The Lowdown
G'day, I'm Rusty. Let's have a look at what's on offer for the next couple of weeks.
We've got a cracking little run of small but clean surf coming up, all at The Tree. There's a bit of a gap at the start, but nothing to worry about – the first decent session kicks off Thursday morning, July 30. The water is a touch warmer than normal for this time of year, sitting at 86°, so that's a nice bonus.
The standout for the whole period? That's got to be Saturday morning, August 8. We're looking at a clean 3 ft SW groundswell with a 16-second period, and the wind is dead glassy from the north. The combined energy is pumping at 502 (moderate wave energy), and with the swell direction right in the sweet spot for this exposed SW spot, it's going to be a top morning. The Tree is an advanced break, so it's not for the faint-hearted, and it can get crowded sometimes, but with conditions like this, it'll be worth jostling for a wave.
Thursday morning, July 30, is also a ripper: 4 ft of SW swell at 14 seconds, glassy NNE wind, and combined energy of 489 (moderate wave energy). The session will stay clean into the morning, but the afternoon turns cross-on from the south, so make the most of the early.
Friday morning, July 31, is more of the same: 3 ft SW swell, glassy north wind, and 296 energy. Clean and fun. Saturday morning, August 1, drops a little to 2 ft, but still glassy and clean. Sunday morning, August 2, is small at 2 ft but with a very long 15-second period and glassy conditions – that super long period can make it break a bit straight at a beach setup, but The Tree is a reef, so it should handle it nicely.
Monday morning, August 3, is tiny at 2 ft but dead calm and glassy. Tuesday morning, August 4, bumps up to 3 ft SSW swell with a shorter 9-second period, but with zero wind and glassy conditions, it'll be fun enough. Wednesday morning, August 5, is ordinary – 2 ft S swell at 8 seconds and only 128 energy – it's surfable but nothing to write home about. Thursday morning, August 6, is similar, with a risk of thunderstorms.
Then we hit the real gold. Friday morning, August 7, brings a 2 ft SSW groundswell with a very long 18-second period and 413 energy, glassy north wind. Not huge, but that period will create some beautiful lines. Saturday morning, August 8, is the pick as I said. Sunday morning, August 9, is a solid 3 ft SW swell at 14 seconds, glassy, with 369 energy. Monday, August 10, and Tuesday, August 11, are both small but clean mornings. Wednesday morning, August 12, has a 2 ft SW swell with a whopping 19-second period and 402 energy – again, very long period, but The Tree is a reef, so it'll handle it.
The absolute standout is Thursday morning, August 13. We're looking at 3 ft SW swell, 17-second period, dead calm easterly wind, and combined energy of 634 (moderate wave energy). That's the best on offer. Friday morning, August 14, is also a beauty: 3 ft SW swell at 16 seconds, 600 energy, and glassy. Both mornings are for the experienced crew, and they'll be remembered.

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.
