The Lowdown
Alright, Rusty here. Let's take a look at what's on the menu for the next couple of weeks.
Overall, it's a bit of a slow burn but there's some real quality hiding in the back half of the forecast. We've got a solid south-west groundswell building, and the key is going to be timing it with the right wind. The Tree is our only spot on the radar, so all eyes are on it.
We kick off Monday afternoon, the 20th of July, with marginal conditions. A light SSE cross-breeze and a small 3ft SW swell, but the energy is moderate (549) and the water is a touch warmer than normal at 86°F.
Tuesday the 21st is where it starts to get interesting. The morning looks clean with a light NE offshore breeze, that same 3ft SW swell, and a solid 15-second period. The energy is moderate (463). The afternoon turns onshore, so get out early.
Wednesday the 22nd is a gem. A glassy morning with a light northerly, zero wind, and 2ft of SW swell. It's small, but the energy is still moderate (295) and the conditions will be perfect. The afternoon stays glassy but the swell drops a touch.
Now, listen up. The real standout is the morning of Thursday the 24th of July. We've got a 2ft swell, but check out the period: 24 seconds from the SW. That's a very long-period groundswell. The combined energy is strong (560) and the wind is completely calm, glassy. It's a day for a longer board, but the waves will be clean and lined up. The Tree is a reef setup, so this long-period energy will wrap in beautifully.
The next morning, Friday the 25th, is also top-tier. Another 3ft SW swell with a 21-second period, the energy is pumping (694), and the wind is a light offshore. The sets will be a bit more spread out, but the quality will be worth the wait.
The 27th of July, Monday morning, is a big one for experienced surfers. The swell is up to 4ft from the SW, with a 19-second period, and the energy is very strong (1215). The wind is glassy. This is proper, powerful groundswell. The Tree is an advanced break for a reason, and this will be the peak of the swell.
The 29th of July, Wednesday morning, is another excellent call for the advanced crew. 5ft of SW swell, 16-second period, very strong energy (1032), and glassy wind. The size is getting up there, so it's not for the faint-hearted.
The first week of August sees the swell ease back, but there are still clean windows. The 4th of August, Tuesday morning, offers a 4ft S swell with a 15-second period and a glassy start. The energy is strong (789), and it's a good option for the start of the new month.
To wrap it up, the absolute best of the bunch is the morning of the 24th of July for that ultra-long, clean groundswell, and the morning of the 27th of July for the biggest, most powerful swell of the period. Both require a bit of planning, but the payoff will be huge.
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.
