Brookings seasonal overview
Best Surf Season (October - March)
The North Pacific roars to life during the fall and winter months, with average swell heights climbing above 2.3m and wave periods stretching into the 11-13 second range. While the dominant swell direction tends to be from the W to NW – not always in the optimal S to WSW window – the sheer power and long period of these swells allow them to wrap effectively into Brookings' SW-facing beach. Offshore winds from the N to NE quadrant occur frequently enough (42-55% ideal wind) to clean up the lines, especially during high-pressure setups that often settle in after frontal passages. This is the prime time for serious surf, with December and January delivering the largest, most consistent energy of the year. Storms in the Gulf of Alaska and along the polar front generate pulses of groundswell that can easily reach the 3m mark, offering classic Oregon coast power.
Fair Surf Season (April - June)
As winter's fury subsides, the ocean transitions to a more moderate state. Average swell heights drop to 2.0-2.3m and periods decrease to 10-12 seconds, but the proportion of swell from the optimal S to WSW direction increases notably (reaching over 11% in May). This shift, combined with a solid percentage of offshore N/NE winds (43-47% ideal), results in a higher frequency of clean, well-shaped waves, albeit smaller in size. Spring is a shoulder season where you can often find fun, rippable surf without the winter crowds or the extreme conditions. The Aleutian Low weakens, but late-season storms still provide occasional pulses of quality swell.
Low Surf Season (July - September)
Summer brings a pronounced lull in North Pacific storm activity. Average swell heights hover around 1.8-1.9m with short periods of 9-10 seconds, and the wave energy is overwhelmingly dominated by NW to NNW swell (often combined for >40% of the spectrum). Although the wind is at its most cooperative – ideal offshore conditions are present 54-56% of the time, thanks to a persistent thermal low that draws in northerly breezes – the lack of size and period means waves are typically small, weak, and gutless. Only the occasional remnant hurricane swell or a distant storm from the Southern Hemisphere can inject some quality, but these events are rare and short-lived. It's a time for groveling boards and summer beach vibes.

September: Hints of Renewal
September signals the start of the fall transition. Average swell height edges up to 1.9m and period increases to 10.5s – a significant jump from summer. The swell direction remains predominantly NW (26.3%) and WNW (24%), but there is a slight increase in WSW (4.8%) and SW (1.1%). Optimal directions total just over 6%, still low but improving. Winds are excellent: ideal wind 54%, with N (20.3%) and NNW (18.8%) leading, while onshore S and SSE only account for about 9.2%. Early season storms in the North Pacific begin to send pulses of longer-period groundswell, and the combination of clean offshore flow and building swell can produce some surprisingly good sessions. September offers a taste of the coming winter power, with smaller crowds and often warm water.
