The Lowdown
G’day, Rusty here. Look, I’ve got to be straight with you – the next couple of weeks at Tennis Courts are a bit of a mixed bag, and honestly, there’s nothing that’s going to blow you away. We’ve got some swell around, but the wind and conditions keep getting in the way. Let’s walk through it.
We kick off Sunday, September 6th, with a solid 7ft ENE swell, period around 12 seconds, so there’s a bit of energy in the water (combined energy 1951). Problem is, that cross-off wind is pumping at 19 mph, which keeps it clean enough, but the forecast is calling it marginal. That’s a fair call – it’s not going to be pretty, and for an advanced reef break, you’d want it cleaner. Monday the 7th sees a bump in size, 8ft from the ENE, but the wind goes cross-shore and the energy jumps to 3601 – strong wave energy. But the conditions are described as having a cross-chop, so it’s messy. Tuesday the 8th is a write-off: onshore wind and poor surf. Don’t bother.
Wednesday the 9th drops right off – 3ft from the SSW, period 14 seconds, energy down to 526. The cross-off wind returns, so it’s clean, but it’s small and marginal. Not worth the paddle. Thursday through Saturday (10th–12th) stays small, around 4ft to 5ft from the ENE, with period dropping to 7–12 seconds. The wind stays cross-off, so it’s clean, but the scores are low – marginal at best. You might get a fun little wave if you’re desperate, but nothing to write home about.
Then we hit a big gap. Sunday 13th through to the end of the forecast, the swell drops to 1ft to 4ft, mostly from the SSW or SW. Periods get long – 15 to 22 seconds – so it’s proper groundswell, but the size is tiny. The wind stays cross-off for most of it, but the energy is weak (mostly two-digit or low three-digit values). Monday 14th afternoon has a 22-second period and 1ft swell, with light cross-off winds and a mention of “expect good surf conditions” – but let’s be real, 1ft is barely a ripple. That’s a long wait for nothing.
Overall, there’s no standout here. The best chance for a session is probably Sunday the 6th if you’re an expert and can handle the wind, or maybe Monday afternoon the 7th despite the chop. But honestly, I’d keep an eye on the forecasts – things can change. Right now, it’s a tough stretch.

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 Tennis Courts 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.
