Weather in September
Temperature
The onset of September results in a small decrease in the average high-temperature, moderately receding from a very hot 35.3°C (95.5°F) in August to a hot 32.3°C (90.1°F). Throughout September, an average nighttime temperature of 20.6°C (69.1°F) is experienced.Heat index
September's mean heat index is evaluated at a fiery hot 37°C (98.6°F). Take more preventive steps, risk of heat exhaustion and heat cramps is elevated. Long activity may culminate in heatstroke.It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a numerical representation of warmth when taking temperature and moisture levels into account. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. You should know that direct sun exposure can heighten weather effects, potentially elevating the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Young ones often ignore the need to take a break and drink fluids. Thirst is a late-stage symptom of dehydration - hence, maintaining hydration, particularly during extended physical activities, is crucial.
Sweat evaporation, driven by perspiration, is the method the human body uses to rid itself of excessive warmth. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. As body temperatures escalate without effective heat release, one might face dehydration threats.
