Picnic Tables seasonal overview

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.

Conditions at Picnic Tables in September

September: The Transition Begins

September marks the turning of the tide. The average swell height climbs to 0.8m and the period jumps to 9.0s—the highest average period of the year, indicating more powerful, long-period energy. Swell direction shifts back to the east quadrant, with ENE (35.6%) and E (37.5%) combining for over 73% of the swell. The 0.5-1m and 1-1.5m categories grow significantly, and there's even a modest 2.3% of waves over 1.5m, mostly from ENE and NE. This is the first month where solid, rippable surf becomes more common. Wind conditions are still challenging: ideal offshore blows only 12% of the time, and onshore easterlies (E, ENE, ESE) make up over 40% of the wind. But as autumn progresses, the frequency of cold fronts increases, bringing more westerly wind days. Hurricanes and tropical storms can also throw powerful, clean swells into the mix. September is a month of potential—keep your gear ready for those magical late-summer/early-fall swells.
