Daytona Beach has a humid subtropical climate , which is typical of the Gulf and South Atlantic states. As is typical of much of Florida, there are two seasons in Daytona Beach; the warmer, wetter season (late May through October) and the cooler and drier season (November through April).
In summer, temperatures are relatively stable and there is an average of only 8 days annually with a maximum at or above 95 °F (35 °C); the last 100 °F (38 °C) reading was seen on August 2, 1999. The Bermuda High pumps hot and unstable tropical air from the Bahamas and Gulf of Mexico, resulting in daily, but brief thundershowers. This results in the months of June through September accounting for a majority of the average annual rainfall of 51.25 in (1,302 mm).
In winter, Daytona Beach has weather conditions typical of other cities on the Florida peninsula. On average, the coolest month is January, with a normal monthly mean temperature of 58.8 °F (14.9 °C). Occasional cold fronts can bring freezes, which from 1991 to 2020 were seen on an average of 3.0 nights annually; however, minima below 25 °F (−4 °C) are very rare, and were last seen on December 28, 2010. Like much of Florida, Daytona Beach often can be very dry in late winter and early spring, and brush fires and water restrictions can be an issue.
Official record temperatures range from 15 °F (−9 °C) on January 21, 1985, up to 102 °F (39 °C) on July 15, 1981, and June 24, 1944; the record cold daily maximum is 33 °F (1 °C) on Christmas 1985, while, conversely, the record warm daily minimum is 82 °F (28 °C) on September 1 and 10–11, 2008 and August 25, 2020. Annual rainfall has ranged from 31.36 in (797 mm) in 2006 and 1956, up to 79.29 in (2,014 mm) in 1953. The most rainfall to have occurred in a calendar day was 12.85 in (326 mm) on October 10, 1924, which contributed to 24.82 in (630 mm) of rain that fell that month, the most of any calendar month.
