The Lowdown

Alright, let's get into it. The Tree is a bit of a mixed bag over the next couple of weeks. The water’s sitting at a warm 86.2°, which is a touch warmer than normal – feels like a bath, honestly.

Monday the 14th starts small and clean. We’ve got a knee-high southwest swell at a super long 19-second period. The energy is weak – only 269 – but the morning is glassy. If you're keen, it's a slow, clean one for the logs. The afternoon gets a bit crossed, so make the most of the morning.

Tuesday the 15th is more of the same, but the energy picks up to 410 with a bit more size – still around thigh-high. The morning is dead glass off. The afternoon gets a bit messy, so stick to the early session.

Now, Wednesday the 16th is where things get a little more interesting. The swell gets up to the 3ft range and the morning is glassy. The combined energy is 512, so there’s a bit more push. It’s a fun, clean, waist-high day. The period is still a healthy 16 seconds. This is probably the pick of the first week for a clean, cruisy session.

Thursday the 17th is similar in size, but the period drops a touch. Morning is glassy again with a 14-second swell. The afternoon turns onshore, so it’s a morning mission.

Friday the 18th backs off – back down to 1.5ft to 2ft. The morning is glassy with a 20-second swell, but it’s pretty gutless. The energy’s down to 335. It’s a dribbler.

Saturday the 19th is small again, 1.5ft, with a 19-second period. Morning is glass, then the afternoon storms roll in and it’s onshore mush.

Sunday the 20th sees a slight bump back to 2.5ft, but the wind goes cross-shore. The morning is clean enough with a 19-second period, and the energy climbs to 575. It’s rideable but not great.

Monday the 21st is similar – 2.5ft to 3ft, 18-second period, and a cross-shore breeze. The energy is up a bit to 620 in the morning, but it’s not glassy. It’s workable.

Tuesday the 22nd stays around 2.5ft, but the period starts to shorten down to 16 seconds. The morning is cross-off and clean. The energy is still respectable at 613. Another early call.

Wednesday the 23rd is back to small – 2.5ft but the energy drops to 341. The morning is glassy, but it’s soft. The afternoon turns onshore and it’s poor.

Thursday the 24th is struggle town. 2.5ft, period down to 14 seconds, and the wind’s all over the place. The energy is in the low 300s. Not worth much.

Friday the 25th is similar – small, 2.5ft, 13-second period, but the morning is a cross-off which gets it a bit cleaner. Still, there's heavy rain around and it's marginal.

Now, hold tight, because Saturday the 26th is where things change. The swell jumps right up to 8ft but it's a short-period 9-second west-southwest swell. The combined energy explodes to 1250 – that’s proper power. But it's cross-onshore in the morning, choppy, and messy. The period is way too short for that size to be any fun – it'll be closing out and pitching hard. This is big, but it's not good. In the afternoon it backs down to 5.5ft, still short period, still onshore. This is a “watch from the beach” day.

Sunday the 27th is a different

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.
