The Lowdown
Hey, Rusty here. It’s been a tough patch at Otter Rock, and the outlook is pretty bleak for quite a while.
For the first week and a half, it’s mostly flat or tiny with messy cross-onshore wind. Thursday the 13th and Friday the 14th are total losses. This pattern of small, choppy surf doesn’t let up for days.
There’s a small glimmer on Wednesday the 19th with a 3ft swell from the WNW, but it’s got short period and cross-shore wind. The energy is moderate (460), but it’s still just a marginal day compared to what we’d hope for.
The one real standout, if you can call it that, is Thursday the 20th. We see a 5ft to 5ft NW groundswell with a better 11-second period, all under a light cross-onshore breeze (10 km/h). The energy jumps to a strong 799. This is the one day that might offer some proper, rideable waves. After that, it’s back to small, weak leftovers and poor wind.
Forget the rest of the second week – it’s tiny, weak energy and cross-onshore chop. The water temp is about normal for the season.
If you’ve got one session to gamble on, make it that Thursday the 20th. Otherwise, it’s dry dock time. These flat spells are just part of the deal around here.
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.
