The Lowdown

G’day, Rusty here, with a look at what’s on the cards for Otter Rock over the next couple of weeks. Bit of a slow start, so let’s get into it.

The first few days are pretty ordinary. We’re looking at Monday the 31st of August, with a small 0.7m (2ft) SW swell (294 energy) and some glassy morning wind, but it’s rated marginal. The water’s sitting at 57°, which is a bit colder than usual for this time of year. Tuesday and Wednesday are a write-off—strong onshore winds and lumpy conditions, with the swell jumping up to 2.2m (7ft) on Wednesday morning but coming with a messy 7-second period and a howling 25 mph southerly. That’s not surfable. Thursday the 3rd of September sees the swell back to 2.0m (7ft) from the WNW, but it’s cross-on and choppy still. Nothing to get excited about.

Friday the 4th remains marginal, but we finally get a real standout on Saturday the 5th of September. Saturday morning is the pick of the first week—0.8m (3ft) of long-period SW groundswell (16 seconds, 599 energy) with glassy conditions and a light offshore. That’s clean, smooth, and will have some nice shape on the point. It’s small, but for the patient surfer, it’s worth a paddle. That afternoon turns messy again with a cross-on breeze, so get it early. Sunday the 6th is small and weak, and Monday the 7th is even smaller.

The second week looks more promising but comes with a caveat. Tuesday the 8th of September is still small, but by Wednesday the 9th we see a proper pulse: 2.1m (7ft) from the WNW (1567 energy) with a 13-second period and light cross-shore winds. That’s solid, powerful groundswell, but at this size it’s really for the experienced crew—too big for beginners. The long period also means it’ll be lining up nicely on the point, but expect longer waits between sets. Thursday the 10th holds at 1.8m (6ft) (1012 energy) with similar conditions, still clean.

Friday the 11th drops off, but Saturday the 12th of September is the real standout of the whole outlook. Saturday morning brings 2.3m (8ft) from the WNW (1072 energy) with light cross-offshore winds—clean conditions. This is excellent for experienced surfers, with real power and shape. That afternoon pumps up to 3.5m (12ft) (3371 energy) but the wind picks up, so it’ll get lumpy. Sunday the 13th holds 2.2m (7ft) in the morning with light cross-shore airs, still good but a step down in quality.

Monday the 14th and Tuesday the 15th taper off with dropping swell and increasing onshore wind. The gap from that Saturday peak to the end is a slow fade, but that Saturday the 12th is the one to circle on the calendar.

So, bottom line: don’t rush out this week. Wait for Saturday the 5th morning for a glassy little session, but the real gem is Saturday the 12th morning—big, clean, and powerful for those who know what they’re doing. Otter Rock is fairly consistent, so even if the first few days are flat, it won’t stay that way. The crowd can be around, so get in early.

Stay wet,
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.
