The Lowdown
Alright, Rusty here, let's talk about what's cooking at Green Island.
We've got a solid run of surf ahead, starting Sunday morning (August 2nd) with some real nice conditions. The water's sitting at 63°, which is pretty much what you'd expect for this time of year, so no surprises there.
Sunday morning kicks things off with a clean 5ft SE swell, a 12-second period, and a light cross-off breeze from the north. The energy's moderate at 745, and the waves are looking clean and well-shaped. This is a great call for the advanced crew, classic Green Island reef style. The swell direction matches what this spot loves, and the wind is going to keep it smooth. Crowds can show up here sometimes, so get in early if you can.
Sunday afternoon stays clean with a 5ft SE swell, still that 12-second period, and the wind holding cross-off. It's a good session, but the morning is the pick.
Monday morning (August 3rd) sees the swell drop to 3ft from the SE with a 10-second period and a clean offshore breeze from the NW. The energy is low at 137, so it's small but surfable. The wind is offshore, which is always a sweet bonus for this reef.
Tuesday through Wednesday is a bit of a write-off with tiny waves and poor conditions. Thursday morning (August 6th) though, things get interesting again. We get a 5ft S swell, 8-second period, and glassy conditions with zero wind. The energy is solid at 312. It's a beach break setup, and with that short period, it might be a bit straight, but the glassy water will make it fun. Friday morning (August 7th) is similar, another 5ft S swell and glassy conditions. The wind is dead calm, and the energy is 324. This is clean, clean surf.
Saturday morning (August 8th) offers a 4ft SSE swell with a 9-second period and a light cross-off breeze from the NE. The energy is 234, and it's clean. A solid option for a weekend paddle.
Then we hit a bit of a lull through Sunday and Monday (August 9th-10th) with small, ordinary waves and some stronger winds. Not worth rushing out for.
Now, listen up, because the real standout is coming. On Friday, August 14th, we get a big pulse. Friday morning shows a 10ft S swell, 10-second period, and glassy conditions. The energy is massive at 3296. This is for experienced surfers only - 10ft is too big for beginners. The wind is glassy, and the waves will be powerful. This is a serious session for the crew that knows what they're doing. Friday afternoon gets even bigger at 12ft from the SSE, with a 12-second period, but the wind swings onshore from the SE, which might mess with the shape a bit.
Saturday morning, August 15th, holds the size at 10ft from the SSE, a 12-second period, and a clean cross-off breeze from the west. The energy is still huge at 2953. Another excellent day for experts, with clean conditions.
Sunday morning, August 16th, the swell drops to a more manageable 6ft from the SSE, 11-second period, and glassy conditions. The energy is 875. This is a very good call, and the glassy wind will make it smooth. The long period (11 seconds) means it'll have some push, but it's not too crazy.
Monday morning, August 17th, finishes the run with a clean 3ft SSE swell, 10-second period, and a solid offshore breeze from the north. The energy is 229. A nice, clean, smaller day to wrap things up.
So, the best of the best? Without a doubt, the morning of Friday, August 14th, and the morning of Saturday, August 15th, are the big standouts. The combination of serious size, glassy or clean wind, and that massive wave energy is going to produce some memorable waves. Just be ready for the crowd and the power.
Rusty.

Information about the Green Island Surf forecast
The above surf forecast table for Green Island provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Green Island can be found by selecting the local surf guide option on the grey menu. Our Green Island 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 (Green Island) 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 Green Island 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.
