Table - best surf conditions forecast for Tennis Courts over the next 16 days.
Alright, let’s break it down. Tennis Courts is a reef break that really wants a SSE swell, but we’re not getting that for a while. The first stretch, starting Monday 13 July, is a total washout. The swell is coming from the wrong direction, the wind is cross-off, and the conditions are just poor or marginal. You’re looking at a solid week with nothing to ride.
The energy starts to pick up around the 23rd, with swell heights getting up to 6 to 6 feet, and combined energy in the 700s to 800s (moderate to strong energy). The wind is still cross-off, but it’s clean. The period is short (7-8 seconds), so the waves will be a bit jumbled, but it’s a start.
The real standout window is from Saturday 25 July to Tuesday 28 July. On the 25th, you’ve got 6 feet of ENE swell with a period of 8 seconds, and combined energy of 845 (strong energy). It’s a bit much for the groms, but for the advanced crew, it’s on. The wind is a moderate cross-off, so the surface is clean. Crowds are ‘sometimes’ here, so you might have company, but not a circus.
The pick of the week might be Sunday 26 July, morning. You’ve got 6 feet of ENE swell, combined energy of 929 (strong energy), and the wind drops to a gentle breeze – that’s clean surf all day. The period is still short at 8 seconds, so it won’t be a groundswell, but it’ll be fun.
Then Monday 27 and Tuesday 28 hold on. Tuesday 28 July morning shows 6 feet of ENE swell with a period of 13 seconds (long period, real groundswell) and a combined energy of 1389 (very strong energy). That’s a lot of power. At a reef, that long period could mean some beautiful, lined-up waves. The wind is a fresh cross-off (30 km/h), so it’ll be a bit windy, but the surface will be clean. That’s the one for the experienced surfers.
So, the first week is a bust. The second week, starting 23 July, builds into something good, with the best days being the 25th, 26th, and especially the 28th. It’s a long wait, but it could be a good one.

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.
