Flatrock Surf Forecast and Surf Report

Alright, let’s take a look at what we’ve got coming up for Flatrock. We’ve got a really tidy, promising start to the weekend with clean conditions, but then the wheels fall off for a long stretch. Hold on, ’cause it’s a bumpy ride before things might settle again way down the track.

The first real standout is Saturday morning the 29th. Flatrock is showing a solid 5ft SW swell with a nice 14-second period behind it. That’s some proper groundswell energy, and with an easterly offshore breeze holding at 9 mph, it’ll be glassy and clean. The combined swell energy is moderate at 972, but the quality is what counts here – it’s going to be a good session for the advanced crew. That afternoon it drops a bit to 5ft, still clean, but the tide might get a little funky.

Sunday morning the 30th keeps the fun going. 5ft from the SSW, period down a touch to 13 seconds, but the combined energy jumps up to 1401 – you’ll feel that. Still offshore from the east, so expect clean, well-shaped waves. This is about as good as it gets for the first few days. Perfect for experienced surfers.

Now, Monday the 31st is the real highlight of this whole window. Morning session brings a 8ft SW swell with a super long 18-second period – that’s proper energy, and the combined swell energy is a ripping 7457. Offshore northeast breeze around 9 mph, so the reef will be holding shape beautifully. This is one for the experts only – 8ft is big, and that long period will make it even more powerful. If you’re confident, get out there early.

After Monday, things turn ugly. Tuesday the 1st into Wednesday and Thursday, we get hammered by onshore winds and lumpy, messy conditions. It stays poor through the whole first week of September. Even when the swell stays big – 8ft to 10ft – it’s blown out, with strong cross-onshore winds. Not worth paddling out. A few days are just total write-offs.

The second week doesn’t offer much relief. The wind stays strong or cross-onshore through to about the 7th, when the swell gets immense – up to 16ft and 18ft – but it’s just too big for Flatrock, with near gale winds. Not a paddle session.

Things may start to come back around Tuesday the 8th and Wednesday the 9th. Swell drops to 13ft Tuesday afternoon with clean SSE cross-offshore 9 mph winds – combined energy still massive at 12077. That’s only for the brave or the experienced, given how big it is. The pulse is still there on Wednesday morning, 12ft with a cross-shore and a bit of chop.

Thursday the 10th morning stands out as the last real possibility: 10ft SW swell, 15-second period, clean with a cross-off northerly breeze at 9 mph. Excellent conditions again for those who can handle it. After that, it’s back to onshore junk and lumpy seas, right through to the 13th.

So, in short: Saturday 29th to Monday 31st is your window. Monday morning the 31st is the pick of the whole outlook – that 8ft with 18 seconds and offshore wind is going to be magic at this reef. The gap after that is huge – basically from Tuesday through to the following Thursday, the 10th, there’s very little worth chasing, and that Thursday is only for the big-wave chargers. Get it while you can.

Water temp at Flatrock is sitting at 59°, which is bang on average for the time of year – no need for a thick suit, but a 3/2 will do you fine.
