The Island Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s on offer for The Island. We’ve got a solid 16-day window, but it’s a bit of a slow burner with a few absolute gems hidden in there.

Overall Pattern

The pattern starts modest, builds into a strong pulse of groundswell around the end of August, then has a messy, windy middle before a late run of cleaner, punchy surf in the first full week of September. The standout window is undoubtedly Friday afternoon the 28th of August through to Monday morning the 31st, and then again on the morning of the 8th of September. The rest of the time we’re fighting wind or dealing with lumpy conditions.

The Run Down

We kick off Wednesday the 26th morning with some clean 4ft SW groundswell (combined energy of 556), but it’s marginal. Not really worth paddling out for. The next morning, Thursday the 27th, we get a jump in energy with a 5ft SW swell, period 15 seconds, and combined energy hitting 1432. The wind is cross-shore though, so it’s lumpy. Not our day.

The First Standout

Friday the 28th is where it starts to get interesting. The morning is clean with a 6ft SW groundswell (energy 1617), but it’s the Friday afternoon session that’s the real gem. The wind goes glassy, dead calm, and we’ve got a beautiful 5ft SW groundswell with a 16-second period and combined energy of 1199. The water temperature is 59°, which is just about average for this time of year, so no worrying about a cold snap. The Island is a consistent reef break, and with that glassy surface it’s going to be clean, lined-up, and all-time for experienced surfers. This is your best call of the first week.

The Middle Ground

Saturday the 29th looks clean again with a gentle offshore wind and 4ft SW swell, but it’s smaller. Sunday the 30th morning sees the swell drop to 2ft but with a very long 19-second period and a clean offshore wind – that’s a fun, smaller window for the longboard or a proper reef-crawler. Monday the 31st morning brings a bigger 5ft SW swell (energy 1663) and cross-offshore wind, but it’s still a bit marginal. Then we hit a wall.

From Tuesday the 1st of September right through to Saturday the 5th of September, the wind is our enemy. Fresh cross-shore, cross-on, and onshore winds ruin the surface. The swell is there, hitting 6ft on the 5th, but it’s choppy and messy. This stretch is a write-off for a clean session. Kite surfers might love the wind and the 6ft swell, but for paddle surfing, it’s a hard pass.

The Second Standout

Sunday the 6th of September morning is a redemption story. The wind swings to a light cross-offshore breeze, and we’ve got a clean 5ft SW groundswell (energy 1067). This is excellent for experienced surfers. Monday the 7th stays clean with a bump in size to 6ft SW (energy 1345), but it’s still a bit marginal.

The Best of the Run

Then, Tuesday the 8th of September morning. This is it. The standout of the entire outlook. We’re looking at a 6ft SW groundswell with a long 18-second period, a moderate offshore wind, and a combined energy reading of 2260. That’s strong wave energy. The Island is a reef, so this long-period groundswell will wrap in perfectly, offering proper, powerful, hollow waves. It’s a bit overhead for the average punter, but for the experienced crew, this is the session to circle. The wind is clean and offshore, so it’s going to be a proper morning.

After that, Wednesday the 9th and Thursday the 10th of September see the wind turn nasty again, with fresh cross-shore winds and the swell getting too big at 8ft, making it a messy, expert-only affair at best, and largely unsurfable.

So, to keep it simple: Friday afternoon the 28th of August is your first standout call – glassy, clean, fun groundswell. Tuesday morning the 8th of September is the big one – bigger, punchier, and still clean. The rest of the window is either too small, too windy, or too messy. Get out there for those two windows.
