The Lowdown
Alright, Rusty here. Let’s have a look at what’s shaping up for our little corner of the world.
Overall, the next couple of weeks are a bit of a mixed bag. We’ve got a couple of promising windows, but there’s a fair bit of average-to-poor conditions in between. The standout is definitely Tuesday, August 4th, with a nice, clean swell that should offer the best waves of the period. After that, the surf drops off and we go through a long, quiet spell before a possible late rally around the 12th.
The water temperature is about average for this time of year, so you’ll be fine in a spring suit.
Let’s break it down day by day. The first recommended surf is on Sunday, August 2nd, but honestly, it’s nothing to write home about. We’ve got a 8 ft ENE swell at 8 seconds, giving us moderate energy (1099), but it’s paired with a fresh 35 km/h cross-offshore breeze. The waves will be clean, but the quality is marginal. Tennis Courts is a solid reef break that’s exposed to the swell, but the short period and strong wind keep it from being special.
Monday, August 3rd, is much the same story – mornings are a little better with a 5 ft ENE swell and 25 km/h winds, but the energy is dropping (523) and the combo is still marginal. The afternoon is even worse, with poor conditions.
Now, here’s the good stuff. Tuesday, August 4th is the highlight of the whole outlook. The swell drops to 5 ft, but it’s now a groundswell with a period of 11 seconds, coming from the ENE. The combined energy is moderate (587), and the wind is a gentle 10–15 km/h, making for clean, lined-up waves. Tennis Courts will be firing, with very good surf conditions expected. The swell direction matches the optimum SSE in a general sense, and the light breeze means smooth faces. This is the day to be in the water.
Wednesday, August 5th, is still decent, but we’re on the downhill. The swell drops to 4 ft, period eases to 10 seconds, and energy is 372. Light cross-offshore winds keep it clean, and conditions are good, but it’s smaller.
Then we hit a dry patch. From Thursday, August 6th, right through to Tuesday, August 11th, the surf is mostly poor or marginal. The swell drops to less than 3 ft at times, the period is short, and the wind is a steady 25–40 km/h cross-offshore. There’s a brief spike on Friday, August 7th, with a 1 ft, 21-second long-period swell from the SW, but that’s barely a ripple and the wind is too strong. The energy is weak (311). This is a good time to take a break.
We finally get a bit of hope on Wednesday, August 12th. A long-period S swell arrives at 3 ft and 18 seconds, with moderate energy (909). The wind is still a moderate 25 km/h cross-offshore, keeping things clean. The conditions are still marginal, but it’s a step in the right direction. This swell is better suited to point breaks and reefs due to the long period, so Tennis Courts could get some nice, walling sets.
The S swell lingers through the rest of the week, with the period dropping to 15–16 seconds and the swell around 3 ft. The wind stays moderate, keeping conditions clean but marginal. The energy is still moderate (700–900 range).
Sunday, August 16th, sees a shift back to a short-period ENE swell at 6 ft, but the period is only 7 seconds, so it’s a bit of a lumpy mess. The energy is moderate (651). The conditions are marginal, and it’s more of a windswell, so expect a bumpy ride.
Monday, August 17th, is similar, with a 6 ft ENE swell and 8 seconds. The wind is lighter, but the short period and marginal conditions mean it’s still not a standout.
So, to wrap it up: Tuesday, August 4th is your best bet. The waves will be clean, shoulder-high, and well-shaped. If you can’t make it, Wednesday, August 5th, and the window around the 12th–13th offer some fun, but more marginal, options. The rest of the time, you’re better off watching the forecast or doing a bit of maintenance on your board.
Stay salty,
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.

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.
