The Lowdown
Alright, Rusty here. Let’s have a look at what we’ve got for the next couple of weeks over at Rock Wave.
The forecast starts off pretty rough, honestly. We’ve got a stretch from the 10th through the 21st where the scores are a slog. The first few days of the 10th and 11th have some swell pushing in – up to 7 ft from the S and SE, with long periods hitting 13 seconds on Tuesday arvo, giving it a solid energy reading (1686). But the wind is all wrong: cross-shore and cross-onshore, sometimes fresh and lumpy. The water temp is a raw 63°F – that’s 5°F colder than usual for this time of year. Combined with the rain and wind, most of the time the setup is messy. There’s a big gap here for good surf; we’re looking at a solid 11-day stretch of poor to marginal conditions, not worth paddling out for.
Now, the light at the end of the tunnel – the real standout – hits on Saturday the 22nd. The morning kicks off with a clean 5 ft swell rolling in from the SSE, period around 9 seconds, moderate energy (693). The wind turns cross-offshore from the NNE with a gentle breeze – so you can bet it’ll be clean. Wave comment calls it “expect very good surf conditions.” That is your window. Then Saturday arvo takes it even better: glassy, flat calm, 5 ft from the ESE, still 9 seconds, clean as a whistle (676 energy). This is the one to circle on the calendar.
Sunday the 23rd is a write-off again – strong breeze from the WSW at 25 mph hits in the morning, then rain and lumpy chop in the afternoon, so that session is gone. The rest of the second week fades into marginal or poor conditions again, with small swell and onshore winds picking up through the 24th and 25th. Nothing to chase.
So, the highlight is absolutely Saturday the 22nd. In the morning, with that offshore cross wind and clean lines, it’s the call. The afternoon is glass – but glass can be a bit sleepy. If you’re an intermediate surfer, the morning will give you the best of it. Just watch the break: it’s a reef, fairly consistent, and the swell direction (SSE) matches up with the optimum (S), so the shape should hold nicely. Because the break is exposed, that SSE swell will wrap in with some power.
Overall, a lot of waiting, but one solid gem if you time it right.
Take it easy,
Rusty

Information about the Rock Wave Surf forecast
The above surf forecast table for Rock Wave provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Rock Wave can be found by selecting the local surf guide option on the grey menu. Our Rock Wave 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 (Rock Wave) 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 Rock Wave 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.
