The Lowdown
Alright folks, Rusty here with the outlook for The Tree. This place is exposed to the southwest, and it’s a pretty consistent spot for the advanced crew, though it can get a bit of a crowd sometimes.
Water temp is sitting at 86°, which is a touch warmer than usual for this time of year. We’ve got a sweet little run of surf coming up, starting on Thursday, July 16th. The swell is from the SSW, around 3ft, with a period of 13 seconds, giving us a moderate wave energy (428). The morning is absolutely glassy with a light NNE breeze, so the conditions will be clean. This is a standout for the near term – clean, lined-up groundswell.
Friday morning, July 17th, is also looking good, with glassy conditions again and a clean 3ft SSW swell. The energy is still moderate (376). Saturday morning, July 18th, keeps the run going with glassy conditions and a 2ft S swell. The period is a bit longer at 14 seconds, which is good for shape, but the energy is moderate (393). The wind is a light NE, so it’ll be clean. The afternoons all week are getting cross-onshore winds and a risk of thunderstorms, which messes up the surface, so stick to the mornings.
The quality and consistency really get a boost late in the month. Starting Monday, July 27th, the swell is from the SW at 4ft, with a period of 18 seconds. This is a very long period groundswell, and the energy is strong (1611). It’s glassy calm in the morning, making for excellent conditions for experienced surfers. This is the standout of the whole outlook. The Tree at this size with that long period and glassy wind will be delivering some serious lines.
Tuesday, July 28th, is another morning standout. The swell is 5ft from the SW, period 18 seconds, with a very strong energy (1440). Calm conditions and glassy surf will make for an epic session. The water is still that touch warmer than normal.
After that, the swell starts to drop off slightly, but we still have clean mornings with good surf. Wednesday, July 29th, has a 4ft SW swell with a 16-second period, glassy winds, and very good conditions. The energy is solid (761). Thursday, July 30th, is a 3ft SW swell, glassy, and good energy (452). Friday, July 31st, finishes the run with a 3ft SW swell, glassy, and moderate energy (259).
So, the plan is clear: hit the early mornings for the best conditions. The real standout is the 27th and 28th of July for the bigger, long-period SW groundswell with glassy wind. That’s the one you want to circle on the calendar.
Rusty, signing off.

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.
