Flatrock Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what Flatrock has cooking for us over the next couple of weeks. This is a solid, exposed reef break, and the models are showing a run of decent SW groundswell, so we’re not staring at a flat spell. The water temp is sitting at 59°, which is pretty much bang on average for this time of year – no surprises there.

The first few days are a bit of a mixed bag. Saturday the 22nd and Sunday the 23rd have a solid 8ft SW swell rolling in, with a super long 15-16 second period – that’s proper groundswell energy. The combined energy is strong, hitting over 3300 and then 3700. But the wind is messy. Saturday morning is a cross-on with 9 mph from the SW, which is going to leave things a bit choppy. Sunday morning cleans up nicely with a cross-off breeze from the NNE, but the wind picks up to 12 mph. It’s not trash, but it’s not the pick of the window either. The wave comment even says “marginal,” so don’t expect perfection.

Monday the 24th sees the swell drop to 5ft, still a fine 14 second period. The wind switches offshore from the East at 19 mph, which is strong but clean. The energy drops to 1062, so it’ll be weaker, but that offshore wind will make for some clean lines if you’re after a more relaxed session.

The big news starts brewing toward the end of August and into September. Tuesday the 27th of August has a 10ft SW swell with a 19 second period – that’s a very long period groundswell. Combined energy is pumping at 7275. The wind is light and cross-shore from the North at 6 mph. This is a standout morning for experienced surfers. That long period will wrap beautifully around the reef, but be aware that with a period that long, it can get a bit straight at times on a reef. Still, this is a quality window.

Then we get to the true standout. The 5th and 6th of September. Mate, this is the one to circle. Saturday the 5th has a massive 13ft SW swell with a 17-second period, and the combined energy is off the charts at 8826. The wind is offshore – ENE at 12 mph and then light Easterly. The wave comment calls it “exceptional for expert surfers,” and I’m not gonna argue. This is big, powerful, and clean. This is not for beginners – 13ft is expert only. Sunday the 6th stays big at 13ft, but the wind gets a bit more cross-off from the NNE and fresh at 22 mph in the morning, which could make it a bit tricky.

If you’re picking one day, Saturday the 5th of September at Flatrock is the best on offer. Huge swell, clean offshore wind, and massive energy. It doesn’t get much better for the advanced crew.

There will be a bit of a lull in quality around the 2nd, 3rd, and 4th of September where the wind gets messy and the swell drops, but don’t let that put you off – the big stuff is waiting. Crowds are listed as “sometimes,” so you might have company at a spot this good, but on a 13ft day, it’ll thin out.

Right, I’m signing off. Rusty.
