The Lowdown
Alright, let’s get into it. I’m looking at the charts for the next couple of weeks and, honestly, it’s a bit of a slow burn. There’s surf on the way, but you’re going to need some patience.
The first decent window doesn’t open up until Sunday, July 19th, so you’re looking at about five days of pretty ordinary conditions before anything worth paddling out for shows up. A lot of that early week has us with poor surf conditions, a stiff cross-off wind from the ENE, and swell that’s just not doing the job. Not a great start.
Alright, let’s talk about the one spot that has the best chance of giving us something clean and fun: Tennis Courts. This is a reef break that’s exposed to swell and, crucially, needs the direction to line up right. The optimum swell direction here is SSE, so keep that in mind.
The first real glimmer of hope is Sunday, July 19th. We’ve got a bit of swell pushing in, around 5.9 ft from the ENE in the morning, dropping to 4.9 ft in the afternoon. The period is short, around 8 seconds, so it’s windswell, not the cleanest groundswell. The wind is cross-off from the ENE at 19 mph, which will keep the surface clean, but that short period will make it a bit lumpy and hard to get into. The combined wave energy is starting to build, hitting 562 in the morning (moderate energy) and 515 in the afternoon. You could get a few waves, but it’s not going to be epic. It’s a marginal call.
Monday, July 20th is similar. Morning surf around 4.6 ft from the ENE, with the wind easing to 16 mph. Still cross-off, still clean. The energy jumps up to 580 in the morning. The afternoon sees the swell drop to 2.6 ft, but the direction swings to the S and the period jumps to 16 seconds. That’s a proper groundswell, but it’s small. The energy is up at 599, so there’s some push, but the size is lacking.
Now, Tuesday, July 21st is the first day that starts to look interesting. The swell is still small, 2.9 ft from the S, but the period is 14 seconds. That long period is a big deal. It gives the waves shape and power. The combined energy hits 693 in the morning and 701 in the afternoon. That’s solid moderate energy. The wind stays cross-off from the ENE at 16-19 mph, keeping it clean. This is your first real window for a fun, chest-high session on a long-period groundswell. The water temp is about average for this time of year, so just a normal summer suit.
The energy continues to climb through the week. Wednesday, July 22nd sees energy at 658 in the morning, with a 2.6 ft S swell and a 13-second period. The afternoon gets a 1.3 ft, 23-second period SSW swell. 23 seconds? That’s an incredibly long period groundswell. It will have heaps of energy but the sets will be few and far between. It’s a small wave, but if you catch it, it’ll be a long, smooth ride. The energy is 691.
Thursday, July 23rd brings a bigger bump in energy, hitting 831 in the afternoon with a 4.6 ft ENE swell and an 11-second period. The wind is still cross-off from the ENE at 19 mph. That’s a bit more size, but the period is shorter, so it’ll be a bit more mixed.
The standout in the whole forecast is Friday, July 24th through Sunday, July 26th. The combined energy is getting serious, with values starting at 902 on Friday morning, peaking at a very strong 1081 on Friday afternoon, and staying high through the weekend at 922 and 942. The swell direction is swinging to the E, and the period is a lovely 15-17 seconds. That is a proper long-period groundswell. The swell height is 3.3 ft to 3.6 ft. With that long period and clean cross-off winds, you’re looking at incredibly clean, well-shaped waves. This is the best on offer. Friday afternoon looks like a standout session, but the whole weekend is promising.
Monday, July 27th still has clean 2.9 ft E swell with 14-second periods and energy in the 600s. The wind eases to a gentle breeze from the ENE at 9 mph. That’s glassy. Very nice.
The last few days, July 28th and 29th, the energy drops off a bit, but the wind becomes light and variable. Tuesday afternoon has a clean 2.3 ft E swell with 12-second period and a light breeze. Wednesday morning sees a bigger, short-period 5.2 ft ENE swell with light wind. It’s clean, but that 7-second period will make it choppy and hard to ride. The break is a reef, so long-period swells are best here, not these

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.
