The Lowdown
Alright folks, Rusty here. Let’s get into it for this stretch. We’ve got one spot on the radar, and it’s The Tree. This is a reef setup, exposed to the SW, so it needs a good solid south-west groundswell to light up. It’s rated for advanced surfers only, and it’s fairly consistent. Expect crowds sometimes.
The water temp is sitting at a touch warmer than normal for this time of year, about 87°F, which is a notable 3°F above the long-term average. The water feels like bathwater.
We start off Monday the 13th with a clean 3ft SSW swell, period at 13 seconds, and the wind is glassy. The combined energy is moderate (446). It’s a proper little morning glass-off. The afternoon sees a cross-on breeze kicking up, so the morning is the go.
Tuesday the 14th pushes up to 3ft with a 14-second period. The morning wind is cross-off and clean, making for some nice, lined-up waves. The energy is still moderate (418). Wednesday the 15th is similar, 3ft, glassy again first thing, with 430 in energy. This pattern holds through Thursday the 16th and Friday the 17th, with morning glass-offs and small, clean 3ft to 3ft SSW swell. Friday afternoon actually looks glassy too, with a spike in energy to 466. Saturday the 18th is another morning glass-off with 3ft.
Now, here’s the standout. Sunday the 19th is the pick of the first week. The morning brings a 3ft swell from the S, but the period is 14 seconds and the combined energy jumps to 610 (moderate to strong). The wind is glassy. This is a very good session on the cards. Monday the 20th is also very good in the morning, with 3ft SSW swell, 13 seconds, and 556 energy. The swell direction is a near-perfect match for the break.
The second week sees the swell dip a bit. Tuesday the 21st and Wednesday the 22nd are still clean in the mornings with 3ft and 2ft. There’s a definite drop in energy by the 22nd (237). Thursday the 23rd is very small, only 1ft.
Then, on Friday the 24th of July, we get a short-period spike. It’s 5ft from the SSW but only 7 seconds. The morning is glassy again, but with that short period, it’s going to be a bit mushy and bumpy. The energy is moderate (301). The afternoon is a write-off with strong onshore wind.
The real long-range gem is Sunday the 27th of July. The morning has 3ft from the SW with a 18-second period and a very strong energy reading of 557. The wind is glassy. And then Monday the 28th of July is even better: 3ft from the SW at 16 seconds with a huge 570 energy, and the wind is flat calm. That’s a very long period, proper groundswell, so it will wrap in nicely at The Tree. These are promising but less certain this far out, so keep an eye on it.
Overall, the morning windows are the only game in town. The wind is almost always better first thing. The 19th and 20th of July are the real standouts in the near term, with the 27th and 28th looking like the potential bombs for the experts.
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.
