The Lowdown
Alright crew, Rusty here. Let’s break down what’s happenin’ at Otter Rock for the next couple weeks.
The first ten days or so are a total bust. From Friday the 21st right through the end of August, the surf is flat and messy. Small swell, junk wind, and the wave energy is weak (between 184 and 415 units). You’ll see a few 2ft to 3ft lines, but they’re blown out or just have no push. Sunday the 23rd has a brief moment of glassy conditions with a 3ft WNW swell, but it doesn’t last and the energy is low (184 units). Don’t bother.
Things start to get interesting as we hit September. Monday the 1st of September brings a big pulse of energy – 7ft to 8ft of WNW groundswell with a 11 to 12-second period, and the combined energy jumps to 1325-1796 units. That’s serious, but the wind is onshore and conditions are rough. Only for the experts, and even then it’s a gamble.
The standout session, the one you’ve been waitin’ for, is Wednesday the 2nd of September morning. Glassy conditions, a clean 8ft WNW swell at 12 seconds, and energy cranked up to 1774 units. This is excellent surf for experienced surfers – long period groundswell, clean faces, and the point should be firing. The afternoon gets a bit cross-on, so get in early.
Thursday the 3rd of September morning is another good one, with 7ft of NW swell at 11 seconds, glassy conditions, and energy still solid at 1059 units. Another prime session for the experienced crew.
For beginners, sorry, there’s nothing in the first week of September that’s safe. The swell is way over 5ft, and once it hits 8ft, that’s expert-only territory. Stay on the beach and watch the show.
The wind on the standout days is a major win – glassy or light offshore, so the waves will be clean and lined up. Just remember, long-period swells like this (12 seconds) can be a bit finicky at beach breaks, but Otter Rock is a point, so it’ll handle it well. Expect crowds, it’s gonna be popular.
Bottom line: the first ten days are dead. The action starts September 1st, but the best of the best is Wednesday the 2nd of September morning. If you’re good enough, you’ll have a session to remember.
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.
