The Lowdown
Alright, let’s break it down. Rusty here, and I’m lookin’ at the next couple weeks for some waves.
First spot is Tennis Courts – a reef that’s wide open and likes a SSE swell. The water’s 79.9°, which is pretty normal for this time of year, nothin’ wild.
Monday morning the 27th, we got a 4.3ft easterly swell with a 14-second period and a combined energy of 923 (moderate). Wind’s from the ENE at 16 mph, but it’s cross-offshore, so the surface is clean. The catch? The wave comment says it’s marginal – tide or something’s not right. Not a standout, just a little taste.
Monday afternoon, the swell picks up to 4.9ft from the east, still 13 seconds, energy 1022. Cross-off wind, clean, but still marginal. I’d wait.
Tuesday the 28th – morning shows some life. Swell’s 7.2ft from the east, 13-second period, energy crankin’ at 1820 (strong). Wind’s still cross-off from the NE at 12 mph, surface clean. But it’s still marked as marginal. Afternoon bumps to 8.2ft from the east, same period, energy 2248 – that’s a lot of power. But at 8.2ft on a reef, that’s expert-only territory. The wind is up to 16 mph cross-off, clean, but it’s a big, mean wave. Not for the faint of heart.
Wednesday the 29th is a bust. Swell drops to 6.2ft, but the wind swings to the south at 6 mph, blowin’ straight onshore. The surface is unknown, but onshore on a reef is a mess. Afternoon is cross-on, light wind, but small ripples. No good.
Thursday the 30th – morning is a cross-shore mess with a 4.9ft east-northeast swell and a short 8-second period. Energy’s 588 (weak). The wind is cross-shore at 12 mph, makin’ chop. Skip it. Afternoon, the swell drops to 2.0ft from the SSW with a long 18-second period, but the energy is still only 580. The wind is cross-off, but it’s tiny.
Friday the 31st – morning swell is 5.6ft from the east, 8 seconds, energy 815. Wind is a fresh 22 mph cross-off – clean, but that’s a lot of wind. Afternoon, swell 6.6ft, ENE, 8 seconds, energy 1061. The wind is 25 mph cross-off. Clean, but it’s a battle. The conditions are “poor” on the afternoon, so I’d pass.
Saturday the 1st of August – morning swell hits 9.8ft from the east,

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.
