The Lowdown
G’day, Rusty here. Let’s get straight into it. The next couple of weeks are a bit of a mixed bag for Rocky Lefts, but there’s some proper size on the horizon if you’re willing to wait. We’re looking at a slow start, a messy middle, and then a solid pulse of groundswell that should get the blood pumping.
First up, the water’s sitting at 58° – that’s pretty much spot on for this time of year, so no dramas there. Wednesday morning (the 5th) kicks things off with a clean 6ft SW swell. It’s a bit of a lumpy one, but the offshore SE wind keeps it tidy. The energy is strong (1301), and it’s breaking with a bit of purpose. This is a good one to get your head wet. The afternoon drops slightly to 5ft but is still clean. This is the first real taste of the good stuff.
Thursday morning (the 6th) is a bit of a letdown – the swell drops to 3ft and goes glassy, which is nice and clean but pretty gutless. Not much push there. Then things get messy. From Thursday afternoon right through Sunday, we’ve got onshore winds and the swell gets chopped up. Friday (the 7th) is small and crumbly, not worth your time. Saturday (the 8th) sees a bit more size – 5ft to 6ft – but it’s lumpy and cross-onshore, making it a real battle. Sunday (the 9th) turns nasty: 10ft of NW windswell with strong onshore winds. That’s blown-out chaos, pure and simple. If you’re a kite surfer, this might be your window, but for paddle surfing, it’s a no-go.
We get a breather on Monday morning (the 10th) – the wind swings offshore and we get a clean 5ft WSW groundswell, but the period is short and the energy is moderate (1494). It’s surfable, but it’s not the standout. The rest of that week is pretty average – cross-shore winds, smaller swells, and a lot of chop. Nothing to get excited about.
Now, here’s where it gets interesting. The swell starts to build again around Saturday the 15th. The morning brings a clean 6ft WSW groundswell with a solid 16-second period. The energy is strong (2284) and the offshore SE wind keeps it glassy. This is a proper session. The afternoon pushes up to 8ft, still clean, but it’s getting bigger. Sunday the 16th is the big one – 12ft of WSW groundswell with a long 16-second period. This is serious, proper power. The wind is cross-offshore, so it’s still clean, but this is only for experienced surfers. The energy is through the roof (6304). The Monday after (the 17th) holds at a solid 10ft with a light offshore wind and a 14-second period. This is another excellent day for the crew who know what they’re doing.
Long-period groundswell like this can break a bit straight at beach breaks, but Rocky Lefts is a reef, and that’s where these swells really shine. The lines will be long and the power is undeniable.
After that, it settles down again. The middle of the second week sees the size drop back to 5ft to 5ft, with some cross-onshore winds on Tuesday and Wednesday (the 18th and 19th). Nothing special. But then, on Thursday the 20th, we get a final gem – a clean 5ft WSW swell with light offshore winds in the morning and flat calm, glassy conditions in the afternoon. A perfect, mellow end to the run.
So, the standouts here are Wednesday morning (the 5th) for a clean, punchy session, and the entire weekend of the 15th to the 17th for the big, powerful groundswell. The big days are for experts only – 8ft plus is serious. Keep an eye on that forecast, it’s promising but a week and a half out, so it’s not set in stone. Crowds are always a possibility at Rocky Lefts, so get in early.
Rusty.

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