Weather in September
Temperature
Entering September, the average high-temperature is recorded at a still moderately hot 28.7°C (83.7°F), exhibiting a minimal shift from August's 27.9°C (82.2°F). Throughout September, the nighttime temperature averages to a still warm 23.4°C (74.1°F).Heat index
The average heat index in September is estimated at a fiery hot 35°C (95°F). Exercise special caution, heat exhaustion and heat cramps are probable. Prolonged activity may induce heatstroke.In reference to the heat index, it's for places in shade and with a slight wind. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. 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 especially crucial for babies and toddlers. Juveniles often do not understand the need to recuperate and rehydrate. Thirst is a delayed symptom of dehydration - hence, it is vital to maintain hydration, particularly during ongoing physical activities.
One of the main methods the human body employs to cool down is by perspiring, as this process allows sweat to evaporate and remove excess heat. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.

Beware of overexposure. Fair-skinned individuals risk burning in less than 20 minutes. During the period from 10 a.m. to 4 p.m., UV radiation is highest. Try to avoid direct sunlight during these hours. Sunglasses that ward off UVA and UVB rays play a pivotal role in reducing solar eye damage.
