Weather in September
Temperature
September's onset records an average high-temperature of a hot 30.6°C (87.1°F), a near match to August's 29.8°C (85.6°F). During the month of September, an average low-temperature of 20.2°C (68.4°F) is recorded.Heat index
September's average heat index is evaluated at a scorching 40°C (104°F). Take greater precautions, heat exhaustion and heat cramps may be expected. Heatstroke could result from lengthy activity.It is worth noting that heat index values are gauged for conditions in the shade and light breezes. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a value derived by merging air temperature with the humidity to convey how the climate feels. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. 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 are particularly meaningful for babies and toddlers. Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
