The Lowdown
Alright crew, Rusty here. Let's break down Otter Rock over the next couple weeks. It’s a slow start, but hang tight.
The pattern is pretty average early on. Plenty of waves, but the wind’s mostly cross or cross-onshore, keeping things bumpy. Water temp is about 56°F, right where you’d expect for this time of year.
Starting Friday the 11th, we’ve got a 5ft NW swell, but the cross-onshore wind kills it. Energy’s moderate (812). Saturday the 12th drops to a 3ft SW swell, still windy. Sunday the 13th through Monday the 14th is more of the same—small, choppy, nothing special.
The first real chance comes Saturday the 19th at dawn. Glassy conditions, 4ft NW swell (398 energy), wind is dead calm. That’s a clean little session if you’re keen. Sunday the 20th drops to 2ft, but check the period—18 seconds. That’s long-period groundswell (363 energy). Small, but those long lines could work well on the point.
The absolute standout is Wednesday the 23rd morning. Glassy again, 2ft SW swell with a 16-second period, and the combined energy jumps to 607. Clean, glassy, and that long-period SW swell should wrap in perfectly. Best of the whole run, no question.
The rest of the third week stays small and bumpy until Saturday the 26th. That morning brings a big jump—6ft from the WNW with a very long 16-second period and massive 1885 energy. That’s serious power. But it’s cross-shore wind, so not perfect. 6ft is getting big for beginners. The afternoon hits 7ft with 2085 energy—expert only, and still cross-shore chop.
So here’s the call: Saturday the 19th morning is a small clean option. But the one to lock in is Wednesday the 23rd morning—glassy, clean, long-period groundswell. That’s the pick.
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.
