The Lowdown

Alright folks, Rusty here. Let's break down the next couple of weeks for our local zone. It's a slow start, but there's a real pulse of swell coming if you're willing to wait.

For the first week, starting on September 4th, it's a tough slog. The swell is sitting around 4 to 5ft from the SSW, but the wind is a stubborn cross-shore, mostly from the SE, blowing at 15 to 19 mph. That's putting a real chop on the surface, making it messy. The 'combined energy' is moderate, hitting 644 early on, but it's not translating into anything rideable. It's a classic case of "looks better on paper than it does in the water." The water is sitting at a warm 85°, which is about average for this time of year, so you won't need a thick suit, but you'll need a lot of patience. We're looking at this sloppy, cross-shore mess right through to the 11th. There's a slight lift on the 8th and 9th as the swell bumps up to 5 to 7ft and the 'combined energy' climbs into the 1600-2100 range, but the wind is still ruining it. It's a real grind.

Now, hold on to your board. The 12th of September is where things start to get interesting. The swell builds to 6ft from the SW with a long period of 19 seconds, and the energy jumps to 3273. That's a proper groundswell. The wind is still a light cross-shore, so it's not perfect, but the potential is there. This builds into a solid run. By the 13th, we're seeing 8ft SW swell, which is getting into the "experienced only" territory for most, with a 'combined energy' of 3450. The wind is still light, but it's a powerful, long-period swell.

The standout window is the 14th and 15th of September. Look at the 14th. Monday morning, the wind is dead calm, glassy. The swell is a solid 7ft from the SW, with a period of 15 seconds and a 'combined energy' of 2109. Afternoon holds it with a 7ft SW swell and glassy conditions. This is as good as it gets. We're talking clean, powerful groundswell. This is the one to circle on the calendar. The 15th morning is also excellent with a light offshore, 6ft SW swell.

Then we get another shot on the 18th of September. Friday morning, the 18th, is glassy again with a 7ft SSW swell, a period of 17 seconds, and a 'combined energy' of 2489. Another proper window of clean, powerful surf for the experienced crowd.

Let's be honest, Gilligans is the only game in town, and it's a reef break that's very consistent. It's exposed to the SW swell, which lines up perfectly with what's coming. The standout, without a doubt, is the 14th of September. That Monday morning with glassy conditions and a 7ft SW groundswell... that's the one you call in sick for. The 18th is a close second. The other days, even when the swell is up, the wind is a factor. The 12th and 13th have the size but the cross-chop will make it a battle. The 14th and 18th are the clean gems.

Stay sharp, and pick your windows.

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.
