Flatrock Surf Forecast and Surf Report

Right then, let’s have a look at what’s on the table for Flatrock over the next couple of weeks.

We’ve got a classic reef setup here that really wants a clean SW groundswell to show its best side. The good news is we’re seeing some serious energy coming in at times, with combined swell energy readings pushing up into the thousands (7857) – that’s proper power. The water’s sitting at 59°, which is exactly average for this time of year, so nothing weird there.

Now, the first few days are a write-off. Tuesday the 25th and Wednesday the 26th are messy – cross and cross-onshore winds blowing in the mid-teens to 35 km/h, turning a solid 10 ft SW swell into a lumpy, choppy mess. Not worth paddling for.

The real window opens up on Friday the 28th. Friday morning brings a light NE breeze at 6 mph, cross-offshore, cleaning up a nice 8 ft SW groundswell with a solid 16-second period. The energy is strong (3365), and the conditions are described as excellent for experienced surfers. This is your best call of the first week. Friday afternoon goes glassy with a 3 mph NNE breeze and 7 ft swell – absolute magic if you can get out. That’s the standout.

Saturday the 29th still has some clean, offshore conditions in the morning with a 5 ft SW swell, but it’s smaller. Sunday the 30th morning is clean again, though only 4 ft SSW, but then Sunday afternoon delivers an 8 ft SSW groundswell with a 20-second period, 6 mph cross-offshore breeze, and exceptional conditions for experts. Energy hits 5405 – that’s a serious lump for a reef.

Monday the 31st goes lumpy again with cross-shore winds, so leave it.

Then there’s a rough patch from Tuesday the 1st of September through to the 3rd – onshore, cross-onshore, and strong winds wrecking the shape. Not for us.

Friday the 5th of September afternoon sees a return to clean conditions: glassy winds with a 8 ft SW swell, period 15 seconds, still solid energy (2802). Another good one for experienced surfers.

But the real highlight in the second week is Sunday the 6th of September morning. An 12 ft SW swell with a 16-second period, light offshore NE breeze at 6 mph, and exceptional conditions for experts. Energy is pumping at 5846. That is a big, clean, powerful swell on a reef – only for the brave, but it’s the best of the whole run. Promising, but we’re 9 days out so keep an eye on it.

After that, the last few days are blown out by strong onshore and cross-shore winds with 12 ft to 13 ft swells. That’s more kite-surfing territory than paddle surfing.

So to wrap it up: Friday the 28th of August is your sure-fire bet for clean, powerful waves. Sunday the 6th of September is the long-range standout if the wind plays ball. Don’t bother before Friday.
