The Lowdown
Alright, let’s break it down in feet and all that.
We’re looking at The Tree, and it’s a slow start before things get real good.
Right now, the vibe is pretty quiet. The first session we can really talk about is Saturday afternoon, August 22nd, with a small 3ft south swell, but the wind is cross-on and it’s just not clean. You’re better off waiting.
Sunday morning, August 23rd, is where it starts to get interesting. The swell drops a touch to about 3ft from the south, but the wind shifts to a cross-off from the NNW, and it’s clean. The water temp is sitting at 87°, which is a touch warmer than normal for this time of year, so you’ll be in for a warm session. The combined energy is moderate (398), and while it’s not huge, it’s clean and rideable.
Monday the 24th serves up glassy conditions in the morning. A tiny 2ft swell from the southwest, but the period is a very long 18 seconds. That’s proper groundswell. At this size, it’ll be small but silky smooth. The combined energy is still moderate (358). The afternoons look glassy too, but with a risk of thunderstorms.
The real standout doesn’t come until Friday morning, August 28th. The swell jumps to about 2ft from the southwest, but the period is 20 seconds – that’s a very long-period groundswell. The combined energy jumps to 557 (moderate), and the wind is a cross-off from the NNW at 9 mph. The conditions are clean. This is a good one for a point break or reef setup, and The Tree is exposed to the SW, so it should line up nicely.
Saturday morning, August 29th, is the best call of the whole forecast. Swell is 4ft from the SW, still with a solid 16-second period, and the wind is glassy from the ESE at just 3 mph. The combined energy hits 884 (moderate to strong). This is clean, has some push, and the tide should be workable. The afternoon gets a bit choppy, but the morning is the one.
The following week, the swell keeps coming. September 5th, Saturday morning, is a serious standout. The swell is 5ft from the SW, 16-second period, and the wind is completely calm – glassy. The combined energy is a massive 1408 (strong). This is for experienced surfers, as it’s over 5ft, but if you’ve got the skill, this is the best session on offer. The water is still warm, and the conditions are excellent.
There’s a gap of a few days in the middle of the first week where the swell drops and the wind turns, but it never really goes flat for long. The consistency is pretty good. Crowds are possible at The Tree, but with these kinds of conditions, it’s worth the company.

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.
