The Lowdown
Alright, surf is finally looking up around here. It’s been a bit quiet, but we’ve got a solid run of waves coming our way over the next couple of weeks, especially if you can get out in the mornings. The glassy conditions are going to be your best friend.
The first few days are pretty small, with knee to waist-high lines, but there's some good energy in the water. The standout for me is Thursday the 10th. The swell is building to about 4ft from the southwest, with a solid 17-second period. The combined energy is pushing up to 921, which is strong, and with the wind completely glassy, it's going to be clean and lined up. That’s your pick of the first week.
Then we ease off a bit into the weekend. Saturday the 12th and Sunday the 13th still have some waist-high leftovers, but the energy drops off and the short-period swell (13-14 seconds) won't have the same push. It’s still worth a paddle if you’ve got the itch, but Thursday is the day.
The middle of the week, Monday the 15th, sees the wind pick up out of the southeast and things get a little messy. The surf gets chopped up and the quality drops. It’s not looking like fun for a paddle board. Honestly, that setup with the onshore breeze might be better for kitesurfing.
We have a bit of a lull from Monday the 15th through to the weekend, with small, inconsistent waves and wind issues. But there’s a promising sign for Sunday the 20th – we get a clean 2-3ft from the southwest with a 19-second period. The period is long enough to get things organized, especially if the wind holds off. It's a better option than the previous few days but still small.
Looking further out, Tuesday the 22nd is another standout. The forecast has 2-3ft from the southwest with a 16-second period and very clean conditions early on. It's a bit further away, so we'll have to see how it develops, but it's looking like a good bet for a morning session. The energy is moderate and the wind looks right.
Overall, the swell direction is solid from the southwest, which is spot on for The Tree. There’s no shortage of waves, just focus on the cleaner morning windows. Thursday the 10th is the main event, with Tuesday the 22nd shaping up as the long-range promise.

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.
