The Lowdown
Alright, let’s break it down. Conditions ain't really firing right now or tomorrow morning, but there’s a sweet little window shaping up for Friday, September 4th, and that’s the one to circle.
The big standout is Friday morning the 4th at The Tree. You’ve got 1.3m of SW groundswell with a long 17-second period, and the wind is dead glass. The combined energy is sitting at 1041 (moderate), and it’s hitting this exposed SW spot just right. For experienced surfers, that’s a legit day. The afternoon bumps to 1.6m, but the wind goes cross-onshore, so morning is where it’s at.
Thursday the 3rd has a tiny clean morning – 0.7m, SW, 16 seconds – nothing special but rideable. Saturday the 5th keeps the swell up at 1.6m with glassy conditions in the morning, though it’s a little less consistent than Friday. Still a good call for advanced surfers.
The swell fades through the next week. Wednesday the 9th and Thursday the 10th both have clean mornings with chest-high SW swell (0.9m to 1.2m) and very long periods (16 to 18 seconds) – good shape, easy paddling. But expect company because The Tree is well-known and the wind’s favorable.
After the 12th, it gets small and inconsistent. There’s a stretch of two to three days with nothing worth recommending. Monday the 14th has a tiny 0.5m pulse of very long period SW (19 seconds) – barely log-worthy on a clean morning. After that, it’s small and marginal through the 17th.
Bottom line: for the experienced crew, Friday the 4th morning is the standout. Saturday morning is a solid second. Beyond that, it’s clean but small.
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.
