The Lowdown

Alright folks, Rusty here. Let's get one thing straight: there's a lot of swell on the board for The Tree over the next couple of weeks, with combined wave energy swinging from moderate to very strong. But don't go paddling out just anywhere, because the devil's in the details, especially with that tricky wind pattern.

We kick off on Friday the 21st of August, but it's a write-off. We've got a 4ft SSW swell, but it's coming in with a cross-onshore S breeze, making for a bumpy, poor surf scene. Stay on the sand for this one.

Things start to turn around in a big way on Saturday morning, the 22nd. We're looking at a 3ft S swell, and the wind goes glassy with a light NNW breeze. That's clean, lined-up, and the water's a touch warmer than normal at 87°. You could ask for a better start to the weekend.

Sunday morning, the 23rd, looks good again. The swell drops a hair to 3ft from the south, but we get a nice clean cross-offshore E breeze. The energy dips briefly but remains quite healthy. It's a solid session for Sunday.

Monday the 24th, morning glass. Dead flat wind (ESE, 0 mph), with a lingering 2ft SW long-period groundswell (18 seconds). That's a super long period, which means the Tree, being a point reef setup, should handle that beautifully, giving long, drawn-out walls. It's small but perfect. The afternoon gets choppy, though.

The pattern through to the end of the week (25th to 28th) is a bit of a mixed bag—plenty of glassy mornings with that long-period SW groundswell in the 1ft to 2ft range. But the afternoons almost always get wrecked by onshore breezes. On Friday the 28th morning, the combined swell energy bumps up to a massive 695 with a 2ft SW swell at 20 seconds... but it's cross-on. It's frustrating because the potential is huge, but it'll look better for kites than a clean surfing.

Now, here’s the standout. Circle Saturday the 29th of August on your calendar. We see a jump to 4ft of SW swell with a 16-second period, but the real story is the combined energy—it rockets up to 1053. That's powerhouse territory. The wind is a clean ESE cross-off, so the face will be smooth. It's chest to head high, powerful, and firing. This is the day for experienced surfers.

The Sunday the 30th morning is almost as good—4ft SW swell, 14 seconds, glassy conditions. Beautiful, clean surf, just slightly less punchy than Saturday. After that, we slide into less consistent, more marginal conditions until the second week rolls around.

Looking further ahead, the second week shows a lot of promise, though less certain. Thursday the 4th of September morning looks like another banger: 4ft SW swell, 17 seconds, clean cross-off wind, and sky-high energy (898). Saturday the 5th of September morning is also glassy with the same punchy 4ft SW swell. If you can gamble on the long-range forecast, those mornings look absolute gold.

The Tree is the only game in town here, but it's a good one. It can get crowded as it's a known spot, so get in early. Beginners be aware—anything over 5ft (which happens a couple of times) is going to be challenging, and those 5ft days are better left to the pros.

Stay frothy.
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.
