The Lowdown
Alright, folks, Rusty here. Let’s have a look at what Otter Rock has in store for us.
Right now, it’s a pretty quiet start. We’ve got tiny, short-period swell rolling in, but the wind is a real problem. It’s mostly cross or cross-onshore, and that's just trashing the surface. For the first week or so, it's a tough watch. We’re looking at weak wave energy, with values struggling to even reach 400 (combined swell energy around 179-397). The water temp is about average for this time of year.
The first few days are basically write-offs. Monday the 10th and Tuesday the 11th are poor, with tiny waves and shitty wind. Wednesday the 12th picks up a bit of size in the afternoon, with a 5ft swell from the WNW, but the period is only 7 seconds and it's still cross-onshore. That's messy closeout material. That cross-onshore wind sticks with us right through the first weekend, making everything choppy and frustrating. The surf improves a little on Friday the 14th and Saturday the 15th, but it's still more of a "maybe paddle out if you're desperate" situation than something to get excited about.
Now, the real standout is shaping up for Monday the 19th of August. That Wednesday morning is looking like the best we’re going to get in this whole stretch. We’ve got a clean 5ft swell pushing in from the WNW with an 11-second period. That’s solid groundswell energy – the combined energy is a strong 649. But the real hero is the wind: it’s going glassy. That is a massive positive. For a point break like Otter Rock, this could be damn good. The swell is a bit over 5ft, so it’s not for the groms, but for anyone who can handle it, the morning of the 19th should offer some of the cleanest, most lined-up waves we’ve seen. Get on it if you can.
Beyond that, the second week looks more inconsistent and less reliable. The swell hangs around, but the wind turns cross-onshore again, so the quality drops off quickly. There will be waves to be had if you're keen, but nothing that hits the same high as that glassy morning on the 19th.
Rusty.

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.
