Weather in September
Temperature
The commencement of September brings an average high-temperature of a still tropical 87.1°F (30.6°C), marking an inconsequential divergence from August. In the month of September, Indiantown records a consistent average low-temperature of 75°F (23.9°C).Heat index
The heat index value for September is calculated to be an extremely hot 104°F (40°C). Implement additional cautionary measures, heat cramps and heat exhaustion could occur. Prolonged activity might induce heatstroke.Heat index data is primarily for areas with shade and subjected to light winds. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', unifies temperature and humidity readings to offer a comprehensive feel of warmth. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
