Weather in September
Temperature
The arrival of September coincides with an average high-temperature of a moderately hot 29.4°C (84.9°F), indicating a minimal shift from August's 30.8°C (87.4°F). During the nights in September, an average low-temperature of 24.3°C (75.7°F) is observed.Heat index
For most parts of September, the heat index is appraised at a sweltering 37°C (98.6°F). Undertake additional safety actions, risk of heat cramps and heat exhaustion is significant. Persistent activity may induce heatstroke.Heat index details are generally centered around shaded locations and a mild breeze. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is the outcome of merging air's temperature and its humidity metrics. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Kids frequently fail to realize the necessity for resting and hydrating. Thirst is an advanced indication of dehydration - hence, maintaining hydration, especially during extended physical activities, becomes essential.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.

April through September, with an average maximum UV index of 7, are months with the highest UV index. A UV Index reading of 6 to 7 represents a high health vulnerability from exposure to the Sun's UV rays for the average person.Note: The daily high UV index of 7 in September translates into this advice:
Deter overexposure. Protecting against the sun's effects is essential. UV radiation from the Sun is most intense between 10 a.m. and 4 p.m. Try to avoid direct sunlight during this period. For excellent sun protection for the eyes, ears, face, and neck, consider a wide-brim hat.
