Weather in September
Temperature
September, having an average high-temperature of 32.4°C (90.3°F) and an average low-temperature of 22.6°C (72.7°F), is the warmest month.Heat index
September's average heat index is appraised at a blistering 40°C (104°F). Adopt additional preventive measures, heat cramps and heat exhaustion are potential outcomes. Prolonged activity may trigger heatstroke.Be advised, the heat index considers values for conditions in shade and with a light breeze. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', blends air temperature and moisture content to represent the felt temperature to humans. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Juveniles are regularly less conscious of the need to recuperate and rehydrate. Thirst is a tardy symptom of dehydration - hydration, especially during lengthy physical activities, should be maintained.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. As body temperatures escalate without effective heat release, one might face dehydration threats.
