Weather in September
Temperature
The transition from August to September sees average high-temperatures adjusting to a still moderately hot 29.5°C (85.1°F), from a not significantly different 28.8°C (83.8°F). During the month of September, the temperature generally drops to a low average of 22.4°C (72.3°F).Heat index
During September, the heat index is appraised at a sweltering 36°C (96.8°F). Implement additional cautionary measures, heat cramps and heat exhaustion could occur. Prolonged activity might induce heatstroke.Be informed that the heat index values are oriented around shady conditions and 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 'feels like' or 'felt air temperature', is the result of factoring in humidity to the air temperature, indicating perceived warmth. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. 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 essentially critical for children. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.
