Additionally, the city's weather through September carries hints of transition, harking back to the mild temperatures last seen during April.

Temperature

September's beginning in Bandar Bushehr, Iran, signals an average high-temperature of a still fiery hot 36.6°C (97.9°F), barely different from August's 38.1°C (100.6°F). Bandar Bushehr, during the nights of September, experiences an average temperature drop to a moderately hot 25.1°C (77.2°F).

Heat index

The heat index value during September is appraised at a burning hot 53°C (127.4°F). On guard: Heat exhaustion and heat cramps are predicted. Heatstroke is a potential hazard with continuous physical effort.
Consider that heat index readings are for situations in the shade and light wind. 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', offers an insight into how hot it feels when we factor in moisture content. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
