The Lowdown
Alright folks, Rusty here. Let's talk about the surf at The Tree over the next couple of weeks. This is an advanced, exposed reef-point that lights up on a solid SW groundswell, and the water is sitting at 86.4°F, which is a good 3.2°F warmer than the long-term average for this time of year, so it's a touch toastier than usual.
The first few days are a bit of a mixed bag. Sunday the 19th afternoon sneaks in a 3.3ft S swell at 12 seconds, but with onshore SW wind and only marginal conditions, it's not worth the paddle. Monday the 20th morning though, things start to get interesting – a glassy 2.3ft SW groundswell with a 16-second period, and the wind is almost dead calm. That's a clean, long-period pulse that should peel nicely, even if it's small. The afternoon holds similar glassy conditions with a touch more energy (combined energy 549). Tuesday the 21st morning stays glassy with a 2.6ft SW groundswell at 15 seconds – still

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.
