The Lowdown
Alright, Rusty here, let’s talk about what’s shaping up.
First off, water temps are sitting at 86°F which is a touch warmer than normal for this time of year, so you’ll be in boardies or a light spring suit at The Tree.
The forecast kicks off with some small, weak surf on Wednesday the 22nd. The swell is only 2ft from the SW with a 12-second period, but the cross-onshore wind and risk of thunderstorms make it a write-off. Not worth paddling out.
Thursday the 23rd morning is a tease. The swell drops to 1ft, but it’s glassy from the NNW. You’ll get a few tiny peelers, but it’s really only for the keenest longboarder. The afternoon turns poor as an onshore wind kicks in.
Friday the 24th morning is where things start to get interesting. Swell bumps to 2ft from the SW, but the period jumps to 24 seconds – that’s a very long-period groundswell. The combined energy is 681 (moderate), and with a light cross-offshore breeze, it’ll be clean. This is a standout morning for The Tree. That long period will wrap nicely around the reef, but it might be a bit straight for the beachies.
Saturday the 25th morning is another beauty. A glassy calm, 3ft of SW swell with a 21-second period, and combined energy of 656 (moderate). The waves will be clean and lined up. This is another top pick for the week.
Sunday the 26th morning holds up well. 4ft of SW swell, 19-second period, glassy NNW wind, combined energy 888 (moderate to strong). It’s a solid morning.
But the real standout is Monday the 27th morning. Swell holds at 4ft from the SW, 19-second period, but the combined energy jumps to 1191 (strong). The wind is light cross-offshore from the NNW, keeping it clean. This is the best session on offer – excellent for experienced surfers.
Tuesday the 28th morning is also excellent. 4ft of SW swell, 17-second period, combined energy 1222 (strong), and glassy conditions from the ENE. This is another top-tier morning. The afternoon gets a bit full-on with 5ft swell and onshore wind, so morning is the call.
The rest of the week into early August sees a slow decline. The swell drops to 4ft and below, with periods shortening. The energy drops from 935 down to the 200s and 300s. There are still good mornings, like Wednesday the 30th morning (4ft, 14-second period, glassy, 485 energy) and Friday the 1st August morning (3ft, 14-second period, glassy, 301 energy). But the quality is not as high as that Monday and Tuesday.
Looking further out, Saturday the 2nd and Sunday the 3rd of August are small and ordinary. There’s a gap of a few days with no real standouts until the 5th and 6th of August. Wednesday the 5th morning is small (2ft, 15-second period, glassy, 222 energy) but glassy. Thursday the 6th morning is the last highlight: 3ft of SSW swell at 15 seconds, glassy conditions, combined energy 576 (moderate). It’s a promising end to the window, but not as solid as the earlier week.
The Tree is a fairly consistent spot, but it can be crowded sometimes. The best windows are the Friday 24th, Saturday 25th, and particularly Monday 27th and Tuesday 28th mornings. After that, it’s a waiting game.
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.
