The Lowdown

Alright, let’s get into it. Gilligans is going to be the place to be over the next couple of weeks. The water’s sitting pretty at 85°, running just a touch warmer than usual for this time of year. We’ve got a long-period SSW groundswell lining up, and for a reef like this, that’s a beautiful thing. The energy in the water is strong, too, with readings in the thousands.

We start things off on Wednesday the 5th. The morning’s got a solid 6ft of SSW swell with a 15-second period, and a light NE offshore breeze keeping it clean. The energy is pushing 2200. That afternoon, the swell eases a bit to 4ft, but the period stretches way out to 19 seconds and the wind goes glassy. That’s a magic window – long, clean, and smooth.

Thursday the 6th, the swell builds to 7ft with a 16-second period, but the wind swings NW and gets a bit cross. The morning is still okay, but the afternoon gets a bit of chop. It’s still surfable, just not as pretty.

Friday the 7th is where it gets real. Swell up to 8ft in the morning, 8ft in the afternoon, with a 17-second period. The wind is cross-off from the NNW, and the afternoon is looking excellent – clean, powerful, and the energy jumps to 3841. That’s a standout session, no doubt.

Saturday the 8th keeps the quality high. Still around 8ft in the morning, easing to 8ft in the afternoon, with a 16-second period. Light ENE wind in the morning, then a light ESE cross-off in the afternoon. Energy is still well up around 3000. Another day of proper, grinding reef waves.

Sunday the 9th is a bit of a washout. The wind swings SE and picks up to 20 km/h, putting a real cross-shore chop on the surface. Swell is still 7ft, but the quality drops right off. Monday the 10th sees more of the same cross-shore wind, though the morning period jumps to 21 seconds, which is nice to think about, but the surface is going to be lumpy.

Tuesday the 11th brings more cross-shore wind, but the swell is up to 8ft and the energy hits a strong 5065. It’s a grind, but there’s plenty of power out there. Wednesday and Thursday the 12th and 13th are similar – decent size, but the wind just isn’t your friend.

Friday the 14th and Saturday the 15th see the wind go more south, cross-on, with the swell holding around 8ft. It’s going to be a bit lumpy and less appealing.

Then, on Sunday the 16th, it cleans right back up. The wind drops to glassy in the morning with a 7ft SSW swell, and the afternoon goes cross-off with a slight air. The energy is lower, around 2000 and 1576, but the conditions will be perfect. That’s another standout for the cleaner, more manageable waves.

The following week, starting Monday the 17th, we see a bit of a lull in quality, but then the big one looms. Tuesday the 18th sees the swell build big time, reaching 12ft in the afternoon with a 19-second period and the energy cranking to 7798. That is serious, expert-only territory. The wind is cross-shore, which will make it a bit of a mess, but the raw power is undeniable. Wednesday the 19th keeps it big at 10ft, then it starts to ease off into Thursday the 20th.

So, the best bets are looking like Friday the 7th afternoon and Sunday the 16th morning for clean, quality waves. The 18th is for the brave only – that’s a solid step up in size and power. Keep an eye on the wind, it’s the main player here.

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.
