The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s goin’ on for this stretch.
We’ve got a solid run of surf on the cards at The Tree, a proper advanced spot that’s exposed to the southwest. This is a fairly consistent wave, but it’s one for the experienced crew – it can get a bit heavy. The water temp is about where you’d expect for this time of year, nothing weird going on there.
The real story starts Tuesday morning, the 1st of September. It’s not huge, but with a glassy 3ft SW swell and a long 13-second period, it’s clean and inviting. The energy is moderate (307), and with light SE winds making it glassy, it’s a nice little session to kick things off. Tuesday afternoon though, the wind swings onshore and the quality drops out.
Wednesday morning the 2nd looks better again – glassy conditions with a 3ft SSW swell, 13 seconds, and a bit more grunt in the water (434). It’s clean, and you’ll be stoked if you’re out there early. The afternoons keep getting chopped by afternoon storms and onshore wind, so it’s a morning-only game.
The real standout starts to build on Friday morning, the 4th of September. The swell lifts to 4ft from the SW, period holding at a solid 17 seconds, and the energy is strong (1065). Glassy conditions with ESE breeze – this is gonna be excellent for the experienced surfer. Saturday morning the 5th is even better: 5ft SW swell, 16 seconds, glassy as a mirror with NNW wind. The energy is pumping (1343). That morning window is the best on offer for the whole forecast – a proper standout session.
Sunday morning the 6th still has nice 4ft swell with 14-second period, and the wind is dead calm, glassy. Very good conditions. Monday and Tuesday mornings the 7th and 8th stay in the 3ft to 3ft range, but with glassy conditions and that long-period SW groundswell, they’re still well worth the paddle.
The pattern holds through the second week. Morning sessions from the 9th to the 13th all offer clean, glassy 3ft to 4ft SW swell, with periods up to 18 seconds. The energy stays moderate to strong (up to 777). These are reliable, clean windows. The crowds can show up sometimes at The Tree, so get in early.
By the 14th of September, Monday morning brings a different swell – 5ft from the south, but a short 7-second period. Still glassy, but that short period means the waves won’t have the same push. The 15th and 16th mornings see the SW swell return with long periods, although the size drops to 2ft–3ft.
Overall, the pick of the bunch is Friday the 4th and Saturday the 5th mornings. Bigger swell, clean, glassy, and loads of energy. That’s the one you want to circle on the calendar.
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.
