The Lowdown
Alright, let’s get into it.
We’ve got a run of surf ahead that’s worth paying attention to, but it’s got its own rhythm. The first couple of days are okay, not gonna blow your mind, but there’s a real push of energy that builds into the first Friday. That’s when things get properly fun. After that, it settles back down, and the second week is more about picking your moments, with some glassy windows that are definitely worth grabbing. The standout period is that first Friday and Saturday morning, no question.
Right now, The Tree is the only spot in the game, and it’s picking up a decent SW groundswell. Saturday morning, we start with clear skies and a light offshore breeze. There’s clean 4ft surf with a long 16-second period. The energy is moderate at 918, but the conditions are spot on. It’s a pretty good start, but it’s the calm before the main push.
The afternoons this week are all about the sea breeze kicking in onshore, and with a storm risk, it’s not where you want to be. The swell is there, but it gets messy. Sunday morning sees the wind drop to nothing, leaving it glassy with 4.3ft of SW swell at 14 seconds. That’s a sweet window. This is also where I’d call out the water temp – it’s right about average for this time of year, so don’t stress about a wetsuit change.
The start of the new week, Monday through Wednesday, has some surf but it’s smaller, dropping down to around 2.6ft. The mornings are glassy and clean, but the energy is weak, and honestly, it’s more of a longboard or grovel board session. Not much push there.
Then we get to the good stuff. Thursday the 4th of September, the swell starts to fill back in, and Friday the 5th is where it’s at. Friday morning is looking excellent for experienced surfers. The Tree will be seeing a solid 5.2ft of SW swell with a 17-second period. That’s proper groundswell, and the energy is strong, hitting 1592 on the combined scale. With light, glassy conditions, this is the pick of the whole forecast. It’s an exposed break, so it’ll handle this size, but it will be a step up from the earlier days. This is the one to circle on the calendar. Saturday morning is right there with it too, another 5.2ft of SW at 16 seconds and clean, glassy conditions.
After that, it slowly fades. The second week brings smaller, cleaner waves, mostly in the 3ft to 4.3ft range. There’s a few magic moments, like the 10th of September morning with a clean 4.3ft of SW, and the 11th looks good too. But these are smaller, more relaxed sessions compared to that first Friday buzz.
Keep in mind, this is an advanced spot, and it’s fairly consistent. It’s exposed, so it gets all the swell. You might have company on the good days, but it’s a spot that handles the energy well. With the long period swells, it can be a bit straight at times, but the good winds will keep it lined up.
Let’s talk about the plan. If you can only get one surf in, make it the morning of Friday, September 5th. The conditions are looking prime, and the swell is there. The Saturday before it is also a solid backup. Otherwise, keep an eye on the glassy mornings in the second week; they’re worth the paddle out even if it’s smaller.
Stay stoked.

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.
