The Lowdown
Alright, I’ve had a look at the charts and all I can say is… it’s slim pickings out there at Otter Rock (Oregon). I mean, geez, when the whole 16-day window is pretty much a string of “poor surf conditions” you know it’s a tough one. The good news? The swell direction is hitting that W-WNW sweet spot for the point, but the wind just won’t cooperate. We’ve got a gap of no real surf on offer right now, and honestly, the first whisper of anything half-decent doesn’t show up until Thursday the 20th of August.
Alright, let’s talk about that Thursday morning on the 20th. The swell picks up a touch to 5ft from the NW, with a period of 11 seconds giving it a bit of grunt – combined energy is moderate (830). Now, the reading says it’s marginal, which I’m taking as a “maybe if you’re desperate” call. The wind is light and cross-onshore from the NW at 6 mph, so there’ll be some ripples on the face, but it won’t be a total washing machine. For a beginner spot, 5ft is getting a bit full-on, but it’s not insane. The point should handle it okay, just don’t expect perfection. It’s about the best we’re gonna see for a while.
Friday the 21st afternoon has a brief moment where the wind swings onshore from the WSW at 6 mph, but the swell drops right back to 2ft from the SW with a 14-second period. That’s a long period for such a small wave, meaning the energy is there (321) but it’s just not wrapping in with any power. Honestly, feels like a washout.
Looking further out, things just stay messy. Lots of cross-shore wind from the NNW, lots of lumpy chop. Every once in a while, like on the 31st of August, the combined energy pushes into the 500s (504) but the waves are only 3ft and the wind is cross, making for a jumbled, frustrating session. There’s a morning on the 1st of September with a light cross-onshore from the NNW and a long period 2ft swell from the WNW, but it’s marginal at best.
Bottom line, Otter Rock is a point break that needs clean conditions to really shine, and we just aren’t getting them. The water is running way colder than normal for this time of year, which doesn't help the vibe. If you’re a beginner, sit this one out. If you’re determined, that Thursday the 20th morning is your best shot, but keep your expectations low. A break that’s fairly consistent is having a real off spell. Forecasts can change, but right now, it’s a struggle.

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.

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.
