The Lowdown
G’day, Rusty here, and we’ve got a solid run of surf on the horizon at The Tree, a spot that really knows how to handle a south-west groundswell. This is advanced territory, so you want to be comfortable on a bigger board and know your way around a reef. The water’s sitting at 86°, a touch warmer than normal for this time of year, which is a nice bonus.
The first proper session kicks off Sunday morning, the 2nd of August. We’ve got a tiny but clean 2ft SW swell, with a period of 15 seconds – that’s proper groundswell energy, and the combined energy is a moderate 235. The wind is glassy from the north, meaning it’ll be smooth as silk. It’s small, but for a confident surfer, it’s a fun, clean start.
Monday morning, the 3rd, builds on that. Glassy again, 2ft of SW swell at 14 seconds, still that long-period goodness. Combined energy nudges up to 275. The morning will be clean, but the crowds are a possibility here, so get in early.
Tuesday morning, the 4th, is a standout. The swell jumps to 3ft from the SSW, period drops to 9 seconds – still a decent swell, and the glassy wind from the north makes it a joy. Combined energy is 299. This is the best of the first week: clean, a little more size, and that classic SW exposure working.
The rest of the week sees smaller pulses, but Thursday morning, the 6th, is worth a mention. 3ft from the south, 8-second period, glassy from the SSE, and combined energy at 229. It’s a bit short-period, but clean.
Now, look ahead to the second week. The real standout is Friday morning, the 14th of August. This is a big one: 3ft of SW swell, but the period is a massive 18 seconds – very long-period groundswell. Combined energy rockets to 664, strong. Glassy wind from the NNE. For The Tree, this long-period swell will draw right into the reef, offering powerful, well-shaped waves. Expect long gaps between sets, but the energy is serious. This is the best on offer, but it’s a week and a half away, so keep an eye on it.
Saturday morning, the 15th, follows with a 3ft SW swell at 16 seconds, combined energy at 705, glassy calm wind. Another cracker. Sunday morning, the 16th, has 3ft SW at 15 seconds, combined energy 690, clean cross-off wind. Monday morning, the 17th, wraps it up with 3ft SW at 16 seconds, combined energy 636, clean cross-off.
For the whole period, the morning sessions are the ones to chase. Afternoons get cross-onshore winds and the risk of storms, which mess up the surface. The Tree handles the SW swell beautifully, but with that long period in the second week, the waves will be powerful and the sets infrequent – perfect for the advanced crew. Crowds are a possibility, but the quality will be worth it. Don’t sleep on the 15th and 16th. Rusty out.

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.
