The Lowdown

Hey, Rusty here. Let's get into what The Tree has in store over the next couple of weeks. Water temp is sitting at a balmy 86°, a touch warmer than usual for this time of year, which is a nice little extra.

The start is pretty average. Saturday the 18th is a dud – a weak 3ft SSW swell at 12 seconds is getting ripped up by a cross-onshore wind. Not worth a look.

We finally get some clean surf on Sunday morning the 19th. Wind swings light cross-off from the NNW, and we’ve got a 3ft S swell with a 14-second period. Combined energy is solid at 452 (moderate). Clean conditions, but it’s small. Not a standout, but it’s a start.

Monday afternoon the 20th is where it starts to get interesting. A 3ft SW groundswell rolls in at a long 16 seconds. The wind drops to glassy – just a slight air from the WSW. Combined energy hits 589 (moderate). The combo of long-period groundswell and glassy conditions will create some really clean, well-shaped waves. This is the first real standout. It’s small, but for an advanced spot like The Tree, the quality will be there.

We get a few more clean mornings – Tuesday the 21st holds a clean 3ft SW swell, Wednesday the 22nd is glassy with 2ft SW at 13 seconds – but the energy drops into the mid-200s. Surfable, but nothing special.

Friday morning the 24th brings a very long period 24-second SW groundswell at 2ft. Combined energy jumps to 711 (strong). That’s serious groundswell energy for a small height. It’s clean with a light cross-off breeze. Saturday morning the 25th keeps the momentum with a 3ft SW at 21 seconds and 672 energy (strong). Still clean.

Sunday morning the 26th is glassy flat calm with a 3ft SW at 19 seconds and 843 combined energy (strong). That’s a beautiful setup. Clean, glassy, decent size, and long-period groundswell.

But the real standout of the whole forecast? Monday morning the 27th. We get 4ft of SW swell at a long 19 seconds, combined energy of 1375 (very strong), and cross-offshore winds from the NNW. Conditions are clean and the wave comment says it’s excellent for experienced surfers. That’s the one. Tuesday the 28th is very similar – 5ft SW at 17 seconds with 1264 energy, also clean in the morning.

From there, the swell hangs around 4 to 4ft through the end of the month and into early August. Wednesday the 29th and Thursday the 30th mornings are glassy with solid energy (884 and 652). After that, it tapers off. The first few days of August see a drop, with small glassy 2ft days on the 1st and 2nd. Worth a paddle if you’re keen, but not the main event.

So, to sum it up: the best bets are Monday morning the 27th and Tuesday morning the 28th of July. Big energy, clean conditions, proper groundswell. If you can only get out once, make it one of those.

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.
