Weather in September
Temperature
Transitioning into September, Kaplan records an average high-temperature of a still hot 86.5°F (30.3°C), almost identical to August's 89.8°F (32.1°C). Kaplan records a mean low-temperature of 71.2°F (21.8°C) in September.Heat index
The heat index value for September is estimated at a sweltering 100.4°F (38°C). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.Keep in mind the heat index values are meant for areas in shade and with light wind. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', integrates the air's temperature and its humidity to showcase the felt temperature by people. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. 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.
Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.
