The Lowdown

Rusty here, talkin’ about Tennis Courts. This is a neat little reef setup, exposed to the swell, and it’s a tricky one for the experts only. Let’s look at what’s coming.

We’re starting off with a bit of a sleepy period. Saturday the 12th has some small, long-period SW groundswell, only 2ft, but the period is a solid 15 seconds. The water’s sitting at a warm 81°, which is about average for this time of year. The ENE wind is cross-off, so it’ll be clean, making for a few nice, lined-up waves despite the tiny size. The combined wave energy is a modest 370, so not a lot of push. This is a finesse session.

Sunday the 13th and Monday the 14th are pretty flat and poor, so don’t bother. We then see a steady build from Tuesday the 15th through Wednesday the 16th as the swell starts to pulse, with heights creeping up to 3ft and the energy jumping to 806 late Wednesday. Still, the forecast is marginal – the wind stays cross-off, but the waves are just not quite there for a proper session.

Now, hold onto your board. The best of the lot, and it’s hardly a standout, is Friday afternoon on the 18th. The swell jumps to a clean 3ft from the SSW with a period of 17 seconds, pumping the combined energy up to a strong 1060. Conditions are marked as excellent for experienced surfers. The wind from the ENE is a light 9 mph, cross-off, keeping it glassy. This is the pick of the window for a few clean, punchy waves on the reef, but you’ll need to know what you’re doing.

The rest of the run into late September is a mixed bag of small, choppy, or over-sized slop. From the 20th to the 24th, we get a bunch of short-period ENE windswell, around 6ft to 8ft, but the periods are 7 to 9 seconds – just crumbly, weak, and blown out by moderate to fresh cross-off winds. Thursday the 17th sees a 7ft E swell with a 10-second period and a 1395 energy reading, but the wind is howling at 22 mph, making it a messy, powerful beast only for the brave and the strong.

Honestly, for this 16-day run, don’t expect much. The forecast is a long, dry spell of marginal conditions. Friday the 18th is the one bright spot where it all comes together for a short while. For the rest, it’s mostly a kite-surfing show when that wind swell kicks up, ‘cause the wind is cross-off and strong.

Stay patient, keep an eye on the charts, but for now, this stretch is a write-off for anything fun.

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. 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.
