Flagler Beach - surf spot statistics

Best Surf Season (October – March)

The North Atlantic winter machine fires up in October, delivering a steady diet of medium-period ENE and NE swell to Flagler Beach. Average wave heights hold in the 0.7–0.8 m range with periods climbing toward 8.5 s, offering plenty of rideable, punchy surf. Offshore wind potential peaks during these months as strong cold fronts sweep through the Southeast, shifting winds to the SSW–W quadrant. December and January are the sweet spot, with ideal wind occurring 28–30% of the time—often in the wake of a departing low. When the alignment of a solid NE groundswell and a clean westerly wind comes together, Flagler delivers fun, rippable waves with occasional pumping sets.

Fair Surf Season (April – May & September)

Spring and early fall are transitional periods. April and May see average swell heights drop to 0.6 m and period slip slightly, while the percentage of ideal wind falls to 13–22%. The dominant swell shifts eastward, with E and ESE pulses becoming more common—these are often weaker and more windswell in nature. September offers a promising ramp-up in swell energy (periods near 8.9 s) as early-season hurricanes and nor’easters begin to stir the Atlantic, but the wind is still predominantly onshore from the NE–E, keeping the window for clean conditions narrow. Expect fun, groveling waves on the better days, but patience is required.

Low Surf Season (June – August)

Summer brings the worst of Flagler Beach’s surf year. Average swell height bottoms out at 0.4–0.5 m, and the wave period hovers around 8 s, but 80–90% of the energy arrives from the ESE–SE quadrant—completely unfavorable for this ENExposed beach. The wind is persistently onshore from the E–SE, with ideal offshore flow occurring only 7–8% of the time. The result is small, choppy, messy conditions that are rarely worth the paddle out. Occasional distant hurricane swell can sneak in, but it’s usually too weak or contaminated by local onshore wind. This is the time to focus on gear maintenance or other hobbies until autumn returns.

November: Peak Season Potential

November is arguably the best month of the year at Flagler Beach. Average swell height peaks at 0.8 m, period a solid 8.5 s, and ideal wind climbs to 22%. The swell mix is well-balanced: NE (18.5%), ENE (26.6%), and E (25.4%) all contribute, with NE and ENE delivering the most consistent 1–1.5 m and 1.5–2 m sets. The percentage of 1–1.5 m surf from NE and ENE is 3.9% and 4.7% respectively, while pumping 1.5–2 m appears 1.0% and 1.4%. The wind distribution shows a healthy dose of westerly components: WSW, W, WNW (3.8%, 3.9%, 4.6%), plus a strong showing of post-frontal N–NW flow. This month sees the highest average swell heights and the most reliable windows of offshore wind. When a strong high pressure system builds over the Midwest after a cold front, a classic pattern develops: clean west wind all day and a steady NE swell running. The combination of long-period pulse and groomed conditions can produce overhead, rippable surf—definitely the month to clear your schedule.
