The Lowdown
Alright folks, Rusty here. Let's have a look at what Otter Rock has in store for us over the next couple of weeks. Gotta be honest with you, it's a bit of a slow burner, but there's a glimmer of something decent if you're patient.
Right now and for the first week or so, we're looking at a persistent run of small, weak surf. The combined swell energy is mostly in the low to moderate range (around 240 to 430), with waves hanging between 1ft and 3ft. The direction is a steady SW to WSW, which isn’t bad, but it’s coming in with a cross-onshore wind that’s keeping things choppy. The water temp is about average for the time of year. Honestly, it’s poor to marginal out there – not worth wetting a wetsuit for unless you're desperate for a paddle.
There's a bit of a change coming through on the 1st and 2nd of September. The swell ticks up to around 4ft from the WNW, but the period drops to a short 9 seconds. That’s windswell, not groundswell. It’ll be weak and crumbly, and with the wind still in that cross-onshore pocket, the quality just isn't there for a proper session. The combined energy stays moderate (around 360 to 390), so nothing’s firing.
Now, keep an eye on Thursday, the 3rd of September. That morning, we see the swell jump to 5ft from the WNW, with combined energy hitting 553. It’s the first time we get a score of 2, and with a gentle cross-shore breeze, it might clean up a bit. The period is still a short 10 seconds though, so it’ll be a bit crumbly and stormy. It's not a stand-out, but it’s the best of a pretty average first week.
But here’s where it gets interesting. The real highlight is shaping up for Sunday, the 6th of September. The morning session is looking like the one to circle on your calendar. We’ve got a 4ft NW groundswell, a solid 10-second period, and glassy conditions. The combined swell energy is a solid 535. That combination is proper. The wind is glass, so Otter Rock (a point break) will be clean and have some nice shape. It’s not huge, so it’s good for a wide range of surfers, but it won't be too big for beginners. The water’s still about average for the time of year. The crowds are "often" here, so expect some company, but when the conditions line up like this, it's worth it. The swell direction from the NW matches the optimum for this spot perfectly. That Sunday morning is the standout, no question.
After that, the next couple of days on the 7th and 8th hold a bit of size, with the swell pushing 5ft to 6ft on the 8th, but the period stays short and the wind goes cross-onshore again, chopping it up. Those are better left for the experts if it gets too lumpy. The 6ft might be a bit much for a beginner anyway.
So, in short: the first week is a write-off. Don't bother. Wait for that Sunday, the 6th of September, set your alarm for first light, and get ready for a glassy, fun session at Otter Rock. It’s the only real standout in the whole 16-day window.
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.
