Weather in September
Temperature
The yearly lowest temperatures occur in January and September, averaging a high-temperature of 30.7°C (87.3°F).Heat index
The heat index value during September is computed to be a blistering 41°C (105.8°F). Adopt heightened preventive measures, heat exhaustion and heat cramps are probable. Persistent activity could lead to heatstroke.Understand that the heat index values take into account shaded locations and mild winds. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', joins air temperature with relative humidity to produce a temperature perception for humans. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

February through June, August through December, with an average maximum UV index of 7, are months with the highest UV index. A UV Index of 6 to 7 symbolizes a high health vulnerability from unprotected exposure to Sun's UV rays for the average person.Note: The maximum daily UV index, 7 in September, converts into the following recommendations:
Evade overexposure. Individuals with fair skin risk burning in under 20 minutes. Stay in the shade and limit direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is particularly strong. Remember, however, that shade structures may not provide complete protection. Equip yourself with UVA and UVB-filtering sunglasses on clear, sunny days.
