The Lowdown

Alright, let’s see what’s cooking. The Tree is the only game in town for the next 16 days. It’s a slow start, but the second week is a proper corker. The first few days are small and clean, then we get a dose of long-period groundswell that’ll have the reef working nicely. The standout is definitely the second Thursday and Friday.

We start on Friday, July 31st, with a clean 3ft SW swell, period 14 seconds. Glassy conditions with a light northerly breeze. The combined energy is moderate (296). It’s a nice little session. Saturday, August 1st, and Sunday, August 2nd, are similar, with the swell dropping to 2ft and 2ft. Sunday morning has a clean, cross-off breeze, but it’s small. The Tree is an exposed spot, so it’s picking up everything, but at this size, it’s a gentle paddle for the advanced crew.

Monday, August 3rd, and Tuesday, August 4th, keep the same story: small, clean mornings with glassy conditions. The swell hangs around 2ft to 3ft, still with that nice SW direction. The combined energy is moderate, in the 200s. By Wednesday, August 5th, and Thursday, August 6th, the period drops to 8 seconds – that’s short-period wind swell, and the energy drops to 129 and 139. It’s surfable, but pretty ordinary. The mornings are glassy, but the waves won’t have much push.

Now for the good stuff. Friday, August 7th, we see a jump in period to 18 seconds – that’s a very long period groundswell. The swell is only 2ft, but the energy jumps to 361 (moderate). The morning is clean with a cross-off breeze. The Tree is a reef setup, and that long period will make it really stand up and offer some nice, lined-up walls. It’s for the advanced surfer.

Saturday, August 8th, and Sunday, August 9th, keep that long period, around 16 to 14 seconds, with the swell building to 3ft and 3ft. The energy is getting strong, hitting 498 and 384. The mornings are glassy. This is the pick of the first week. The crowds are a possibility at The Tree, so get out early.

Monday, August 10th, is a cracker, with a flat calm morning and 2ft of glassy SW swell. The energy is moderate (239). Tuesday, August 11th, is also clean with a cross-off breeze. But the real standout is the stretch from Wednesday, August 12th, through Saturday, August 15th.

On Wednesday, August 12th, the period jumps to 19 seconds with a 2ft swell. The energy is 397. Thursday, August 13th, is the absolute pinnacle. The swell is 3ft from the SW, period 16 seconds, and the energy is a massive 660 – that’s strong to very strong wave energy. The morning is dead calm, glassy as a mirror. Expect very long, clean lines peeling down the reef. This is the best session on offer. Friday, August 14th, and Saturday, August 15th, are not far behind, with energy in the 500s and 600s, and glassy mornings. This is a long-range standout, so it’s a promising outlook, but keep an eye on the forecasts as we get closer. The water is about average for this time of year.

So, to sum it up: the first few days are small but clean. The real magic is from August 7th onwards, especially the 13th, 14th, and 15th. That’s where you want to be. The Tree is an advanced wave, and with that long period groundswell, it’s going to be a proper reef-break session. Don’t sleep on it.

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.
