Flatrock Surf Forecast and Surf Report

Alright, Rusty here. Let's take a long, hard look at what Flatrock has in store for us over the next couple of weeks. We've got one spot to focus on, so let's get into it.

First things first, Flatrock is an advanced reef break, exposed to the SW. It's a spot that needs the right key to unlock it. Right now, the water's sitting at 59°, which is pretty much exactly what you'd expect for this time of year—nothing weird going on there.

We're starting off a bit slow. The first real wave of action hits us on Thursday the 27th of August in the afternoon, but honestly, it's a bit of a washout with a cross-on wind and a 5 ft SW swell. The energy is there (3038), but the quality isn't. We'll be waiting for cleaner conditions.

The first genuine standout comes on Friday morning, the 28th of August. The swell bumps up to a solid 8 ft from the SW, with a 16-second period packing some real grunt. The combined energy is massive at 3313. What makes this special is the light NE cross-off wind. It's going to be clean, punchy, and powerful. This is for experienced surfers only—it's too big for beginners. The swell direction is a perfect match for this break. This morning session is your best bet of the entire run.

Saturday the 29th keeps the good vibes going with the morning session. A 5 ft SW swell and a clean offshore wind from the East. The energy drops a bit (1054), but the shape should be fun. Sunday the 30th has a weird one: a 3 ft SSW groundswell with a 20-second period. That's a very long period, so the sets will be fat and walled up, with long lulls. It's a decent wave but it might be a bit straight for Flatrock. Still, the gentle offshore wind makes it worth a look.

The next date to circle is Monday the 31st of August in the morning. We're looking at an 8 ft SW swell with an 18-second period and an incredible 7767 combined energy. The wind is a light cross-off from the NNE. It's going to be big, powerful, and absolutely pumping. This is another session for experienced surfers only. The potential is huge, but the tide and shape can be tricky at this size and period.

Then the wheels fall off. From Tuesday the 1st of September right through to Tuesday the 8th of September, it’s a write-off. We're looking at a solid week of strong onshore or cross-shore winds, ranging from moderate to near-gale force. The swell stays big, over 8 ft at times, but the wind will destroy any chance of a clean wave. For kite surfers, the 31 mph NW wind on the 6th might look interesting, but for a paddle surfer, it's a no-go.

We get a second wind, fingers crossed, around Wednesday the 9th of September. The morning shows a 6 ft SW groundswell with clean offshore easterly winds. The energy is solid at 1897. The afternoon is even better, with a 7 ft SW swell and a score of 5 for the conditions, still clean with a gentle cross-off breeze and energy at 3227. This is a solid, clean option to close out the second week.

The final days, the 10th and 11th of September, look marginal with cross or cross-on winds. The swell is still there, but the quality drops off again.

So, to sum it up: if you're an experienced surfer, your two standouts are the Friday morning, August 28th, and the Monday morning, August 31st. Both are big, powerful SW groundswells with clean wind. They're the only true must-surf windows in this 16-day stretch. The rest is a mix of small windows and a whole lot of blown-out junk.

Stay salty.
Rusty.
