The Lowdown
Alright folks, Rusty here, and let’s have a yarn about what’s cooking at The Tree over the next couple of weeks. The opening window is a bit touch-and-go, but get ready to circle a few dates on the calendar.
First up, Thursday afternoon (27 August) is pretty ordinary – small 1ft SW swell, a weak energy reading (215), and cross-onshore winds mean it’s a skateboard day. The water is sitting at 86°, which is a touch warmer than normal for this time of year.
Come Friday morning (28 August), things perk up. That SW groundswell bumps to a tidy 2ft with a very long 20-second period, pumping out moderate wave energy (543). The real story is the glassy conditions – flat calm, offshore NNE breeze. It’ll be super clean, though with only knee-high waves, it’s more about the peace and quiet than power.
The standout session is shaping up for Saturday morning (29 August). We’re looking at a solid 4ft of SW swell, 16-second period, pushing strong wave energy (932). Clean glass with a light offshore NW wind. Conditions will be excellent. Keep an eye on the crowd factor though – it’s exposed and can get busy when it’s good.
Sunday morning (30 August) delivers again with 4ft SW swell, 14-second period, and a dead calm (0 mph) NNW breeze – glassy perfection. Wave energy is still strong at 789. That’s a top contender for the best of the first week. After lunch, the seabreeze kicks in and makes it messy.
The following week gets more promising again. Monday (31 August) and Tuesday (1 September) are a write-off with deteriorating conditions and small swell. But then on Thursday morning (3 September), we get a surprise: a glassy, 2ft SW groundswell with 16-second period. It’s a sneaky clean one for those who can duck out.
The real highlight of the whole forecast lands on Saturday morning (5 September). That’s the big one: 5ft of SW swell, 16-second period, and an energy reading of 1201 – strong stuff. Glassy, dead calm, with no wind. The file flags this as excellent for experienced surfers, and it’s no wonder. This is expert territory at that size, so leave the soft-top at home. The consistent SW groundswell and long period mean nice lines peeling down the point. Crowds are possible given the quality.
Later, on Thursday morning (10 September), we see a 5ft SW swell with 16-second period, but light cross-shore winds will put a slight wrinkle on the face. Still, strong energy (1092) and a fair chance at a decent wave. Then Friday morning (11 September) offers another glassy window with 4ft SW at 15 seconds, clean and inviting.
For the second week, it’s a mix of glassy mornings and onshore afternoons. The standout remains that Saturday (5 September) morning – don’t sleep on it. Beyond that, the pattern of morning clean-ups continues, but the energy drops off toward the end. Keep an eye on the charts, but for now, that Saturday is the one.

Information about the The Tree Surf forecast
The above surf forecast table for The Tree provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at The Tree can be found by selecting the local surf guide option on the grey menu. Our The Tree 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 (The Tree) 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 The Tree 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.
