The Lowdown
Alright folks, Rusty here. Let’s get into it. We’ve got a 16-day window, and to be honest, the first week is a bit of a grind. We’re looking at the Tennis Courts, an exposed reef set-up that needs a clean SSE swell to really fire. The opening days are a tough watch.
The first few days are a write-off. Tuesday the 4th and Wednesday the 5th have some small, weak swell coming from the ENE, but the wind is a persistent cross-off. The wave energy is low (561 and 315) and the commentary says it’s marginal at best. Thursday the 6th through to the start of the second week just get worse – the surf quality drops to poor, and the swell becomes a mix of tiny, long-period south energy that just doesn’t suit the break. The combined energy stays weak to moderate (151 to 619). You’d be better off waiting for the next favourable weather pattern.
Now, there’s a glimmer of hope. The period from Saturday the 15th through to Monday the 18th is where the real story is. We get a solid pulse of ENE groundswell building up. Saturday the 15th sees 7.2ft to 7.5ft from the ENE, but the period is a short 8 seconds, so it’ll be a bit messy. The wave energy jumps into the strong range (780 to 905).
The standout, without question, is Monday the 17th. The morning brings a pumping 11.5ft swell from the ENE with a period of 9 seconds, and the combined energy hits a massive 2756. This is expert territory – over 8.2ft, so only the crew with the biggest balls and the best skills should be out. The wind is a clean cross-off from the ENE, so the waves will be lined up. The water temperature is a warm 80.6°, which is about average for this time of year, so a spring suit is fine. Keep in mind, the Tennis Courts can get a crowd sometimes, but on a Monday with that much size, it may thin out the pack a bit.
Tuesday the 18th drops off a bit to 8.2ft, still solid, but the energy is fading. After that, we’re back to small, weak south swells. So, the one real stand-out is Monday the 17th. Get your skis ready.

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.
