Weather in September
Temperature
September tends to be the warmest month, with temperatures averaging a daily high of 31.5°C (88.7°F) and a low of 24.4°C (75.9°F).Heat index
The heat index value for September is calculated to be a blistering 42°C (107.6°F). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.Always consider that heat index estimations are for light winds and places in the shade. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is the result of factoring in humidity to the air temperature, indicating perceived warmth. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are extremely significant for babies and toddlers. Youngsters frequently overlook the need for breaks and fluid intake. Thirst is an advanced sign of dehydration - thereby highlighting the importance of keeping hydrated, particularly during long physical activities.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve cooling. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
