The Lowdown

Alright, this is Rusty, and I’ve got the straight-up word on the surf for this spot for the next couple of weeks.

Right off the bat, the opening days are a bit of a letdown, I gotta be honest. The swell is there, but the wind is just cross all day and the conditions are choppy. It’s not a total flat spell, just a frustrating one. We’re looking at a solid run of swell from the 7th of September through the 11th, but the quality is poor. It’s not until Saturday morning the 12th that things start to come together. The water temp is sitting at 85°, which is pretty much what you’d expect for this time of year.

So, let’s talk about the real gem in this whole forecast. The standout is Saturday the 12th, early morning at Gilligans. We’ve got a clean 6 ft of south-west groundswell rolling in, with a proper long period of 19 seconds – that’s a lot of energy in the water (combined swell energy of 2940). The wind is an off-shore/cross-off light breeze, meaning it’s going to be clean, and the report even says excellent conditions for experienced surfers. For this reef break, a south-west swell is spot on. It’s a very consistent break, and with a solid long-period groundswell like that, paddling out between sets will be manageable.

Now, that long period is a double-edged sword. It’s got heaps of power and shape, but at a beach break, it can make waves close out a bit too straight. Since Gilligans is a reef, this swell will handle beautifully. Crowds are listed as “sometimes,” so you can expect a few other keen surfers there for sure.

Looking further out, we’ve got another window that looks promising but less certain. The weekend of the 19th of September is something to watch. The morning of Saturday the 19th has a 6 ft south-west swell with near-calm offshore winds, and the afternoon is a full-blown glass-off – 7 ft of south-west swell with a 15-second period, glassy wind, and the water will be like a mirror. That is an absolute dream scenario for an evening session. The energy is solid at 1764. Then the 17th of September morning also shows some clean lines with a light offshore, but the swell is a touch smaller.

A word of caution: once we get into the second week, around the 20th, the swell jumps up to 8 ft and the wind turns cross-onshore and choppy. That’s a proper shralping, maybe one for the experts, but the quality drops off hard. Anything over 8 ft here with onshore wind is going to be a mess.

So, in short: the first week is a washout from the 7th to the 11th. Your absolute best bet is Saturday the 12th morning. After that, keep an eye on the 17th, and then the 19th afternoon looks like the real magic window if the forecast holds.

Stay stoked.

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.
