The Lowdown
Alright, this is Rusty. Let’s talk about Lances Right.
We’ve got a bit of a rough start here, with a few days of grotty conditions to get through, but the second half of the outlook has some real promise brewing, especially towards early September.
Starting off, the first few days are pretty much write-offs. Saturday the 29th has onshore winds and only 5 ft swell at best, but the wind is just trashing it – it’s a pass for me. Sunday the 30th offers up a 4 ft swell, but it’s messy and onshore, plus the period is a massive 20 seconds. Long-period like that usually points to a proper groundswell, which is raw power, but with these winds? It’s not going to be the clean, lined-up stuff we want. The combined energy is up there though, hitting 1581 on Sunday afternoon (moderate energy). But it’s just not clicking with the wind.
We’re looking at a big run of marginal or poor conditions right through until the end of the first week of September. Swell sticks around between 4 ft and 8 ft, mostly from the SW and SSW, but that onshore or cross-onshore wind from the SE and SSE just kills it. By Monday the 1st and Tuesday the 2nd of September, you’ve got 8 ft of swell with moderate energy in the 3000 range, but it’s all bumpy and messy. Too big for beginners at that size anyway, and unless you’re an expert looking for a challenge in rough water, it’s not worth paddling out.
The real light at the end of the tunnel shows up on Tuesday the 8th of September. After a stretch of near-nothing, we finally see a change. Tuesday afternoon brings in a glassy, dead-calm wind – a SW wind at 3 mph with zero chop. The swell drops to a clean 3 ft from the S, but that period is a ridiculous 19 seconds. That is a very long period groundswell, meaning proper energy, smooth faces, and long lulls between sets. For an advanced reef like Lances Right, that’s the ticket. Combined energy is 748 (moderate), and the report says “expect very good surf conditions.” That’s my pick of the early run.
Then hold on. Thursday the 10th of September morning is another standout. Glassy as glass, zero wind, with a 5 ft SSW swell and a 17-second period. 1230 combined energy. That’s clean, lined up, and perfect for the advanced crew. Again, very good conditions noted.
But the true star of this entire 16-day window is Saturday the 12th of September. This is the one to circle on your calendar. We’ve got a 7 ft SSW swell with an 18-second period – that’s a serious, powerful groundswell. The wind is glassy, absolutely dead calm, from the ENE. Combined energy is 2758 on Saturday morning, climbing to 2825 in the afternoon (very strong wave energy). The report calls it “excellent surf conditions for experienced surfers,” and they’re not wrong. 7 ft at this spot with no wind? That’s a heavy, hollow wave that only the best should be paddling into. It might break a little straight at a beach, but this is a reef break – Lances Right likes that long period. Crowds are listed as “sometimes,” so expect a crew, but it won’t be a circus. If you’re advanced, that Saturday is the absolute best on offer. Sunday the 13th still looks solid at 7 ft from the SW with a 16-second period and light offshore, but the energy is even higher at 3859 – that’s very strong. Still, Saturday takes the crown.
Water temp? I’d say it’s feeling about average for the time of year, nothing to write home about.
So, to lay it out straight: the first week is mostly a washout. Tuesday the 8th afternoon and Thursday the 10th morning are little windows of glassy goodness. But the true winner, the one that gets the blood pumping, is Saturday the 12th of September.
Stay safe, check the tides, and don’t be a hero in that 7 ft glass if you’re not ready.
Rusty.

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