Weather in September
Temperature
The average high-temperature in September, at a still tropical 86.9°F (30.5°C), reveals a modest deviation from August's 90.1°F (32.3°C). An average low-temperature of 69.6°F (20.9°C) is common during the nights of September.Heat index
During September, the heat index is computed to be a very hot 100.4°F (38°C). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.Heat index details are generally centered around shaded locations and a mild breeze. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a metric representing the sensation of warmth when air temperature and moisture come together. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Youngsters often neglect the necessity for rest and hydration. Thirst is a sign of advancing dehydration - thus the importance of maintaining hydration, specifically during long-lasting physical activities.
The body's innate mechanism to counteract overheating is through perspiration, as it leverages the cooling effects of sweat evaporation. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
