The Lowdown
Right, grab a coffee, let’s have a look at what’s happening at Otter Rock. It’s a bit of a rough start, to be honest. The swell’s coming in from the northwest, but it’s short-period windswell, mostly between 3ft and 4ft, and the wind is stuck in a cross-onshore pattern, making a mess of things. The combined energy is weak to moderate, barely breaking 200 to 300 (269, 264, 192) for the first few days. That’s not surf, that’s just messy chop. The water is sitting at 54°, which is a massive 5° colder than normal for this time of year – that’s a serious bite for an August dip. We’re looking at a long, frustrating gap here.
Thursday the 6th through to Saturday the 15th is basically a write-off. Every session is rated poor, with that same cross-onshore wind ruining any chance of a clean face. The swell stays under 5ft, but with periods of 5 to 8 seconds, it’s just weak, short-period junk. There’s a tiny flicker on Saturday morning the 15th with a 4ft northwest swell and a light breeze, but the notes call it “marginal,” so I wouldn’t get my hopes up. You’re looking at nearly ten days of nothing worth paddling for.
Then, things start to get interesting. On Monday the 18th, we see a proper spike in energy, jumping to 820 and then 1340 in the afternoon, with a 6ft WNW groundswell at 14 seconds. The wind is still cross, so it’s not perfect, but the energy is there. The real standout, the one that’s worth marking on your calendar, is Wednesday the 19th. The morning session has a clean 7ft WNW swell with a 13-second period, light cross-offshore wind, and the conditions are described as “excellent for experienced surfers.” The combined energy hits 1435 – that’s a solid, powerful groundswell. The break at Otter Rock is a point, so that long-period swell will wrap in nicely. It’s going to be a proper session for anyone who knows what they’re doing. That 7ft is over the beginner mark, so it’s for the confident crew.
Thursday the 20th morning is also worth a look – glassy conditions with a 4ft WNW swell at 11 seconds, energy at 506. Clean, smooth, and far more manageable. That’s your best bet for a more relaxed paddle.
After that, it fades quickly. Friday the 21st drops back to tiny 2ft swell and a return to onshore junk. So, the play is clear: suffer through the first week and a half, then hit Wednesday the 19th morning for the power session, or Thursday the 20th morning for a glassy, fun-sized wave.

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.
