The Lowdown

Alright, folks, Rusty here. Let's have a good look at the next couple of weeks for The Tree. It's a bit of a mixed bag ahead, but there are definitely some windows where it's gonna be worth paddling out.

The immediate picture is pretty soft. We've got a small run of swell coming in for Sunday and Monday, with surf around 4ft on Sunday and dropping to 4ft by Monday morning. The energy is moderate, coming in at around 776 on Sunday. But don't get too excited just yet. Sunday afternoon the wind is set to go glassy with a touch of cross-off in the morning, which will keep things clean, but the real standout is Monday morning. The wind is dead calm, the surface will be like a mirror, and those 4ft, 13-second SW swells will be lining up nicely. It’s a great morning to be out there before the afternoon sea breeze and storm risk mess it up.

The middle of the week goes pretty quiet. Tuesday, Wednesday, and Thursday are small, with waves dropping to under 3ft. There are still some clean windows early, like Wednesday morning with a glassy 2ft and a long 18-second period, but you'll be working hard for not much. It's a good time to do other things.

Now, we get to the real action. The forecast is showing a proper pulse arriving for the first weekend of September. It really starts to build on Friday the 4th. Friday morning is looking special. We're expecting 4ft of SW groundswell but the energy is jumping, with a combined reading of 1057, which is a big step up. The wind is light and glassy from the SSE, making for what the models are calling excellent conditions. It's gonna be a proper session.

Saturday the 5th holds that size and quality, with 5ft on the face and that strong energy reading of 1219. Again, the morning is the time, with light glassy winds. This is the pick of the fortnight for sure.

After that, we settle back down a bit. We'll see a few more clean mornings with some chest-high waves, but the grind of the afternoon storms and onshore winds is a constant thing to work around. There's a lot of consistency in the swell direction and period through the second week, but the size fades. Keep your eye on those early windows, especially when the wind drops out; those clean, 3ft mornings will still offer up some fun ones.

So, if you can only get out once, make it Friday morning, the 4th. If you miss that, Saturday the 5th morning is nearly as good. Just don't sleep on Monday morning either, before it all gets a bit ordinary again.

Alright, that's the picture for The Tree. The ocean will do what it does, so keep an eye on that forecast. This is Rusty, signing off.

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.
