Otter Rock Surf Forecast and Surf Report

Alright, let’s get into it. The next couple of weeks are looking pretty average for Otter Rock, but there’s a flicker of something more interesting further down the line if you’re patient. The water’s sitting at 56.7°, which is a bit colder than normal for this time of year, so don’t forget the hood if you’re heading out.

For the first stretch, honestly, it’s pretty grim. Monday afternoon the swell is only 3.6ft from the NW with a short 8-second period, and the wind is cross-onshore. It’s going to be a bit of a messy, choppy affair. Not worth getting excited about. Tuesday and Wednesday don’t get much better—still small, short-period NW swell, with cross-shore winds keeping things lumpy. There’s a tiny window Wednesday morning where the wind eases to a light cross-shore, and the swell bumps up slightly to 4.3ft, but it’s still pretty marginal. You’d be scratching for something clean.

The gap from the 16th through the 21st is mostly poor. The swell stays small and inconsistent, dominated by a weak, long-period WSW groundswell at 17-18 seconds, but the heights are pathetic. It’s not really surfable—definitely not worth paddling out for anything more than a float. Thursday and Friday the 17th and 18th have a bit more size—5.2ft and 4.3ft from the NW—but the winds are always cross or cross-on, keeping it bumpy. Still, light winds on Thursday morning might offer the least worst session, but it’s not a standout.

Now, here’s where things start to get interesting. From the 22nd into the 23rd, we see a decent jump in energy. The combined energy reading jumps up to 604-614, which is moderate, and the swell swings around to the WNW with a more workable 10-second period. Heights are still in the 4.3ft to 4.6ft range. Morning windows on the 22nd and 23rd look better with lighter winds, but the afternoon chop from the moderate NNW cross-shore blows it out. It’s still marginal for Otter Rock.

The real kicker comes at the end of the run. The 28th of September starts showing something bigger. That Monday afternoon, we’ve got a 6.2ft SSW swell—coming from the south-west, which is off-optimum for this exposed point—but the wind is a light cross-offshore, and the energy reading jumps to 972. That’s a big jump in energy and the cleanest conditions we’ve seen all forecast. It’s still a bit of a long-period swell at 10 seconds, so it won’t be breaking too crazy, but it’s the best of the run. Tuesday the 29th brings even more size—6.6ft to 6.9ft from the W and WNW—with moderate energy readings in the 1000s. The morning is still a bit cross-onshore, but Tuesday afternoon the wind swings light cross-on from the WNW, and it’s got some push. This is the standout window. The waves will have some power, and with the light winds, it’ll be cleaner than anything we’ve had. It’s still a bit big for beginners—over 5ft—but for anyone with a bit of experience, this is where you want to be. Longer period groundswell at 10-11 seconds, so there’ll be longer gaps between sets, but the shape should be a lot better than the short-period junk we’ve been dealing with.

For the real highlight, I’m looking at that Tuesday the 29th afternoon. Swell from the WNW at 6.9ft, light cross-on wind, and the combined energy just over 1077—that’s solid, moderate-to-strong energy. Otter Rock is a point break, so this longer-period swell will wrap in nicely. Not the biggest, not the cleanest, but the best on offer across the whole forecast. It’s a promising outlook, but it’s still a week and a half out, so don't book the day off work just yet.

There's nothing here that's going to be epic, and the first week is definitely a write-off for any serious surfing. But that late September pulse is something to keep an eye on. If the winds hold, that'll be the time to get wet.

Alright, stay stoked.
