Sebastian Inlet • Surf Spot Statistics

Sebastian Inlet is a classic East-Central Florida setup: an east-northeast exposure that catches Atlantic energy sweeping in from the Bahamas and beyond, but one that is also constantly at the mercy of the prevailing wind. The surf year builds through autumn, peaks in winter, then fades fast when the Bermuda High takes charge in late spring.

Best Surf Season (October - March)

For Sebastian Inlet, the meat of the surf year runs from October through March. The east-northeast-facing break gets a steady diet of E, ENE and NE swell as extratropical storms, Nor'easters and cold fronts energize the western Atlantic. Average wave heights sit in the 2.5-3.5ft (0.8-1.0m) range and periods cluster in the punchy 8-9s sweet spot, with the most reliable combination of size and clean wind in November, December and January. The negative phase of the NAO can park blocking high pressure over Greenland, shunting more storms down the Eastern Seaboard and delivering better ENE/NE swell with the right post-frontal W/SW wind. When a strong low lingers off the Carolina coast and a cold front is approaching, the inlet can light up with chest-to-head-high plus sets and offshore west wind.

Fair Surf Season (April - May & September)

The shoulder months are about transition. April still sees leftover winter energy, but the trade wind machine begins to spin up, bringing more E/ESE wind and making clean conditions harder to find. May is often small, groveling and onshore as the Bermuda High settles in, though occasional late-season frontal pulses can still deliver a fun NE swell. September, on the other hand, marks the beginning of the Atlantic tropical season's prime time: the average wave period jumps to 9.0s and any passing hurricane or tropical wave can send ENE/E swell into the inlet. The catch is that E/NE winds often accompany these systems, so quality is a roll of the dice.

Low Surf Season (June - August)

Summer is the slow season at Sebastian Inlet. The wave rose becomes dominated by E and ESE windswell, average heights drop to 1.5-2ft (0.5-0.6m), and periods slip into the 7-8s range. The Bermuda High pumps persistent east and southeast trade winds straight onshore, leaving the lineup chopped and lumpy; favorable wind is only present 13-15% of the time. Water temperatures climb to a bath-like 27.7-29°C and afternoon thunderstorms are frequent. Unless a tropical cyclone tracks through the western Atlantic, surfers are left riding knee-high micro waves between summer showers.
