Table - best surf conditions forecast for Tennis Courts over the next 16 days.
Alright, Rusty here. Let’s have a look at what’s on the cards for Tennis Courts (Tennis-Courts) over these next couple of weeks. Straight up, the first few days are a write-off. There’s a solid stretch where you’d be better off doing anything else. We’re looking at a run of poor surf starting July 7th, all the way through to the morning of July 11th. The swell is coming in from the ENE, which isn’t what this reef wants – the optimum is SSE – and we’ve got a fresh cross-off shore breeze blowing at 22 mph that’s just killing any chance of quality. Swell heights are between 5.6 ft and 7.2 ft with a short, weak period of just 7 to 8 seconds, so the wave energy is pretty average for the size (mostly between 461 and 778 in the combined energy). The water temp is sitting at 79.7°, which is pretty much normal for this time of year.
From the afternoon of July 11th through to the 20th, things lift a little but still nothing to get excited about. We’re into “marginal” territory. The swell stays in that 5.6 ft to 7.2 ft range, wind is still a persistent cross-off from the ENE, and the period is short. The scores are only just scraping a 1 or a 2 out of 10. The combined energy climbs up – we see some readings in the 700s and 800s – but the wind and swell direction means it’s just messy. This reef setup might look a bit more interesting for kite surfing than paddle surfing during this stretch.
The one true standout, the best on offer, is the morning of July 21st. This is over a week away now, so treat it as promising but far from locked in. The swell is coming from the E at 3.6 ft with a long period of 16 seconds – that’s proper groundswell energy. The combined energy jumps to 1284, which is strong. Now, a long period like that can make a beach break sectiony, but on a reef like Tennis Courts it could shape up nicely. The wind is a moderate cross-off at 12 mph from the ENE, which will keep the surface clean. This is the session to have your eye on, but remember, the swell direction is off-optimum, so the quality might not be perfect. It’s an advanced wave at 3.6 ft, so it won’t be too big for the crew. Crowds are sometimes a problem here, so you might not have it to yourself.
The following morning on July 22nd still has that long-period groundswell from the E at 3.6 ft (15 seconds), but the combined energy drops to 929, and the wind swings to a gentle cross-on from the ESE, making the surface a bit choppier. It drops off from there.
So, bottom line: the next week and a half is pretty grim. The only real highlight is that Tuesday morning on July 21st. Keep an eye on the forecasts, but don’t hold your breath on the early days.

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.
