The Lowdown
Alright mate, Rusty here. Let’s break it down.
The first week is a flat-out dud. Nothing. Then we get a few chances, but it’s never really cooking. The only spot in the game is Tennis Courts, an advanced reef break that’s pretty fickle.
Water temp is about 82°, dead average for this time of year.
The best window is the morning of Thursday, September 3rd. Swell is a clean 6ft out of the ENE, with a 8-second period, and the wind is a nice cross-off at 12 mph. The energy is moderate (736). That’s your best bet, but the short period means the waves won’t be the most powerful.
Friday, September 4th morning is another option. Swell is 6ft from the ENE, with a gentle cross-shore wind at 9 mph. Energy is a bit stronger (838), but it’ll be a little more chopped up.
After that, it’s back to marginal. A small SSW swell shows up on the 6th, but it’s onshore and weak. The 10th has a longer period swell (12 seconds) but it’s blown out by a strong breeze.
So, for the advanced crew, the 3rd of September morning is your only real shot at something clean. Not a classic, but it’s all we’ve got.
Rusty.

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. Our Tennis Courts 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 (Tennis Courts) 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 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.
