The Lowdown

G’day, I’m Rusty. Let’s have a look at what’s coming up at Otter Rock.

Right off the bat, the water’s running at 51°F, which is a solid 8°F colder than normal for this time of year – that’s seriously unusual, so you’re gonna want a thick suit and boots if you’re paddling out.

The next few days are a bit of a write-off, to be honest. We’ve got a long gap of small, weak, and messy conditions. Thursday the 20th of August afternoon sees a 5 ft swell from the WNW at 11 seconds, but it’s cross-on from a light NW breeze, and the combined energy is only moderate at 621 – it’s pretty marginal. Friday the 21st drops right off, with a tiny 2 ft SW swell, and the wind stays cross-on, making it chop city. Saturday the 22nd and most of the next week are the same story: small swell, poor surf, and onshore winds. There’s really nothing worth paddling out for until Sunday the 23rd, when the morning brings a bit of hope. The swell is only 4 ft from the WNW at a short 8 seconds, but the wind goes glassy – a light NW of just 3 mph – and conditions are clean. The combined energy is moderate (252), and for a beginner-friendly spot like Otter Rock, that’s about as good as it gets in this run. It’s fairly consistent here, and with the glassy setup, it’s your best bet for a few fun waves.

After that, it’s back to small, weak, and cross-on for over a week straight. Swell stays under 2 ft, periods are mostly long (14–18 seconds) but the energy is low (136–356), and the wind never really gets clean. It’s a long stretch of nothing. The only other flicker of life comes on Thursday the 3rd of September, when a 6 ft W swell at 10 seconds rolls in, with a combined energy of 712 (moderate to strong). The morning has a light NNW cross-shore, but it’s still a cross-shore, not offshore. By Friday the 4th, the swell hits 7 ft from the W at 10 seconds, with energy up to 1324 – that’s proper strong. But the wind is cross-on with a NNW breeze, and it’s too big for beginners, solidly in the expert zone. The period is short, so it’s gonna be a bit lumpy and messy, and with the wind, it’s not the cleanest. Still, if you’re an experienced local and you don’t mind a bit of a chop, that Friday morning might offer some grunt.

Overall, it’s a lean 16 days. The Sunday morning the 23rd of August is the standout for a clean, friendly session, and the early September pulse is for the big-wave crew only. Take it as it comes.

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.
