heat cramps and heat exhaustion are potential hazards. Continuous activity could lead to heatstroke.Note that heat index values are valued for light wind and location in the shade. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', represents the fusion of temperature and moisture in the air to suggest how warm it feels. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.

Escape overexposure. People with light skin may incur burns in fewer than 20 minutes. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is particularly strong, noting that parasols or canopies may not offer total sun protection. Fend off the sun's harsh rays with appropriate clothing, a wide-brim hat, and UV-protective sunglasses.
