Weather in September
Temperature
The arrival of September marks a slight shift to an average high-temperature of a still torrid 35.2°C (95.4°F) from August's 37.6°C (99.7°F). In September, the temperature sees a substantial plunge from daytime highs to a low average of 20.7°C (69.3°F).Heat index
For most parts of September, the heat index is evaluated at an extremely hot 44°C (111.2°F). Keep wary: Heat cramps along with heat exhaustion are expected. Heatstroke is a possible outcome of ongoing activity.Take note of the fact that heat index values are based on shaded circumstances with light airflows. The heat index has the potential to rise by 15 Fahrenheit (8 Celsius) degrees with direct sunshine exposure.
Note: The heat index, also known as 'apparent temperature' or 'feels like', takes into account both air temperature and humidity to illustrate what people actually feel. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. As body temperatures escalate without effective heat release, one might face dehydration threats.
