Table - best surf conditions forecast for The Tree over the next 16 days.
Alright, Rusty here, let's break down what we've got.
We're only looking at one break, The Tree, and it's shaping up to be a pretty consistent stretch for the experienced surfer over the next couple of weeks. The water temp is sitting at about 86°, a touch warmer than normal for this time of year.
We kick off on Thursday, July 9th. The morning is the real window – we're talking glassy conditions, a light NW breeze, and a clean 3ft SSW groundswell. With a 15-second period, there's plenty of energy behind it (combined energy of 500). It's not going to be massive, but the quality will be top-notch, likely the best we see. Just watch for thunderstorms and a light onshore wind messing up the afternoon.
Friday the 10th looks similar, just a touch smaller at 3ft. Get it in the morning before the arvo change.
Into the weekend, Saturday the 11th and Sunday the 12th, the swell hangs in around 3ft to 4ft, but the wind turns more cross-shore, so it won't be quite as clean.
The following week, from Monday the 13th to Saturday the 18th, the game plan is the same – mornings are your friend. A real standout is Saturday the 18th morning. We're talking dead calm wind, a glassy ocean, and the biggest swell of that run at 4ft. That's going to be a session to remember for those who can get out there.
As we move into the final week, we get another good pulse on Tuesday the 21st morning. It's a 4ft SW swell with a 15-second period, clean offshore wind, and a combined energy of 737. That's got some real power and will offer some quality waves.
The last few days, the 23rd and 24th, fade out. The swell drops to under 2ft, and the period shortens. The morning of the 24th is glassy on a 2ft wave, but it's barely worth the paddle.
So, my top picks? Thursday the 9th morning and Saturday the 18th morning for the perfect glassy conditions. For a bit more grunt, Tuesday the 21st morning is a solid bet. Remember, The Tree is for the advanced surfer, and it can get a bit crowded at times.
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.
