The Lowdown
Alright folks, Rusty here. Let’s talk about what’s on offer for the next couple of weeks. It’s a bit of a slow start, but there’s a real gem hiding in the second week for those who can wait.
First up, the water is sitting at 56°, which is a bit colder than normal for this time of year, so don’t forget the booties if you’re heading out.
We’ve got a long stretch of nothing too inspiring kicking off the forecast. The first real surf worth mentioning is on Saturday, 5th September afternoon. Otter Rock is seeing a 3ft of southwest groundswell, with a solid 16-second period. The combined energy is moderate at 580, but the wind is a cross-on from the northwest at 6 mph, which is just enough to mess with the surface. It’s a marginal call, and the crowds can be an issue here, so it’s not a standout.
Sunday, 6th September, is even smaller, with 2ft swell and similar long-period energy, but the wind goes cross-shore and then onshore. These are just days to keep an eye on the tide charts, nothing more.
The pattern continues through the week with small, inconsistent swell and mostly cross or cross-on winds. Monday morning, 7th September, gives us a brief moment of glassy conditions with 2ft swell, but it’s just too small to get excited about. The energy is weak at 284.
Then, we hit a dry spell. From Tuesday, 8th September, through to Friday, 11th September, the surf is a mix of weak, short-period windswell and poor conditions. The wind gets up, the waves get choppy, and it’s just not worth paddling out. There’s a gap of several days here with no real recommendations.
Now, hold onto your boards, because Saturday morning, 12th September, is the one. This is the standout. Otter Rock turns on with a 6ft swell from the northwest, period of 9 seconds. The combined energy is strong at 789. But the real magic is the wind: it’s glassy. Dead calm. That’s going to make for some clean, punchy waves. The swell is a bit too big for beginners at 6ft, so it’s more for the intermediate to expert crew. The northwest direction is a solid match for the spot’s optimum westerly swell. Get on it early, because the crowds will be around.
After that, things drop off again. Sunday morning, 13th September, sees a 2ft southwest groundswell but the wind is cross-shore, and it’s inconsistent. The rest of the second week is a bit of a write-off: small waves, poor winds, and a lot of cross-onshore chop. There’s a little window on Monday morning, 14th September, with glassy conditions and 3ft swell, but it’s weak and the period is short. It’s a marginal call at best.
The very end of the forecast, from 18th September onwards, shows some very long-period groundswell (20+ seconds) but only 1ft to 2ft. That’s not enough to push through the tide, and the winds are messy. It’s only interesting for the dedicated longboarder who’s just happy to be out.
So, to sum it up: the next couple of weeks are mostly a waiting game. The clear winner is Saturday, 12th September morning at Otter Rock. Glassy, 6ft of northwest swell, and plenty of energy. That’s your best bet.
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.
