Flatrock Surf Forecast and Surf Report

Alright, Rusty here. Let’s have a look at what we’ve got.

Alright, Flatrock’s looking at a solid run of groundswell through the first week. This is a proper, exposed reef that needs a good SW direction to light up, and it's getting plenty of that. The initial energy is massive with combined swell energy hitting (5892) which is strong, but that drops gradually through the weekend. The water temp is 59°F, which is basically bang on average for the time of year, so nothing wild there.

Friday morning the 14th is the real standout of the whole outlook for this spot. You’ve got 12ft of SW groundswell rolling in with a very long 16-second period, the wind is glassy out of the SSE at just 3 mph. That’s flawless, clean, lined-up reef waves. But listen, at 12ft, that’s serious size – experts only. This is heavy, powerful stuff. Don’t even think about paddling out unless you know what you’re doing.

Friday afternoon the wind swings onshore and the quality drops.

Saturday the 15th and Sunday the 16th clean up nicely with offshore winds, the swell drops from 10ft to 7ft over the two days. That 7ft on Sunday morning is still a solid, clean wave for experienced surfers, but the crowds are possible here, so don’t expect it empty.

Monday the 17th holds 6ft of clean swell with light offshore winds, another good one for those with some time mid-week.

Then we hit a lull. From Tuesday the 18th through Thursday the 20th, the swell drops below 7ft and the wind goes messy or onshore. It’s not worth paddling out. A few days of average conditions.

By Friday the 21st, a new pulse of 10ft swell shows up, but the wind is cross-onshore and choppy. The energy jumps right back up (8289), but the quality is shot. It’s a kite day, not a surf day.

The weekend of the 22nd and 23rd stays messy with lumpy cross-shore winds. Not your friend.

Now here’s the real promise in the long range: Wednesday the 26th of August. That morning looks like a sneaky beauty. Offshore winds from the east at 9 mph, 12ft of clean SW groundswell, period a punchy 13 seconds, and the combined swell energy is a massive (7935). This is another expert-only session, but it will be clean, powerful, and properly good. The confidence is a bit lower this far out, but if it holds, that’s the one to circle on the calendar.

After that, Thursday the 27th and Friday the 28th drop back to 8ft with clean winds, still good for experienced surfers but the real power is gone. Saturday the 29th is small and mellow to finish.

Overall: If you’re an expert, the two absolute standouts are Friday morning the 14th and Wednesday the 26th morning. Both are heavy, glassy, and have that deep reef power. For the rest of us, the weekend mornings of the 15th and 16th are the best bet for a clean, manageable wave.

Rusty.
