Weather in September
Temperature
The onset of September brings with it an average high-temperature of a hot 30.2°C (86.4°F), showing a negligible variation from the month before. During the nights in September, the temperature averages to a refreshing 19.5°C (67.1°F).Heat index
September's heat index is appraised at a very hot 37°C (98.6°F). Implement additional safety measures to avoid heat cramps and heat exhaustion. Persistent activity might trigger heatstroke.In the scope of the heat index, its values resonate with shade and light wind conditions. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', combines both the air temperature and the humidity level to give a perceived human temperature. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. 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.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. 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. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.

Take precautions against overexposure. Fair-skinned people may get burned in less than 20 minutes. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is at its strongest, and remember that parasols or canopies do not offer full protection. Stay sun-safe with clothing that is both closely woven and worn loosely.
