September weather forecast
Daytona Beach, FL

September weather in Daytona Beach presents a subtle shift from the extreme summer conditions. Though the city witnesses a reduction in rainfall to 4.96" (126mm), it remains one of the year's rainiest periods. Gradual cooling begins to relieve the high summer temperatures, resulting in more comfortable weather. While the occasional rain might persist, the month is well compensated by the extended hours of sunshine. Inching towards October, the city starts noticing shorter daylight hours and slightly cooler sea temperatures.

Temperature

Entering September, Daytona Beach's average high-temperature reads a still tropical 86.2°F (30.1°C), indicating a close resemblance to the previous month's climate. Nighttime temperature lowers to an average of 75.9°F (24.4°C) in September.

Heat index

For most parts of September, the heat index is evaluated at a very hot 98.6°F (37°C). Exercise heightened safety, heat cramps and heat exhaustion are probable. Persistent activity may provoke heatstroke.
The heat index's values are generally associated with conditions in shade and light breezes. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.

Humidity

Refrain from overexposure. Fair-skinned individuals could burn in under 20 minutes. Limit direct sun exposure and seek shade between 10 a.m. and 4 p.m., the time of the most intense UV radiation, noting that shade structures may not provide total sun protection. Prioritize a wide-brim hat for comprehensive sun defense for your face, neck, eyes, and ears. Heads up! UV intensity is amplified by reflections from water and sand.
