The Lowdown
Alright, Rusty here, let’s talk waves.
We’ve got a solid run of surf coming up at The Tree, but you’ve got to pick your windows. The water is a warm 86°, which is a touch warmer than normal for this time of year – you’ll be in boardies for sure.
The best of the early action is Tuesday morning, August 4th. Glassy conditions, no wind, and a clean 3 ft SSW swell with a period of 9 seconds. The combined energy is moderate (270). The offshore wind is ideal, so expect some clean, fun lines. The Tree is an exposed spot, so that SW direction is straight in. Be aware, crowds are possible here.
The pattern holds through the week, with mostly small but clean mornings. Wednesday morning the 5th offers 3 ft S swell with a glassy surface, but the period is short at 8 seconds, so the waves might be a bit weak and crumbly. Thursday morning the 6th is similar: 3 ft SSW with short period, but glassy.
Then things get interesting. Friday morning, August 7th – the swell drops to 2 ft, but the period jumps to a very long 18 seconds (groundswell). That’s a classic point break or reef setup. The combined energy is moderate (354). It will be glassy with clean conditions, but that long period can make it fat and straight at a beach break – The Tree is exposed, so it might not be the best shape here. Worth a look if you’re on a longboard.
Saturday morning, August 8th is a standout. A clean 3 ft SSW groundswell with a 16-second period, glassy, and the combined energy is strong (514). The forecast says “expect very good surf conditions.” This is your pick for the first week.
For the second week, the long-range outlook is promising but less certain. Friday morning, August 14th sees a 3 ft SW swell with an 18-second period – the combined energy is very strong (878). Glassy conditions again. This could be a cracker, but keep an eye on the forecasts.
The real heavyweight is Saturday morning, August 15th. A 4 ft SW swell with a 16-second period, combined energy of 1039 (very strong), and glassy conditions. This is excellent for experienced surfers. The swell is over 5 ft, so it’s not for beginners. The Tree will be handling that size, but with that long period, expect powerful sets.
Overall, you’ve got two standout windows: this Saturday morning August 8th, and the following Saturday morning August 15th. The Tree is fairly consistent, so keep the stoke alive.
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.
