The Lowdown

Alright folks, Rusty here. Let's be straight with you – the next couple weeks at Otter Rock are looking pretty grim. We've got a long stretch of poor conditions ahead, with mostly cross or cross-onshore winds and mixed-up, weak surf. Don't get your hopes up.

Thursday the 20th morning is about as good as it gets to kick things off, but that's not saying much. We've got a clean, clear sky, a light breeze, and a 5ft swell rolling in from the WNW with an 11-second period. The combined energy is moderate (688). Honestly, it's pretty marginal; the wind is cross-onshore, so it's not going to be glassy perfection. It's a "maybe" session for the die-hards.

From there, it's a real bummer. We go right into a solid week-plus of poor surf quality from Friday the 21st all the way through the end of August. The swell drops right off, and the wind stays messy. Occasionally you'll see a longer period swell, like the 14-second SW groundswell on the 21st, but with the wind on it and barely any size (2ft), it's a non-starter. The water temp is about average for the time of year, nothing unusual to report.

Then we hit September, and things start to get interesting, but it's a long-range promise. On Tuesday the 1st of September, we finally see a pulse of energy. The afternoon brings a 7ft swell from the WSW with an 11-second period. The combined energy jumps to a strong 958. Winds go glassy, swinging from the WSW at only 3 mph. It's looking like it will be clean. This 1st of September window is the standout of the entire forecast, but it's far out, so treat it as a promising rumour for now. It's not too big, but at 7ft, it's getting into expert territory if the swell focuses.

The next morning on Wednesday the 2nd still has some push with a 4ft W swell at 11 seconds (727 energy), but the cross-onshore wind is back, messing it up. Thursday the 3rd is more of the same, just marginal.

So, to wrap it up: The first week is a write-off. The best bet on offer, and the only real standout, is the afternoon of Tuesday the 1st of September. Mark it in your calendar, but be patient. This run of poor surf is pretty normal for the area in late summer, so don't sweat it too much. Things can change.

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.
