The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming our way over the next couple of weeks.
We’ve got one spot on the radar, The Tree, and it’s looking like a slow burn at first with some real promise later on. The water is sitting at 86°, which is a touch warmer than normal for this time of year – nothing crazy, just a nice little bonus.
The first few days are all about small, clean waves. Friday morning, the 7th, we’re looking at a tiny 2ft SW groundswell with a long 18-second period, and it’s glassy. The energy is moderate (409). It’s small, but clean. Saturday morning the 8th, the swell bumps up a touch to 3ft from the SSW, period dropping to 16 seconds, still glassy with a light NNW breeze. The energy is moderate (493). Sunday morning the 9th is more of the same: 3ft SSW, 14-second period, glassy. These mornings are the pick of the first week, but it’s definitely small stuff. The afternoons get tricky with risk of storms and onshore wind, so stick to the early sessions.
Monday the 10th and Tuesday the 11th are similar – small morning glass with 2ft to 2ft SW swell. The energy drops a bit (231-345), but it’s rideable. The Tree is a fairly consistent spot, so there’s always hope.
Now, hold on to your board. Things start to get interesting around Friday the 14th. Friday morning we see the swell pick up to 3ft from the SW, with a long 18-second period and glassy conditions. The energy jumps to strong (883). That’s a solid morning.
But the real standout is Saturday, the 15th of August. The morning session is looking absolutely prime. We’ve got a 4ft SW groundswell, 16-second period, and it’s glassy with no wind. The combined energy is strong at 1089. This is excellent surf for experienced surfers. The Tree is exposed to SW swell, and the direction is spot on. For a break that can get crowded sometimes, this quality of surf with offshore winds will bring the crew out, but the waves will be worth the company. Anything over 5ft can be a handful for beginners, so this is one for the competent crew.
Sunday the 16th still has good energy in the morning (651) with 4ft SW swell and glassy conditions, but it’s a step down from Saturday. The following week from Monday the 17th to Saturday the 22nd keeps a consistent 2ft to 3ft of SW swell rolling through, with plenty of glassy mornings. The energy stays moderate (413-566). It’s not the big show of the 15th, but it’s steady, clean surf for the dedicated dawn patrol.
So, the bottom line: the first week is small but clean. The standout is Saturday the 15th – get on it if you can. The week after that is consistent and user-friendly. The Tree is offering up a solid run.
Rusty out.

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.
