Weather in September
Temperature

During September, the heat index is evaluated at a blistering 40°C (104°F). Take special precautions - heat exhaustion and heat cramps are expected. Heatstroke may occur with lengthy activity.Regarding the heat index, one should be aware it's determined by shaded settings and mild winds. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', reflects the feeling of heat when considering both air temperature and humidity. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital 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.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.
