The Lowdown
Alright folks, Rusty here with the imperial version.
We’ve got one spot on the menu for the next couple of weeks, and it’s a bit of a slow burn. The first proper surf we’re looking at kicks off on Friday the 4th of September. The overall pattern is dominated by a solid, long-period SW groundswell, but the real magic is in the mornings. The afternoons get messy with a onshore breeze and storm risks, so you’ll want to be an early bird.
The standout is The Tree on Friday the 4th of September. We’re looking at a clean 4ft swell from the SW with a very long period of 17 seconds. That’s proper groundswell energy, and with the wind glassy out of the NNE, it’s going to be perfect. The combined energy is solid (1041), so there’s plenty of push. This is an advanced wave, and with that long period, it’ll be lining up nicely. The water temp is about average for this time of year.
Saturday the 5th of September is another cracker of a morning. Same deal: clean 5ft SW swell, 16-second period, glassy conditions, and combined energy up to 1342. It’s a touch bigger than Friday, but still in that sweet spot for experienced surfers. The crowds are a possibility here, but with these conditions, who cares.
Sunday the 6th of September morning sees the swell drop a notch to 4ft with a 14-second period, but it’s still glassy and clean. The energy is lower (717), but it’s a fun morning wave.
After Sunday, the swell drops off. There’s a gap through the middle of the week with smaller, cleaner morning waves in the 2ft to 3ft range. The long period (18 seconds) on Tuesday the 8th and Monday the 14th makes the small swell feel more energetic, but it’s not a standout.
The second week is quiet. Mornings from the 12th of September onwards offer small, clean waves in the 2ft to 3ft range, but the afternoon winds kill it. The very long period swell (21 seconds) on Friday the 18th of September is interesting, but it’s only 2ft and onshore, so not worth rushing out for.
To be honest, the first weekend is the clear winner. Get on it if you can.
Rusty.

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.
