The Lowdown
Righto, Rusty here. Let's have a look at what's on the table for the next couple of weeks.
We're looking at a solid run of South-West swell, and the water is sitting at 86°, which is a touch warmer than the average for this time of year. The Tree is the only spot on the radar, and it's a consistent performer when the swell direction lines up. This is an exposed break, and the optimum swell direction is SW, so we're in business.
The surf kicks off on Sunday the 23rd of August, but it's a bit of a tease. We've got a small 2ft SW swell and a cross-on wind, so it's not worth getting wet. The combined energy is moderate (434), but it's just not clean. The real action starts on Monday morning the 24th. It's glassy, dead calm, and there's a knee-high 2ft SW groundswell with a very long 18-second period. The energy is moderate (331), and the conditions are looking good. It's going to be a clean, fun little wave. Keep an eye on Tuesday the 25th morning too – same story, glassy, a touch bigger at 2ft, and still that long period.
The first real standout is Friday morning the 28th of August. There's a solid 2ft SW groundswell (20 second period!) and a cross-off breeze. The combined energy jumps to 539 (moderate), and the call is for very good conditions. That's a quality morning. Then Friday afternoon gets even better – the wind goes glassy, the swell bumps up to 3ft, and the energy is 570. That's a top session.
But the absolute best of the bunch is Saturday morning the 29th of August. The swell is a clean 4ft from the SW with a 16-second period. The wind is glassy, and the combined energy is a strong 1057. The forecast says excellent conditions for experienced surfers, and that's bang on. This is the one to circle. It's a bigger swell, but 4ft is a fun size for an advanced spot like The Tree. Just be aware that crowds are possible here, so get in early.
The energy drops off a bit going into early September, but there are still plenty of good windows. Thursday morning the 3rd of September looks promising with a 2ft SW groundswell and a 20-second period. The combined energy is 690, and the wind is glassy. Then things really fire up again on Friday morning the 4th of September. It's a 5ft SW swell with a 17-second period, and the combined energy is a very strong 1675. The wind is cross-off and the call is excellent for experienced surfers. That's a powerful swell, so it's for the confident crew only. Saturday morning the 5th of September is another big one – 6ft SW, glassy, and a combined energy of 1603. Again, that's expert territory.
Overall, The Tree is looking like a very solid bet for the next two weeks. The first week has a few smaller, cleaner days, but the standout is definitely Saturday the 29th of August. The second week brings a couple of bigger, more powerful swells that will be a treat for the experienced surfers.
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.
