The Lowdown
Alright folks, Rusty here, looking at the charts for Otter Rock. Honestly, it’s gonna be a long, frustrating wait for any decent surf. The next week or so is a write-off for anything worth paddling out for.
The water is absolutely freezing too, a very unusual 52°, a massive 8° colder than it should be for this time of year. You’ll want a thick hood and booties for sure if you’re gonna tough it out.
Right now, August 21st through the end of the month, it’s just small, weak, and messy. We’re seeing tiny 2ft to 2ft scraps with most of the energy from short-period windswell, and almost every session is plagued by cross-onshore wind. The combined energy is weak, all below 400. It’s a long stretch of marginal or poor surf, a real flat spell for the area.
The first glimmer of something better shows up on Sunday, August 31st into Monday, September 1st. I’m watching the morning of September 1st. The swell jumps to 7ft from the NW with an 11-second period. That’s a big bump in energy, the combined reading is a beefy 1177 – solid, moderate to strong energy. That’s a little too much heft for beginners, as it’s over 5ft, but a classic groundswell pulse for the more experienced crew. The wind is light from the NNW, so it’s not quite clean offshore but still manageable. The biggest problem is the wind turns cross-shore and picks up by the afternoon, chopping it all up. So, that morning session on September 1st is the standout, your best chance at some real power.
After that, the swell hangs around 4ft to 7ft into the first week of September, but the wind stays mostly cross-shore or cross-onshore from the NNW, keeping conditions pretty bumpy and poor. There is a chance on the morning of September 4th with that 7ft NW swell and lighter winds from NNW that might offer a slightly cleaner window for experts.
Bottom line: It’s a tough run. The one highlight to circle is the morning of September 1st. Don’t get your hopes up for anything else.
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.
