The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the cards for The Tree.
We’ve got a solid run of surf coming up, starting this Wednesday morning and stretching right through to the end of the month. The water’s sitting at a warm 87°, which is a touch warmer than usual for this time of year, so you’ll be comfortable in a spring suit or even just boardies.
The best of the early action kicks off Wednesday morning, the 15th, with clean 3ft SSW groundswell, a period of 13 seconds, and glassy conditions. The combined energy is moderate (430). That’s a lovely, clean start. Thursday morning, the 16th, is a carbon copy – 3ft SSW, glassy, and the energy is still moderate (428). Friday and Saturday mornings follow the same pattern: clean, small, and glassy. This is classic fun-size surf, not too big, not too small.
Now, I want to point you towards a real standout. Monday morning, the 20th of July. We’ve got a 2ft SW swell with a very long period of 16 seconds. That’s a proper groundswell. The combined energy is strong (510), and it’s glassy. The Tree is an exposed reef, so that long-period SW energy will wrap in beautifully. This is the pick of the first week.
The pattern holds through the following week, but the swell really starts to build. Friday morning, the 24th, is a cracker – 2ft SW with a 24-second period, yes, 24 seconds, clean with cross-offshore wind. The energy is strong (553). Then Saturday morning, the 25th, is glassy with 3ft SW and a 21-second period. The combined energy jumps to a very strong (779). That’s a lot of push for a small wave.
The big one, the one you circle on the calendar, is Monday morning, the 27th of July. We’re looking at 4ft SW with an 18-second period, clean cross-offshore wind, and the combined energy is a massive (1268). That's very strong energy. The conditions are rated excellent for experienced surfers. This is the best session on offer, no question. The Tree will be working perfectly. Just be aware that it’s an advanced break, and with a 4ft swell on a reef, it’s not for beginners.
There are a few afternoons with cross-on wind and risk of thunderstorms, but the mornings are consistently clean. The crowd factor is “sometimes” at The Tree, so you might have a few others out, but it won’t be a circus.
The second week sees a few more mixed conditions, but the 27th and Tuesday morning the 28th (glassy 3ft SW, 906 energy) are standouts. The very end of the month, the 30th, has some cross-shore wind and the energy drops, so the quality fades.
Overall, the outlook is optimistic. There’s surf almost every morning, and the 27th of July is a session to plan for.
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.
