The Lowdown
Alright, surfers, Rusty here. Let’s talk about the next couple of weeks at Otter Rock. It’s a bit of a mixed bag, to be honest. The water is a chilly 51°, which is a solid seven degrees colder than normal for this time of year, so you’re definitely gonna want the thick rubber and maybe some booties.
The opening stretch is looking pretty gutless. We’ve got surf on offer, but it’s struggling. Thursday the 20th has some chest-high WNW swell, around 5ft, with an 11-second period. The energy is moderate (688), but the cross-onshore breeze is going to put a bit of a crumble on it. It’s rideable for the keen ones, but it’s not going to win any awards. The afternoon drops off a touch. Friday the 21st drops right down to ankle-snapping 2ft, and even though the period stretches out to 14 seconds, there’s just not enough push. We’re in for a flat spell through the weekend and into the start of next week. Expect a gap of a few days here, from Friday through the middle of the following week, where you’re better off finding something else to do. The swell is tiny, the winds are messy, and it’s just a classic summer lull.
Now, there is a glimmer of hope. On the morning of Wednesday the 26th, we see some funky glassy conditions. The wind is dead, absolute glass, but the swell is still only around 2ft. It’s a hint of what could be, but not enough to get excited about. It’s a tease.
Keep your eyes on the horizon for the end of the month. Monday the 31st is still pretty average, with a lumpy 4ft in the afternoon. But then we get to Tuesday, the 1st of September. That's the standout in this whole window. Early morning on Tuesday the 1st, we’ve got a 5ft west swell with a 10-second period, and the wind is forecast to be completely glassy. The energy is solid (644), and for a point break like Otter Rock, that west swell is right in its wheelhouse. This is the one to circle on the calendar. It’s a week and a half out, so don’t book any flights yet, but the potential for some clean, head-high plus waves at a spot that can get good is definitely there. The morning session is where it’s at, as the afternoon wind is forecast to pick up and chop it out.
After that, things fade out again. The rest of the forecast is more small, choppy surf, with the wind being the main enemy. There’s nothing else that comes close to that Tuesday morning window.
Overall, the first week is pretty poor, but that Tuesday the 1st of September morning looks like the real deal – clean, glassy, and with some proper size for Otter Rock. Fingers crossed it holds. This is Rusty, signing off.

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.
