The Lowdown

Howdy, Rusty here with the long-range look at Otter Rock. We've got a mixed bag on the horizon, but there are a few moments where it'll come together real nice.

The first read on the forecast shows we’ve got a bit of a slow patch to start. The water temp is sitting at 57°, which is about average for this time of year, so no surprises in the wetsuit department.

Let’s get into it. The first meaningful surf of the period hits on Friday morning, September 11th. The overnight winds are set to glass right off, and we’ll see a clean 6ft swell rolling in from the NW with a moderate period of 9 seconds. It’s got a combined energy of (761), so there’s some decent grunt in the water. Conditions are described as glassy, which is a huge plus. This is the standout window for the first week; expect clean, lined-up waves and a solid paddle out. The afternoon will see a shift to a bit of a cross-on breeze, so get it early.

After that, the middle of the following week turns a bit more unreliable. There are scattered small swells through the 12th to the 17th of September, but the wind is fickle, switching between cross and cross-on with varying strength, and many of those sessions are described as marginal to poor. The swell drops off, turning into that small, short-period stuff we all have to fight through.

We hit a real lull around the 18th and 19th of September. On Saturday morning, the 19th, there’s a tiny, long-period groundswell sneaking in from the WSW. The swell height is only 1ft but with a very long 19-second period and glassy conditions. It means you might find a clean, slow peel on the tide, but you’ll need to be patient.

The real firecracker in this forecast is sitting out at the very end. Wednesday morning, September 23rd, is looking like a barn-burner. The wind is glass from the ENE, and we’ve got a legitimate 7ft swell from the NW (9 seconds). The combined energy is cranking at (949). That’s the kind of moderate-to-strong energy that will have Otter Rock pumping. Because it’s over 7ft, this one is for the experienced crew only.

The following day, Thursday the 24th, will still have some size at 5ft dropping off, but the wind picks up to a cross-shore breeze.

So, if you’re marking the calendar: Friday the 11th is your clean early call for the first week, and Wednesday the 23rd is the heavy-hitter for the experts. It’s a long way out, so keep an eye on it, but that one has the most potential.

Stay stoked,

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.
