Weather in September
Temperature
The advent of September observes an average high-temperature of a still tropical 88°F (31.1°C), nearly identical to August's 90.1°F (32.3°C). An average low-temperature of 72.7°F (22.6°C) is expected during September.Heat index
In September, the heat index is calculated to be a blistering 105.8°F (41°C). Adopt extra preventive measures, the occurrence of heat cramps and heat exhaustion is likely. Heatstroke may follow extended activity.Know that the heat index computations account for shaded terrains and slight winds. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is the result of factoring in humidity to the air temperature, indicating perceived warmth. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values hold particular significance for children. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. Excessive relative humidity disturbs the body's typical cooling process by reducing evaporation, leading to a decrease in body cooling rate and an increase in the sensation of warmth. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
