The Lowdown
Alright, Rusty here. Let’s talk about what’s coming up for Tennis Courts.
Honestly, the outlook is a mixed bag. We’re starting off with a bit of a nothing-burger for the first few days. The swell is tiny and the wind is a persistent cross-off, which keeps things clean but not exactly firing. The water is sitting at 81°, which is about average for the time of year, so no complaints there.
The real interest starts to build around the middle of next week. Wednesday the 12th sees a small but serious pulse of south groundswell rolling in. The swell is only 3ft, but the period is a solid 18 seconds – that’s proper long-period energy. The combined energy is strong, hitting 864. This is a point break and reef setup, so those long lines will wrap in nicely. The wind is still cross-off, which is a bit of a drag, but it’s not howling. This is about as good as it gets in the window. Thursday the 13th morning holds similar promise with 4ft of south swell at 16 seconds, combined energy of 924. It’s not massive, but the quality of the wave will be there for the advanced crew.
After that, things get messy. From Friday the 14th right through to the 19th, the wind really cranks up, with strong breezes from the ENE pushing 25 to 28 mph. The swell jumps up, hitting 7ft to 8ft, but it’s short-period wind swell with a period of only 7 to 8 seconds. The waves are going to be lumpy, wind-blown, and pretty average. The energy is there (700-800 range), but it’s not the kind of surf you want to paddle out for. At that size and with that wind, this setup looks more interesting for kite surfing than paddle surfing.
For the standout, I’d pin it on Wednesday the 12th and Thursday the 13th. The south swell direction is a perfect match for the optimum swell direction here, and the long period means the reef will really shape those waves. It’s not a big day, but it’s a clean day with some proper push. The break is “fairly consistent” which is good, but be aware it can get crowded sometimes.
So, the first few days are a write-off, then a solid mid-week window, then a week of windy, blown-out conditions. The 20th of August looks like it might try to clean up again with a smaller south pulse, but that’s a long way out and the confidence is low.
Rusty.
