The Lowdown

Alright, let’s get into it. The forecast is pointing to one spot that’s got the goods again and again, so I’ll be keeping my eyes locked on it.

The next two weeks are all about one break: Gilligans. It’s a reef setup, very consistent, and it’s exposed to the southwest swell. The water temp is sitting at 86° – that’s about 1° warmer than average for this time of year, so nothing too wild, just a touch of tropical warmth.

We kick off on Wednesday, July 15th, with a solid morning session. Swell is 6 ft from the SSW, with a long 15-second period (groundswell), and the combined energy is pumping at 1404 – that’s strong wave energy. Wind is a light cross-off from the ESE at 6 mph, so the surf is clean. This is excellent for experienced surfers, but with that size and power, it’s not one for beginners. Crowds are possible here, so get in early.

The standout of the whole forecast though – and I mean the real gem – is Monday, July 20th, in the morning. Swell bumps up to 6 ft from the SSW, period is a very long 17 seconds, and the combined energy hits 2057 – that’s strong to very strong. Plus, the wind is glassy from the east at just 3 mph. That’s as good as it gets. Clean, powerful, long-period groundswell lines reeling down that reef. This is where you want to be.

After that, the size drops a bit but stays fun. On Sunday, July 19th, the afternoon shows a glassy 3 ft swell from the SSW with a super long 18-second period, but it’s small. Still, with glassy conditions, that’s a sneaky good session for a longboard or a log.

Through the rest of the week, we see a mix of clean and choppy conditions. Saturday, July 25th, is worth a mention – morning has offshore NE wind at 6 mph on a 2 ft SSW swell, and the afternoon goes glassy with a 3 ft SSW swell. Clean and small, but clean.

From the 22nd through to the 27th, it’s mostly cross-shore winds and smaller swell, with energy dropping into the hundreds (moderate to weak). The surf is there, but it’s not going to be special. The end of the month, around July 30th, shows a pulse of energy coming back – 4 ft to 4 ft from the SW with a very long 19-second period, and combined energy in the 1500s, but the wind is cross-shore, so it’s not going to be as clean as those earlier days.

If you’re an experienced surfer, the clear winner is the morning of Monday, July 20th. That’s the one. The rest of the run is a steady mix of good-to-okay. Keep your wetsuit handy.

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.
