The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for the next couple of weeks.
Honestly, it's a tough run. For the first week and a half, we're staring down a lot of "poor surf conditions" and "marginal" calls. There's a real gap here with hardly anything worth paddling out for. The first real glimmer of something doesn't show up until Wednesday morning, the 19th of August, but even then it's only marginal.
The standout, if you can call it that, is on Thursday morning, the 20th of August. We've got a 5 ft swell rolling in from the WNW with a period of 11 seconds, giving a combined energy of 723 (moderate). The wind is light and cross-onshore from the NW, so it'll be a bit bumpy but still the best we'll see. At that size, it's a beginner-friendly wave, but the cross-on wind won't make it perfect. This is at Otter Rock, a point break that's exposed to the swell and works best with a W direction, so that WNW swell is in the right ballpark.
After that, the rest of the run is a real mixed bag of weak, short-period swells and choppy wind. The energy drops off fast, and by the time we get to the end of August and into the 1st of September, we're looking at small, weak swells with combined energy struggling to get out of the 200s. The water temperature is about average for this time of year, so no surprises there.
For the second week, don't hold your breath. The 27th of August Thursday afternoon sees a 5 ft swell from the WNW, but it's a short 9-second period and the wind is straight cross-shore, making it messy. The 28th of August Friday has a similar 6 ft swell from the NW, but again, short period and onshore winds ruin it. It's a bit of a kite-surfing setup on those days rather than a clean paddle session.
Bottom line: this 16-day window is a tough one. The surf is poor to marginal at best, and there's a long stretch of days with nothing. The 20th of August Thursday morning is your best bet, but don't expect a classic. Forecasts can change, so keep an eye on it, but as it stands, it's a lean run.
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.
