The Lowdown

Alright folks, Rusty here. Let's break down what Tennis Courts is cooking up for the next couple of weeks. I'll level with you right away – this is a tough stretch. We start with some size, but that nasty cross-off wind from the ENE just won't quit, ruining most of the good days. The only real window of hope is brief, and then it fades into a long, flat spell of small, weak leftovers.

Your best chance to score is Thursday, August 13th. It's not perfect by any stretch, but it’s the most interesting day of the whole period. We've got a 3ft to 4ft long-period groundswell from the south, running 15 to 16 seconds between waves. The energy is moderate (847 to 983). That south direction is ideal for the break, and despite a stiff cross-off breeze at 19 mph, the morning session will be the cleanest option. That’s your standout – for skilled surfers only. After that, Friday the 14th jumps to 7ft of messy, short-period ENE windswell with the wind still howling, making for poor conditions. Saturday the 15th is a full-on mess with 12ft of easterly windswell and near-gale winds – that’s expert-only and honestly looks more like a kitesurfing day than a paddle session with that wind and lumpy chop.

From Sunday the 16th right through the rest of the month, it’s a long, drawn-out run of poor to marginal surf. The ENE wind stays onshore and the swell energy drains away. We get a few glimpses – Monday the 17th morning has 6ft of short-period ENE swell, but it's marginal; then it drops to a tiny 3ft south swell in the afternoon. The last half of the forecast is mostly tiny 1ft to 3ft SSW swells with long periods (14 to 18 seconds) but weak energy under 500, meaning inconsistent, gutless waves. There's a late pulse on Friday, August 28th showing 7ft of ENE windswell, but that’s over a week and a half away, the period is a short 7 seconds, and the wind will likely still be a problem.

So here’s the bottom line: your one and only decent chance is Thursday morning the 13th. After that, it’s blown-out junk or tiny leftovers. Crowds at Tennis Courts can be a factor, but with conditions this average, you might have the place to yourself. Water temp is just about average for this time of year, nothing unusual there.

Rusty, signing off.

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.
