The Lowdown
Alright, Rusty here, let's talk about what's coming up.
First off, the water temp is sitting at 81°, which is about average for this time of year.
Alright, let's get real. The next few days are a bit of a write-off if you're looking for quality. We've got a solid 7ft of swell from the ENE pumping in on Monday, but it's short-period stuff at 7 seconds and the wind is a fresh cross-off breeze. It's just messy. The wave energy is moderate (629), but the conditions are marginal at best. Tuesday and Wednesday are more of the same – 7ft to 7ft, short period, and that cross-off wind keeps the surface bumpy. The energy builds through the week, getting up to a moderate 976, but it's not translating into anything worth getting excited about.
Then Thursday the 3rd of September, things get a bit heavy. The swell jumps to 10ft, but it's still short period and the wind is a strong breeze at 28 mph. The wave energy is strong (1413), but this is a messy, blown-out beast. For the average punter, it's a no-go. Friday the 4th is even bigger, with 12ft on the morning and energy hitting 1882, but again, it's raw and windy. The whole first week is a bit of a grind.
Now, let's look ahead. The standout window is shaping up around Tuesday the 8th of September. We've got a serious 15ft, 12-second groundswell from the E rolling in, and the energy is a massive 6480. The wind is a glassy offshore from the NNE, which is a game-changer. This is advanced territory, no doubt about it – too big for most, but for the crew who can handle it, Tennis Courts is going to be absolutely pumping with clean, powerful lines. The Wednesday afternoon the 9th is also a gem, with a 10ft swell from the E, a 9-second period, and the wind goes dead glassy. The energy is still strong (1555), and the forecast says excellent conditions for experienced surfers. That's the one to circle.
The second week settles down a bit. The 11th of September, Friday afternoon, looks promising with 7ft from the ENE and glassy conditions. The energy is moderate (801), and the forecast is calling for very good surf. A solid, clean option for a wider range of abilities. The 12th of September, Saturday, has 5ft waves with light cross-off winds, which will be clean and fun for a mixed crowd.
Overall, a rough start, but patience pays off. The real magic is that Tuesday the 8th and Wednesday the 9th – that's the big clean pulse for the experts. The weekend after that offers some cleaner, more manageable waves. Lock in.

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

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.
