Flatrock Surf Forecast and Surf Report

Alright folks, Rusty here, with a look at the local scene. We've got one break to talk about, and it's a bit of a rollercoaster.

First off, Flatrock is a reef break, suited for the advanced crew, and it’s fairly consistent. The water temp is sitting at 59.0°F, which is right on the money for this time of year, no surprises there.

Now, the pattern. We kick things off on Monday, the 10th of August, and it’s not for the faint of heart. The combined energy is absolutely massive at 22849, with a solid 16.4ft SW groundswell pushing in, riding a long 17-second period. The wind is a fresh cross-onshore though, so it’s going to be lumpy. That 16.4ft mark is serious – definitely expert territory only, and that long period means it'll be lining up better on the reef than it would on a beach.

The whole first week is a mixed bag. Monday afternoon drops off to nothing. Tuesday and Wednesday are blown out with strong winds, even though the swell sticks around. The best windows start to show late in the week. Friday the 14th is a bit of a tease, with cleaner conditions and a decent 13.1ft SW swell, but the call is still marginal.

The standout period, and the one I'd circle on your calendar, is Saturday the 15th through Monday the 17th. Things finally align. Saturday morning sees a 9.8ft SW swell with a cross-offshore wind, keeping it clean for the experienced crew. The energy is still strong at 4474. It’s not a huge drop in size, but that offshore flow makes all the difference. Sunday the 16th drops a touch to a 7.5ft SW, still clean with cross-offshore winds. But the real gem is Monday the 17th. The morning has a gentle 4.6ft SW swell with a clean offshore wind, and then Monday afternoon goes glassy. It’s the calmest and cleanest of the whole run, with a 6.2ft SW swell and a 16-second period – perfect for getting some long, smooth lines on the reef. The energy is manageable at 2058.

After that, it gets marginal again through the middle of the month. Tuesday the 18th to Thursday the 21st is mostly messy or choppy with onshore winds. A big low-pressure system moves in on Friday the 22nd of August, bringing gale-force winds and a blown-out 11.5ft swell. That one’s a write-off. The last few days of the period are just poor conditions all round.

So, the call is this: If you’re an advanced surfer, your best bet is Saturday the 15th and Sunday the 16th for solid, clean waves, but the absolute best session of the whole 16 days looks like Monday the 17th of August, especially the afternoon glass-off. Don't sleep on it.
