The Lowdown

Alright folks, Rusty here. Let’s have a proper look at what’s coming for us at Tennis Courts. It’s a bit of a mixed bag to be honest, so I’ll walk you through the whole 16-day stretch.

Right out of the gate, we’ve got some clean but very small surf. Saturday the 12th kicks off with a 2 ft SW swell, period hanging around 15 seconds – long period groundswell, nice energy. The combined energy is moderate at 370. Winds are cross-off from the ENE at 9 mph, so it’ll be clean. Water temp is sitting at 81°, which is bang on average for this time of year, no surprises there. Gets a little smaller into the afternoon at 2 ft but still clean with a 16-second period. Not worth paddling out for though, the size is just too weak.

Sunday the 13th drops off even more. We’re looking at 2 ft in the morning and 1 ft in the afternoon – both with that lovely long period, but honestly, it’s barely a ripple. Winds stay light and cross-off. Not worth suiting up.

Monday the 14th through to Tuesday the 15th sees persistent small swell. Mornings at 1.0 ft then 2 ft, but winds pick up to 16 mph. Combined energy gets as high as 452 (moderate) Tuesday afternoon, but with 12-16 mph cross-off wind, the tidiness is marginal.

Then we hit a bit of a dud run. Wednesday the 16th to Thursday the 17th morning the swell tries to push up to 7 ft on the Thursday morning, but that’s a short-period windswell at 7 seconds from the ENE, and winds are cranking at 22 mph. The combined energy shoots to 916 (strong) but it’s messy and blown out. That’s a no-go for surfing; honestly, that setup looks more interesting for kite surfing than paddle surfing. That afternoon, still big at 7 ft with 10-second period, but winds are still fresh. Not clean.

Friday the 18th through Saturday the 19th we settle back to a more manageable 3 ft to 3 ft SW swell, periods around 16-17 seconds. That’s proper groundswell quality but the wind is still up at 19 mph in the mornings, dropping to 12 mph Saturday afternoon. Combined energy stays moderate to strong (794-966). It’s rideable but not worth shouting about.

Now, Sunday the 20th and Monday the 21st get a bit lumpy again. Swell comes up to 6 ft to 7 ft from the east, but it’s short period windswell (7-8 seconds) and winds are 19-22 mph. Strong energy but poor quality.

Tuesday the 22nd sees a similar theme: 6 ft to 6 ft from the east-northeast, period around 8-9 seconds. Energy moderate to strong, but the cross-off wind is still moderate to fresh.

Here’s the standout. Wednesday the 23rd morning is the best on offer across the whole outlook. Clear skies, light breeze from the east at 6 mph – so almost glassy. Swell of 7 ft from the east with a 10-second period, combined energy at a strong 1103. That’s a proper, clean, powerful wave for experienced surfers. It’s borderline too big for beginners, but for anyone with a bit of confidence, that is the call. Crowds can sometimes be a thing here, so expect some company.

After that glory window, Thursday the 24th is still decent at 6 ft to 6 ft east swell, but the wind picks up again. Then Friday the 25th sees the wind howling at 22 mph, dropping the quality right off.

The final weekend, Saturday the 26th and Sunday the 27th, fades back to small 2 ft SSW groundswell with 14-15 second periods, but that fresh breeze kills it. Combined energy drops to weak to moderate. Not much to chase.

Bottom line: Wednesday morning the 23rd is your best bet – clean, solid east swell, light wind. Everything else is either too small, too windy, or too messy to get excited about. But hey, it tends not to stay poor for long around here, and forecasts can change.

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.
