The Lowdown
Alright, Rusty here. Let’s have a look at what’s cooking.
We’ve got a solid run of surf coming up at The Tree, an advanced spot that’s fairly consistent and exposed to the southwest. The water’s sitting at a warm 86° which is a touch warmer than normal for this time of year – feels like a bath out there. It’s a point break setup, so those long period swells we’re seeing later will be right at home.
The action kicks off Friday morning, 17th July. Small but clean, with a 3ft SSW swell at 12 seconds and a light cross-off breeze. The combined energy is moderate at 376. It’s not huge, but it’s rideable and the wind keeps it tidy. Saturday morning, 18th July, drops slightly to 2ft but the wind goes glassy – dead calm – and the period stretches to 14 seconds. That’s a long-period groundswell, real clean, and with a combined energy of 392, it’ll have some push. Good for a patient surfer.
Sunday morning, 19th July, is more of the same: 3ft, glassy, 14-second period, combined energy 440. The swell is consistent. But the real standout comes Monday, 20th July. The swell drops to 2ft but the period jumps to 16 seconds – that’s a very long period groundswell. Both the morning and afternoon are glassy with zero wind. Combined energy hits 514 to 549. For a point break, this is primo. Clean, lined-up, and the long gaps between sets make paddling out easier. It’s not big, but the quality is top-notch. This is the best on offer in the first week.
Tuesday through Thursday morning, 21st to 23rd July, stay clean and consistent with swell in the 2ft to 4ft range. The wind is light and offshore or cross-off, keeping the surface smooth. The 23rd afternoon sees a short-period 8-second swell at 4ft, so it’ll be a bit weaker and messier, but still rideable.
Now, Friday 24th July morning is a real gem. The swell is only 2ft but the period is a massive 24 seconds – that’s an incredibly long, powerful groundswell. Combined energy is 611. With a light cross-off, it’s going to be peeling down the point. This is another standout. The afternoon goes glassy, too.
The second week gets a bit more interesting. Saturday 25th July has a risk of storms and a moderate cross-off wind, but the swell remains long-period at 21 seconds, with combined energy of 678 in the afternoon. Sunday 26th July morning is clean with a 3ft, 19-second swell, energy 856. Then Monday 27th July morning is the big one: 4ft, 17-second swell, glassy, with combined energy of 1157. That’s strong wave energy. For an advanced break, this is excellent – clean, powerful, and well-shaped. The afternoon goes a bit cross-on, so the morning is your window.
The rest of the week into early August holds steady. Swell stays in the 3ft to 4ft range with long periods, and the wind is often glassy or light. There’s a lot of good surf here, but the absolute standouts are Monday 20th July, Friday 24th July morning, and Monday 27th July morning. The Tree will be handling those long-period swells beautifully.
Crowds are possible here, so get in early on those glassy mornings.
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.
