Weather in September
Temperature
A modest decline in the average high-temperature is seen during September, decreasing from a fiery hot 99°F (37.2°C) in August to a tropical 92.7°F (33.7°C). Palmview South experiences a mean temperature of 77.2°F (25.1°C) during September nights.Heat index
For most parts of September, the heat index is calculated to be a blistering 109.4°F (43°C). Attention: Heat exhaustion and heat cramps are anticipated. Prolonged effort can result in heatstroke.Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a composite of temperature and humidity figures to convey how warm it feels. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise 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 human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
