Weather in September

The heat index value for September is evaluated at a sweltering 39°C (102.2°F). Take special precautions - heat exhaustion and heat cramps are expected. Heatstroke may occur with lengthy activity.One should be cognizant that the heat index values are tailored for shaded spots and mild winds. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', combines both the air temperature and the humidity level to give a perceived human temperature. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are highly critical to babies and toddlers. Youngsters often neglect the necessity for rest and hydration. Thirst is a sign of advancing dehydration - thus the importance of maintaining hydration, specifically during long-lasting physical activities.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
