Table - best surf conditions forecast for Gilligans over the next 16 days.
Alright folks, Rusty here. Let's have a proper look at what's on the cards for the next couple of weeks at Gilligans.
Gilligans is a very consistent, exposed reef break that loves a SW swell, and we've got a run of solid, long-period groundswell heading our way. The water temp is sittin' at 86°, which is about average for this time of year, so no surprises there. Wednesday afternoon (July 8th) kicks things off with a bang – a solid 6 ft SSW swell (combined energy of 1663 – that's strong) and glassy, calm winds. That's clean, powerful surf. This size is for experienced surfers only, not for beginners. Things get a bit average on Thursday and Friday though, with cross-shore winds and a bit of chop mucking up those 6 ft waves.
We see things clean up again on Saturday morning (July 11th) with a 5 ft SW swell, clean winds and lighter conditions. The real standout window is coming up, though. You want the best of the best? Mark your calendar for Monday morning, July 20th, and Tuesday the 21st. Monday morning has a big 6 ft SSW swell (combined energy of 2338 – very strong), glassy winds and that classic reef power. Tuesday morning is just as good, with a 6 ft SSW swell (1753 energy) and again, dead calm, glassy conditions. This is big, groundswell energy – the period is long (15-18 seconds) which means these waves will have serious punch and shape, but at a reef like Gilligans, that's exactly what you want. Crowds are possible here, so get in early.
There's a stretch of middling, cross-shore stuff after that, but don't sleep on Wednesday afternoon July 22nd either – a 5 ft S swell, glassy, and clean again. Even into Thursday July 23rd, there's 5 ft S swell with glassy conditions. Overall, the first week is a mix of good and average, but that second week holds some absolute gems. The long-range stuff on the 20th and 21st looks promising, but it's still a way out, so keep an eye on it.
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.
