Weather in September

September, the first month of the autumn in Mart, is also a hot month, with an average temperature varying between 70.7°F (21.5°C) and 88.7°F (31.5°C).

Temperature

Mart's weather subtly changes with the onset of September, barely falling from a very hot 96.4°F (35.8°C) in August to a tropical 88.7°F (31.5°C). During September, Mart experiences an average low-temperature of 70.7°F (21.5°C) at night.

Heat index

September's average heat index is appraised at a sweltering 100.4°F (38°C). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.
The heat index's values are generally associated with conditions in shade and light breezes. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', blends air temperature and moisture content to represent the felt temperature to humans. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
