The Lowdown

Alright, folks, Rusty here. Let's talk about what's coming down the pipeline for The Tree. It's a bit of a wait-and-see situation, but there are some real diamonds to be found if you're patient.

Overall, it’s a run of small to moderate SW groundswell, but the real story is the wind. We’ve got a stretch of absolute glassy mornings that are going to make this place shine. The energy is consistently moderate, with combined swell readings mostly in the 400s, which is a solid push for an exposed spot, peaking near 932 early on.

The first few days, Monday the 7th and Tuesday the 8th, are a write-off. Winds are onshore or cross, and the swell is small. Just surf the rips and wait.

Wednesday the 9th morning is your first real sneaky chance. The forecast says clear skies and glassy conditions. That’s a major positive. The swell is a clean 3ft from the SW, with a very long period of 16 seconds. This is proper groundswell, full of energy and shape, but that long period means it'll be lining up best along the point and reef here. The combined energy is moderate at 473. It’s not huge, but it will be clean and fun.

Thursday the 10th morning is where we hit the jackpot. We’ve got a 4ft SW groundswell, still with a long 17-second period, and it’s dead flat calm. Glass. The combined energy jumps to a strong 932. This is a standout session – the best on offer in the whole forecast window. It’s an exposed break, so it’ll be handling that energy well, and with zero wind, it’ll be as clean as it gets. Expect some crowds here though; spots this good don't stay quiet.

Friday the 11th morning is another beauty. Another full glass-off, with a 4ft SW groundswell at 16 seconds. The energy is still strong at 661. It’s a repeat of the previous day, just a touch smaller. Still a top-tier call.

Saturday the 12th and Sunday the 13th mornings are also glassy, but the swell drops off to 3ft and then 2ft. The energy drops with it. Still very fun and clean, but you can feel the pulse fading.

Monday the 14th through Wednesday the 16th mornings offer more clean, glassy windows, but the swell hovers around 1ft to 3ft. The very long periods, sometimes up to 19 seconds, return. This keeps the quality high, but the size is small. There’s a good chance of a clean little wave on those mornings.

The second week, from the 17th onward, it’s a similar story. Mornings are glassy, with a tiny 1ft – 2ft groundswell. Thursday the 17th and Friday the 18th mornings have that glassy call and a 3ft swell, worth a look for a longboard. The later mornings from the 19th to the 22nd look pretty weak and the wind starts to get shifty.

So, if you can only go once, make it Thursday the 10th morning. The Friday the 11th morning is almost as good. And don't sleep on Wednesday the 9th. The rest is a waiting game for the next proper pulse.

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.
