The Lowdown

Alright folks, Rusty here. Let's have a look at the next couple of weeks for Otter Rock.

The window opens with a bit of a struggle, to be honest. The first few days are pretty ordinary, with onshore and cross-shore winds mucking up what little swell is around. It's not until September 4th that things start to shape up.

Early on the 4th, Friday morning, we finally get a clean window. There’s a 6.6ft WNW swell pushing through with a light ESE cross-offshore breeze. That’s going to put some proper lines into the point and it should be a fun one for the experienced crew. The energy is reading at 1018, which is a decent, moderate push of water. We finally get a wave worth getting out of bed for.

The 5th holds some promise too. Saturday morning drops to a smaller 2.3ft, but it’s clean as a whistle with a glassy surface and that southwest swell has some serious legs on it. A 16-second period groundswell tells you there’s plenty of push behind those waves, and it’ll be reeling down the point. The energy is a bit weaker at 520 but the quality will be high. Don’t expect big barrels, but for a longboard or a fish, it'll be a treat.

There's a bit of a lull midweek, with things getting small and the wind turning onshore again for a few days. But then the following Thursday, the 10th, looks very interesting. The morning has another glassy period with a 5.9ft WNW swell and 10-second period. Combined energy of 974 means it’s got some meat on it. That could be one of the best mornings of the run.

Further out, around the 12th and 13th, the swell kicks back up into that 6.6ft to 6.9ft range with a longer period, but the wind is looking cross-shore and it might get a bit messy. Keep an eye on the 14th as well – there’s a drop in period to 7-8 seconds which can make for some softer, less organized waves, but the wind is supposed to be glassy, so it could be fun if you manage your expectations.

So, the standout windows are the mornings of the 4th and the 10th. The 5th is the pick if you’re after something cleaner and a bit more mellow. Overall, the water is running a bit colder than normal for this time of year, so maybe grab the hood if you're sensitive.

For the second week, we’ve got some more swell around the 12th and 13th but the wind looks iffy. It's promising, but expect to pick your moments. The 14th could be a surprise with glassy conditions despite the shorter period.

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.
