Heat index

September's heat index is calculated to be a blazing hot 45°C (113°F). Be cautious: Heat exhaustion along with heat cramps are predicted. Heatstroke is a possible consequence of continuous physical effort.
From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', combines air temperature and relative humidity to represent a human perceived temperature equivalent. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Kids often lack the knowledge about the necessity to take breaks and consume liquids. Thirst, as a late symptom of dehydration, necessitates the maintenance of hydration, particularly during enduring physical activities.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.

Humidity

The average relative humidity in September is 84%.
