Table - best surf conditions forecast for The Tree over the next 16 days.
G’day, Rusty here. We’ve got a solid run of small but clean swell coming up at The Tree, stretching through the next two and a bit weeks. It’s not gonna be a thumping session, but the consistency of these glassy mornings is a real treat for a spot like this. The water’s sitting at 86°, which is a touch warmer than usual for this time of year.
We kick off on Sunday, 12 July, but it’s not really one to get excited about. The morning’s a bit messy with a cross breeze and only 3ft SSW swell. The afternoon gets worse with onshore wind and storm risk. Best to hold off.
Monday, 13 July is where it starts to turn. Morning glass-off, zero wind, with a clean 3ft SSW swell rolling in. Period’s a solid 13 seconds, so there’s some energy in the water – moderate wave energy (446). The afternoon stays glassy with a light SS wind. This is a good one to get wet.
Tuesday, 14 July morning keeps the glassy theme going, with 3ft SSW swell and a 14-second period. The energy is moderate (416). The afternoon turns cross-on, so stick to the early.
Wednesday, 15 July morning is another glassy beauty with 3ft SSW swell and 13 seconds. Energy’s moderate (430). The afternoon gets a cross-on breeze and a storm risk, so morning windows are the go.
Thursday, 16 July – dead calm in the morning, glassy as glass, with a 3ft SSW swell at 13 seconds. Energy moderate (428). This is a standout morning if you can get out.
Friday, 17 July morning is light and glassy with 2ft SSW swell, but the period is still 14 seconds. Energy’s a bit lower (379) but the clean conditions make up for it. The afternoon gets a cross-on wobble.
Saturday, 18 July morning: glassy, 3ft SSW swell, 12-second period. Moderate energy (379). Another solid morning.
Sunday, 19 July – dead calm again in the morning, 3ft S swell with a 14-second period. Energy’s moderate (436). The afternoon gets a bit of a cross-on bump, but that morning is a gem.
Monday, 20 July morning is the first real standout. Clean cross-off wind, 3ft SSW swell, 13-second period, and the combined energy jumps to 601 (moderate strong). The forecast backs this one as very good. The afternoon gets onshore and stormy, so don’t sleep in.
Tuesday, 21 July morning: glassy, 3ft SW swell, long 15-second period. Energy is 510 (moderate strong). That’s a long-period groundswell – it’ll offer some nice lines but might be a bit straight for a beach break. The afternoon gets heavy rain and clean offshore wind, but the swell drops.
Wednesday, 22 July morning: glassy, 3ft SSW swell, 12-second period. Energy moderate (463). Afternoon turns cross-on. Good morning.
Thursday, 23 July – the energy drops. Morning’s glassy but the swell period has dropped to 8 seconds, and energy is just 188 (weak). The afternoon is even weaker. This is a day to take a break.
Friday, 24 July – a bit of a bump in size to 4ft SSW, but period is short at 9 seconds and the wind is cross-shore. Energy 307 (weak). Not great.
Saturday, 25 July morning: glassy, 3ft S swell with a 11-second period. Energy 324 (weak). The afternoon gets cross-on.
Sunday, 26 July morning: dead calm, glassy, 2ft SW swell with a very long 19-second period. Energy 382 (moderate). That’s a proper groundswell – it’s gonna be super clean but the sets will be spaced out. The afternoon turns onshore.
Monday, 27 July morning is the true standout of the entire run. Glassy, 3ft SW swell, an 18-second period, and the combined energy hits 724 (moderate strong). That’s the biggest energy reading of the period. The afternoon gets a cross-on wind, but that morning session looks like the best of the bunch – clean, long-period, and decent energy.
Crowds can pop up here sometimes, so don’t expect to have it all to yourself, especially on the glassy mornings.
All in all, the first week has plenty of early-morning glass-offs with consistent 3ft-ish SSW swell. The second week is a bit more variable, with a couple of weak days around the 23rd and 24th, but the 27th is a ripper worth planning for. No huge size, but for a spot that’s fairly consistent, you’ll get waves most days.
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.
