Picnic Tables - surf spot statistics

Best Surf Season (October - March)

As the North Atlantic cranks up its winter engine, Picnic Tables comes alive from October through March. This is when the average swell height hovers around 0.9m to 1.0m and wave periods lean into the 8-9 second range, offering punchy, rideable surf. The dominant swell directions shift into the optimal NE-ESE window, with ENE and E pulses making up over 40% of the energy. Strong extratropical lows spinning off the coast of Greenland and the Canadian Maritimes send long-period groundswell our way, often arriving just as cold fronts swing through. These fronts bring offshore winds from the SW-WNW quadrant, creating clean conditions for up to 15% of the time. Sure, the wind can be fickle, but when a low pressure system aligns with a high pressure ridge building from the west, we see that magic combo: solid, clean lines peeling down the beach. November stands out as the peak, with the highest average swell height of 1.0m and a decent shot at offshore flows.

Fair Surf Season (April & September)

April and September serve as transitional months, offering a mix of fading winter energy and building summer patterns. Average swell height sits at 0.8m with periods around 8-9 seconds. The swell direction is still dominated by the east quadrant (E and ENE), but the frequency of strong storms drops off. Wind patterns become more variable: in April, the percentage of ideal offshore wind dips to 12%, while September sees 12% as well. You'll still score fun, rippable waves on the better days, especially when a late-season nor'easter or early autumn tropical system brushes the coast. But overall, consistency takes a backseat to winter's fury. These months require a bit more patience and a keen eye on the forecast.

Low Surf Season (May - August)

From May through August, Picnic Tables falls into a summer slumber. Average swell height plummets to 0.5-0.7m, and periods drop below 8 seconds, resulting in small, groveling conditions. The dominant swell direction becomes almost entirely from the east (E and ESE), often generated by local sea breezes or distant tropical waves that lack power. The real killer is the wind: onshore flows from the NE-ESE quadrant dominate as the subtropical high pressure sets up shop offshore. Ideal offshore wind from the west blows only 7-10% of the time. Most days you'll find choppy, messy surf under 0.5m. That said, if you time it right with a passing tropical storm or a rare westerly wind event, you might snag a few fun waist-high waves. For the most part, this is the low season—bring a longboard or explore other spots.

August: Slight Uptick, Still Soggy

August shows a whisper of improvement. The average swell height inches up to 0.6m with an 8.1s period. Swell direction remains dominated by E (44.9%) and ESE (27.6%), but there's a slight increase in 0.5-1m waves (about 35% of total) and a small percentage of 1-1.5m waves (1.2%). Still, the vast majority is under 0.5m. Wind conditions improve a little: ideal offshore wind rises to 9% of the time, with the SW-WNW quadrant showing slightly more frequency (SW 7.7%, W 3.3%, WNW 2.2%). Onshore easterlies still dominate (E 10.8%, ESE 13.8%, SE 11.5%), so choppy conditions prevail. August is the last month of the low season, but the increased activity of Atlantic hurricane season occasionally spins up a decent swell. If a hurricane tracks well east and stalls, we can see longer-period E swell with cleaner winds from the west. Those are the sessions that redeem the summer—keep an eye on the tropics.
