The Lowdown
G’day, I’m Rusty, and I’ve been looking at the charts for The Tree. This spot is an exposed SW break for the advanced crew, and it’s got a bit of everything over the next couple of weeks. The first few days are weak, but there are some real standouts coming. The water’s warm at 86°F, which is a touch warmer than normal for this time of year.
Tuesday afternoon, August 25, is a pass: tiny 2ft SW swell with a cross-on south wind at 6 mph. The energy is weak at 204. Wednesday morning the 26th is glassy with a north breeze at 3 mph and clean 2ft SW groundswell (15 seconds). Still small, but surfable. Wednesday afternoon turns ugly with 3ft S windswell and onshore wind.
Thursday morning the 27th is a little gem: 1ft SW groundswell with a long 18-second period, clean cross-off wind from the NNW at 6 mph. Energy is moderate at 254. Tiny but clean. Thursday afternoon gets sloppy with 4ft SSW windswell.
Friday morning the 28th is where it picks up: 2ft SW with a super long 20-second period, clean cross-off north wind at 3 mph, energy at 541. The sets will have some punch. Friday afternoon stays rideable but gets a cross-on breeze.
Saturday morning the 29th is a standout: glassy, zero wind, and clean 4ft SW groundswell at 16 seconds. Strong energy at 929. Dawn patrol will be pure glass. Saturday afternoon gets lumpy but the swell pushes to 5ft—good for the experienced.
Sunday morning the 30th is another beauty: glassy, 4ft SW swell at 14 seconds, strong energy at 798. Perfect. Sunday afternoon is spoiled by a light onshore.
Monday morning the 31st is glassy with 4ft SW groundswell. Clean and fun. The rest of the week is marginal through Thursday morning September 3.
Friday morning September 4 is the standout of the whole run. Glassy, light air from the NNW, and 4ft SW groundswell with a 17-second period. Very strong energy at 1211. Excellent for experienced surfers—clean and powerful. Crowds are possible here, so get in early.
Saturday morning September 5 has 5ft SW but with a cross-shore breeze—energy at 1035, less clean. Sunday afternoon September 6 is glassy with 4ft SW at 14 seconds.
Second week, September 9 Wednesday morning is another cracker: glassy, 4ft SW groundswell at 19 seconds, excellent energy at 1055. Excellent conditions for experienced surfers again. A promising long-range call.
The Tree’s best windows are Friday morning September 4 and Wednesday morning September 9. Go get it.
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.
