The Lowdown
Righto, the crew’s lookin’ at a pretty flat and messy stretch ahead for Otter Rock (Oregon). Honestly, if you’re itchin’ to paddle out, you’re gonna have to be patient, and you might need to keep your expectations low. The water temperature is a chilly 53°F, which is about 5°F colder than normal for this time of year, so you’ll be wanting a good thick wetsuit.
The first solid call comes on Saturday morning, August 30th. I know that feels like a lifetime away. The build-up through the prior week is mostly cross-onshore junk with poor conditions. Around Friday morning August 28th, you’ve got a small 5ft swell from the NW, but it’s a short, weak period of 6 seconds and the wind is still messy.
Now, for the standout window. Look to the very end of the run. On Sunday, August 30th, the afternoon shows a hint of something, but the real gem is the following weekend. The best on offer is Saturday afternoon, August 29th at Otter Rock. We’re talking a tiny bit of long-period swell at 2ft from the SW with a 17 second period, and the real kicker is it’s glassy. Total wave energy is moderate at 289, but for this break it means clean, glassy conditions. Because the swell is small and the conditions are calm, it’s an absolute beginner-friendly day. The crowds at Otter Rock can be around often, so you might have company during this rare window of clean conditions. Also keep Tuesday morning, September 1st, in the back of your mind. It’s another glassy morning with a 2ft, 14-second SW swell and moderate energy at 321. The wind is glass again, so it’ll be clean, but it’s still tiny and inconsistent, which is typical for this area.
The rest of the outlook is filled with poor surf conditions, choppy water, and winds that are mostly onshore or cross-onshore. If the wind picks up like it does through those middle weeks, the setup at this beach-and-point might actually look more interesting for kite surfing than paddle surfing.
So there you have it. Not a classic run, but that late-August glass-off is a real treat if you’re keen on a peaceful session.

Information about the Otter Rock Surf forecast
The above surf forecast table for Otter Rock provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Otter Rock can be found by selecting the local surf guide option on the grey menu. Our Otter Rock surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Otter Rock) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Otter Rock may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
