Weather in September
Temperature
The advent of September brings an average high-temperature of a still warm 29.9°C (85.8°F), almost the same as the preceding month. During September, the temperature is averaged to a low of 24.1°C (75.4°F) at night.Heat index
September's mean heat index is estimated at a sweltering 36°C (96.8°F). Ensure extra safety steps, heat exhaustion and heat cramps are likely. Long activity might lead to heatstroke.The standards for the heat index are set for locations in shade and under light breezes. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', binds temperature metrics with humidity values to give a sense of the actual warmth. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant 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.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
