Weather in September

September, the first month of the autumn in Cumpressco, is still a hot month, with an average temperature fluctuating between 88.2°F (31.2°C) and 73.8°F (23.2°C).

Temperature

The average high-temperature in September, at a still hot 88.2°F (31.2°C), reveals a modest deviation from August's 90.1°F (32.3°C). Nighttime temperatures in September average to a moderately hot 73.8°F (23.2°C).

Heat index

The heat index for September is computed to be a blisteringly hot 105.8°F (41°C). Exercise more precautions, heat cramps and heat exhaustion are potential risks. Continuous activity could precipitate heatstroke.
When assessing, remember that heat index measurements are for light winds and shaded spots. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'feels like' or 'real feel', binds temperature metrics with humidity values to give a sense of the actual warmth. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
