Table - best surf conditions forecast for Tennis Courts over the next 16 days.
The Lowdown
Right, let’s have a look at what’s on the cards for the next couple of weeks. The standout spot here is clearly Tennis Courts – a reef break that’s exposed to the swell, and it’s got some proper juice heading our way. The water temp is sitting about average for this time of year, so no surprises there.
We kick off Monday, September 7th, with a bit of a messy start. A risk of thunderstorms and a fresh cross-breeze from the east at 19 mph are making a lumpy mess of a 8 ft ENE swell. The wave energy is strong, clocking in at 2712, but honestly, it’s not worth paddling out for. The afternoon isn’t much better – still cross-chop and that same lumpy feel.
Tuesday, September 8th, is a write-off. Morning has rain showers and a strong onshore wind from the south at 19 mph, with a 7 ft WSW swell that’s just poor. The afternoon clears up, but the wind is cross-onshore and the swell drops to 5 ft – still not surfable.
Wednesday, September 9th, we see a small 3 ft SSW groundswell rolling in with a long 14-second period, but the wind is light and cross-onshore, putting a bit of a ripple on the face. The wave energy is moderate (521), and it’s only marginal. Not worth getting excited about.
Thursday, September 10th, is a bit of a tease. The swell is 5 ft from the ENE with a short period of 7 seconds, and the wind is cross-offshore, keeping things clean. The energy is moderate (649), but that short period means the waves will be a bit crumbly and weak. Fun for a longboard maybe, but not a standout.
Friday, September 11th, through to Sunday, September 13th, is a flat spell. Swell sizes drop below 3 ft, mostly from the SW with long periods, but the wave energy is weak (under 500). The wind is clean and cross-offshore, but there’s just no power. A few days of nothing.
Monday, September 14th, is dead quiet in the morning, but the afternoon sees a pulse of very long-period groundswell from the SW – 22 seconds! The swell is only 2 ft, but the energy jumps to 257. The wind is slight, and the conditions are clean. Glassy, but tiny.
Tuesday, September 15th, is the first real highlight. The morning is glassy, with a 2 ft SW groundswell at 20 seconds. The energy is moderate (437), and the wind is nothing. These waves will be clean, lined up, and perfect for a reef break like Tennis Courts. The long period means long waits between sets, but the quality will be there. This is a quiet, glassy session for the regulars.
Now, the real standout happens on Friday, September 18th. The afternoon delivers a solid 6 ft ENE swell, with a short period of 7 seconds, but the wind is a gentle cross-offshore breeze. The wave energy is strong (731). This is going to be punchy, clean, and fun. The short period means it’ll be a bit sectiony, but for a reef break, it’ll offer some good, fast walls. This is the best on offer in the whole window.
Saturday, September 19th, morning has a 3 ft SSW groundswell at 16 seconds, with clean conditions and gentle wind. The energy is strong (898). Another solid session, but the afternoon gets a bit cross-shore and messy.
The second week tails off a bit. Sunday, September 20th, through to Monday, September 21st, is mostly small, clean surf with moderate energy. Then Tuesday, September 22nd, morning sees a 6 ft ENE swell with an 8-second period, glassy wind, but the energy is moderate (767). It’s a promising end to the run, but with that short period, it’s more for the experienced crew.
Overall, the best windows are Tuesday, September 15th, for a glassy, long-period paddle, and the clear winner is Friday, September 18th, afternoon, for punchy, clean waves. Don’t sleep on that 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.
