The Lowdown
Alright folks, Rusty here. Let’s get into it.
Right from the start, we’ve got a solid run of swell lining up, but it’s a bit of a mixed bag with the wind. The first real standout is Wednesday the 26th morning at Gilligans. You’ll be greeted by a clean 5ft SSW groundswell with a 13-second period, and the wind is glassy out of the ESE at 3 mph. The water is sitting at 85°, which is about average for this time of year. The combined energy is moderate at 834. It’s real nice, but it’s a short window – that afternoon the wind swings cross-shore and the quality drops.
Thursday the 27th through to the end of August sees a solid pulse of SSW swell, but the wind stays cross-shore, so the surf is a bit crumbly. The standout energy peaks on Thursday afternoon with a 7ft SSW swell packing 18 seconds and a combined energy of 2848, but the cross-shore breeze keeps it from being perfect. That size is also getting into the “too big for beginners” zone. As we head into the first week of September, the swell hangs in there, but the wind stays cross or cross-onshore. The consistency is very consistent, so there’s always something to ride, but the quality is marginal.
The next real highlight comes on Tuesday the 8th of September morning. The wind goes glassy again, out of the ENE at 3 mph, and we’ve got a 4ft SSE swell, but the period is short at 8 seconds. The combined energy is weak at 514. It’s clean, but don’t expect much punch. The afternoon glass-off returns with a 2ft S swell at 17 seconds – that’s a long-period groundswell, but it’s small. The combined energy is 728, still weak.
Then, Wednesday the 9th of September morning is the one to circle. Clean conditions with an ESE cross-offshore breeze at 3 mph, and a 5ft SSW swell at 17 seconds. The combined energy is 1637 – moderate. This is excellent for experienced surfers. The wind is perfect, the swell is solid, and the direction is right on the money for Gilligans. That’s our best bet in the whole outlook.
After that, the swell backs off a touch and the wind turns cross-shore again through the second week. It’s rideable, but nothing to write home about.
So, if you’ve got a board, make the most of Wednesday the 9th of September morning at Gilligans. That’s the one.
Rusty.

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