The Lowdown
Alright, Rusty here. Let's have a look at what's cookin' over the next couple of weeks.
G'day, it's a bit of a slow-burner for the next few days, but there's some real magic lining up for the back half of the run. The water is a touch warmer than normal for this time of year, sittin' at 86°, so you can leave the thickest rubber at home.
The Tree is the only spot on the cards here, and it's an exposed, advanced-level reef or point break that needs a solid SW groundswell to get going. It's fairly consistent when the swell hits, but it's a spot that can be a bit fickle.
Right now, for Thursday the 6th, we've got a small 3ft S swell with a short 8-second period, which is weak sauce. The combined energy is only 254, so it's a bit limp. Early morning is glassy though, with a bit of heavy rain, so it's clean but tiny. That afternoon the wind shifts and the surf drops to 3ft, so it's a write-off.
Friday the 7th is a real tease. The morning brings a tiny 2ft glassy wave, but wait – the period jumps to 18 seconds from the SW, and the energy spikes to 414. That's groundswell, but it's just too small to do anything with in the morning. The afternoon has a clean 2ft wave with a 17-second period, but the wind is directly onshore, so it's a messy mess.
Saturday the 8th and Sunday the 9th are more of the same – small, clean mornings with 3ft of SSW swell, but the period is still long (14-16 seconds) and the energy is moderate, around 300-400. It's a good sign for things to come, but you're not going to get a proper ride just yet.
The real standout is the morning of Friday, August 14th. We've got a 3ft SW swell but the period is a massive 19 seconds, and the combined energy is a whopping 803. The wind is glassy calm, making it clean as a whistle. This is a long-period groundswell that will set up beautifully at this kind of break, but it's a bit tricky for a beach break. The afternoon gets a bit bumpy with onshore wind, but the swell bumps up to 4ft and energy hits 1214 – that's serious power.
The absolute best of the whole run is Saturday morning, August 15th. The swell is 5ft from the SW, period is 16 seconds, and energy is 1194. The wind is dead calm, glassy, and the conditions are rated excellent for experienced surfers. This is the one to circle on the calendar. It's a punchy, clean groundswell that will have some proper welter to it. For the advanced crew, this is the session.
The following week sees a slow drop-off, with mornings on Monday the 17th and Thursday the 20th offering clean, glassy 3ft to 3ft waves with good energy and period, but nothing that matches the peak of the 15th.
Crowds can be a factor here sometimes, so for that Friday and Saturday morning, expect some company. But for the quality on offer, it's worth it.
Stay salty.
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.
