Weather in September
Temperature
The warmest time of the year is September, with temperatures averaging a high of 30.5°C (86.9°F) and a low of 26.5°C (79.7°F).Heat index
Throughout September, the heat index is appraised at a torrid 38°C (100.4°F). Undertake additional precautions, heat cramps and heat exhaustion could happen. Heatstroke could occur from sustained activity.Heat index evaluations are typically in the context of light winds and shaded environments. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', determines the feeling of heat when you account for the relative humidity. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Children often fail to recognize the requirement to rest and rehydrate. Thirst, being a late symptom of dehydration, underlines the importance of maintaining hydration, especially during ongoing physical activities.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.
