The Lowdown
Alright, Rusty here again. Let me tell you how it’s looking in feet and miles per hour. I won’t lie to you—this 16-day stretch for Otter Rock is pretty flat and frustrating. There’s a big dry spell right at the start, and the first anything even worth looking at doesn’t show until Wednesday August 19th.
The whole pattern is just small, weak swell mixed with winds that won’t clean up. Most of the combined energy readings hang around the 200 to 400 range, which is low to moderate. Water temp is 53°F, which is more than 6°F colder than normal for the time of year—so you’re gonna feel that chill.
The best of a bad situation comes Wednesday August 19th in the morning. We’re looking at swell around 3 feet from the WNW with a solid 12-second period—that’s groundswell, and for a point like Otter Rock that does well with W to WNW, the direction is fine. Combined energy hits 565, the strongest we see in the whole run. But the wind is cross-onshore from the NNW at around 15 km/h (about 9 mph), and that’s going to keep the surface bumpy. It’s not clean, but it’s the most potential we get.
Thursday August 20th afternoon is another one to watch: swell pushes up to about 5 feet from the WNW, but the period drops to 11 seconds and the cross-onshore wind is still there. Energy climbs to 638, so there’s a bit more power, but the wave face will be lumpy and hard to enjoy. These two sessions are the true heads-up for the whole 16 days.
After that, it’s mostly small, choppy, and wind-affected right through to the end of the month. There are a few pulses around 5 feet from the NW and NNW from August 22nd to 28th, but with very short periods of 6 to 8 seconds, it’s going to be weak and messy under fresh cross-shore winds. Crowds aren’t likely to be an issue because frankly, there’s not much to crowd for.
If you’re really keen, aim for Wednesday morning August 19th or Thursday afternoon August 20th. Otherwise, it’s a long wait for much better. Forecasts can always improve, but right now this is a tough outlook.
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.
