The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s coming our way for the next 16 days. There’s only one spot that’s got anything on offer, so we’ll be zeroing in on it.

The overall pattern is actually pretty promising. We’ve got a steady stream of solid SW groundswell hitting the exposed spots, and a few windows where the wind plays nice. The standout session is hands-down Saturday, 29 August, with a glassy morning and a proper 4ft of SW groundswell, period hanging around 16 seconds. That’s a long-period groundswell, meaning good energy and shape, but at this break, being a reef/point setup, it’s ideal. The combined energy is strong at 1003, so there’s some push behind it. Water temp is sitting at 86°, which is a touch warmer than normal for this time of year, so you might not need the thickest rubber.

Let’s run through the rest. Monday afternoon, 24 August is a write-off with onshore SW wind and only 2ft. Tuesday, 25 August morning is a little gem – glassy conditions with the wind going north 5 km/h, 2ft of clean SW groundswell, but don’t expect much power (210 energy). It’s small but clean.

Wednesday, 26 August and Thursday, 27 August are pretty forgettable – onshore winds or messy sideshore conditions for most of it, with the swell dropping to 1ft at times. Friday morning, 28 August shows some life: 2ft with a very long 20-second period and a cross-off breeze from the NNW. The combined energy jumps to 543, so there’s some grunt. That’s one to watch if you can get out early.

Then we hit that Saturday, 29 August morning I mentioned – the pick of the whole run. Glassy, 4ft, 16-second intervals, strong energy. The afternoon gets onshore and bigger at 5ft, which might be pushing it for beginners but still fun for advanced guys.

Sunday, 30 August morning is another good one: glassy easterly breeze, 4ft of SW groundswell, though the period drops to 14 seconds. The crowd factor at The Tree is “sometimes”, so you might have company, but it won’t be a circus. Monday, 31 August morning is calm, glassy with 4ft – a solid option for a quiet session.

Into September now: Tuesday morning, 1 September is glassy again, but the swell is dropping to 3ft. Afternoon sees the wind swing onshore, so get in early. Wednesday, 2 September and Thursday, 3 September are mostly messy with cross-onshore winds, but Friday, 4 September morning is a beauty: no wind, glassy, 5ft of SW groundswell pumping at 18 seconds, with combined energy of 1411. That’s a proper swell. It’s big enough that only experienced surfers will be comfortable – over 5ft is a step up. The afternoon picks up to 5ft with cross-onshore wind, so the morning window is the one.

Saturday, 5 September and Sunday, 6 September mornings both offer glassy conditions, 4ft to 4ft of clean SW swell. Monday, 7 September morning is clean again with a cross-off breeze, 4ft. Tuesday, 8 September morning rounds it out with glassy wind and 3ft.

So, to boil it down: the best bets are the mornings of Saturday, 29 August and Friday, 4 September. Both offer clean glass, decent swell size, and long-period energy. Get out there early. Rest of the time, there are plenty of smaller clean windows mid-week, but don’t expect barrels. Just fun, manageable waves.

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.
