The Lowdown
Alright, this is Rusty, and we're taking a look at the forecast for Tennis Courts. It's a reef break that's got some potential, but it's a bit of a mixed bag over the next couple of weeks.
Overall, we're looking at a pattern where the wind is constantly blowing from the ENE, which is a cross-offshore for this spot. That keeps the surface clean, but the angle isn't perfect. The real issue is that for most of the forecast, the swell is coming from the same ENE direction, which isn't the optimum for this break. That means even when there's size, the quality just isn't there.
The best window by far is Tuesday, August 4th. We've got a solid 5ft swell rolling in from the ENE, but the key here is the period. It jumps to 11 seconds, which is a proper groundswell. That's going to bring in some real energy (combined energy of 587) and the waves will have a lot more push and shape. The wind is a gentle breeze, so it's still clean. It's not the ideal swell direction, but the extra period makes it the standout session. Expect very good surf conditions. The water temperature is about average for the time of year.
Now, the rest of the first week is a tough sell. Monday the 3rd is a no-go with 5ft of short-period, 8-second windswell and a moderate breeze – it's just messy. Wednesday the 5th and Thursday the 6th are small and weak, with poor surf conditions. By Friday the 7th, the swell drops to almost nothing, and the wind picks up to a fresh breeze.
The second week doesn't offer much hope either. From Saturday the 8th through to Tuesday the 18th, it's a long stretch of poor to marginal surf. The wind stays strong, mostly a fresh to strong breeze, and the swell is either short-period ENE windswell or a longer-period S/SSW swell that doesn't align with the break. The one slight glimmer is on Wednesday the 12th and Thursday the 13th of August, where a solid S/SSW groundswell pushes in with periods of 16-18 seconds, and the combined energy is strong (880 and 813). But the wind is still a cross-off from the ENE, and the swell direction is all wrong for Tennis Courts, so the waves will be a disorganised mess. It's a pass.
For a reef break, a long period swell like that from the south is better suited to a point or a river mouth, not here. Honestly, with the constant wind and often significant swell, the setup here looks more interesting for kite surfing than paddle surfing for most of this period.
Stay safe out there.
