Weather in September
Temperature
September's weather displays an average high-temperature of a still hot 88°F (31.1°C), slightly varied from August's 91.9°F (33.3°C). The average low-temperature, in September, is a comfortable 67.5°F (19.7°C).Heat index
For most parts of September, the heat index is calculated to be a sweltering 102.2°F (39°C). Ensure heightened precautions, risk of heat cramps and heat exhaustion is significant. Sustained activity could provoke heatstroke.It is worth noting that heat index values are gauged for conditions in the shade and light breezes. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', blends air temperature and moisture content to represent the felt temperature to humans. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Kids often lack the knowledge about the necessity to take breaks and consume liquids. Thirst, as a late symptom of dehydration, necessitates the maintenance of hydration, particularly during enduring physical activities.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.
