The Lowdown
Alright, Rusty here. Let’s chew through the outlook for Tennis Courts. This is a solid reef break that needs a good swell and clean wind to fire. The next 16 days are a bit of a rollercoaster.
The first few days are a grind. Friday the 31st of July kicks off with a 8ft swell from the east, but it’s getting hammered by a 25 mph cross-off wind. The wave energy is a massive 1411, but that wind is a problem. It’s too big for beginners and a real handful. The water temperature is 80°, which is about average for the time of year.
Saturday the 1st of August is even bigger, with a 10ft east swell and a 28 mph cross-off. The energy is still at 1408. Sunday the 2nd backs down to 8ft, but the wind is still a strong 22 mph. The energy is 1122. This whole stretch from Friday through Sunday is only for the hardcore. The wind is just too strong for a clean ride.
Monday the 3rd of August is a step in the right direction. The swell drops to 6ft, and the wind drops to a moderate 12 mph. The energy is a more manageable 553. It’s still cross-off, but it’s workable. Tuesday the 4th is the real standout of the first week. The swell is 5ft from the ENE, but the period jumps to 11 seconds, which is a proper groundswell. The wind is a light 6 mph, and the energy is 576. That’s going to be clean and glassy. The longer period will make the waves fat and walled up, which is perfect for a reef. This is your best window.
Wednesday the 5th stays clean with a light wind and 4ft swell, but it’s smaller. The energy drops to 335. From Thursday the 6th onwards, the wind picks up into the 15-19 mph range, and the swell gets short and choppy with 7-8 second periods. The energy drops, and the conditions are poor. That stretch from Thursday the 6th through to Sunday the 9th is a skip.
For the second week, there’s a small glimmer. On Monday the 10th of August, the swell direction swings to the SSW with a very long 16-second period, but the swell height is only 3ft. The wind is a cross-shore at 9 mph, with the energy at 477. It’s tiny, but the direction is correct. The best chance in the second week is Tuesday the 11th of August, with a 6ft ENE swell and an 8-second period, but the wind is a stiff 19 mph cross-off, which kills it. The energy is 628. From Wednesday the 12th onward, it’s a mix of small, short-period stuff and the occasional longer period SSW swell that’s too small to matter. The energy drops to a paltry 51 by the 15th of August. It’s a flat finish.
The standout session is Tuesday the 4th of August. The 5ft groundswell with the light wind will be the cleanest and most fun window of the entire forecast. For the second week, Tuesday the 11th is the only one with any size, but don’t expect much.
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.

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.
