7 - 11 - surf spot statistics

Best Surf Season (December - February)

The heart of winter brings the most consistent and quality surf to 7-11. Strong extratropical cyclones track across the North Atlantic, sending powerful, long-period swell pulses from the eastern quadrant – exactly where this beach shines. Average wave heights hold steady around 1.2m with periods climbing to 7.0-7.3s, and the wind plays ball nearly half the time, with dominant offshore flows out of the W, WNW, and NW that groom the lines to perfection. When a cold front sweeps through and the skies clear, expect punchy, rideable waves with excellent shape. This is the prime window for experienced surfers to score.

Fair Surf Season (March - May & October - November)

The shoulder months offer a mixed bag of opportunity. As winter loosens its grip in spring, swell heights ease to 0.9-1.1m and periods shorten, while autumn sees a ramp-up in energy from early-season storms. Wind patterns become more fickle – the ideal offshore flow drops to 35-45%, and southerly components creep in, often ruining the surface. However, transitional periods between weather systems can deliver unexpected gems: a late-season nor’easter in March or a tropical low in October can flip the script, producing clean, lined-up sets. Patience and a flexible schedule are key.

Low Surf Season (June - September)

Summer throttles back the energy at 7-11. Average swell heights bottom out at 0.8m and periods fall to a weak 6.7-7.2s, yielding small, choppy conditions. The dominant swell source switches to the south – while SSE and SE swells are technically in the optimal window, they often arrive with onshore winds from the SSW-SW quadrant, creating bumpy, disorganized waves. Although ideal wind percentages hover around 41-46%, the lack of real swell size and power means only the most dedicated longboarders or beginners will find fun on rare glassy mornings. It’s a time for cruising and avoiding the summer crowds that swarm the beach.

February: Consistent Cold Swell

February mirrors January with an average swell of 1.2m and a slightly longer period of 7.3s, meaning more power behind each wave. The swell distribution remains diverse, but the S and SSE directions (21.2% combined) deliver the most energy. Ideal wind frequency drops a bit to 44%, but the NW and WNW sectors still dominate at 12.1% and 14.5% respectively, ensuring plenty of offshore windows. The combination of solid groundswell and reliable offshore flow makes February a prime month for scoring clean, hollow waves. The lingering winter chill keeps crowds manageable, so you can often have the lineup to yourself on a good day.
