Weather in September

The first month of the autumn, September, is also a moderately hot month in Lighthouse Point, Florida, with an average temperature fluctuating between 80.2°F (26.8°C) and 85.3°F (29.6°C).

The advent of September denotes an average high-temperature of a warm 85.3°F (29.6°C), subtly different from August's 87.1°F (30.6°C). Recording a slight decline in temperature during the nights, Lighthouse Point's September temperatures average at 80.2°F (26.8°C).

Heat index

September's average heat index is computed to be a torrid 95°F (35°C). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.
Keep in mind the heat index values are meant for areas in shade and with light wind. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
Perspiring is a crucial mechanism for the human body, allowing it to release excessive warmth through evaporating sweat. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
