Weather in September
Temperature
With average temperatures fluctuating between a high of 32.1°C (89.8°F) and a low of 22.8°C (73°F), September stands out as the warmest month.Heat index
In September, the average heat index is calculated to be an extremely hot 40°C (104°F). Ensure additional precautions, heat exhaustion and heat cramps may be expected. Heatstroke could occur from sustained activity.When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is an aggregate value of air's warmth and moisture to show the human-felt temperature. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Children frequently underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
