Weather in September
Temperature
September's arrival brings an average high-temperature of a still hot 30.1°C (86.2°F), slightly deviating from August's 30.3°C (86.5°F). September nights register a minor temperature decline, steadying at a warm 25.4°C (77.7°F).Heat index
Throughout September, the heat index is estimated at a very hot 39°C (102.2°F). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.Always consider that heat index estimations are for light winds and places in the shade. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
