Weather in September
Temperature
In September, the average high-temperature registers at a still hot 87.1°F (30.6°C), nearly identical to August's 92.1°F (33.4°C). An average low-temperature of 67.5°F (19.7°C) marks the nights throughout September.Heat index
For September, the heat index is estimated at a torrid 98.6°F (37°C). Adopt heightened preventive measures, heat exhaustion and heat cramps are probable. Persistent activity could lead to heatstroke.Be advised, the heat index considers values for conditions in shade and with a light breeze. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a single figure representing how weather conditions feel when combining temperature and humidity. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.

However, keep in mind that shade structures may not provide full sun protection. In the presence of strong sunlight, it's crucial to wear sunglasses that ward off UVA and UVB rays.
