Flatrock Surf Forecast and Surf Report

Alright, surfers, Rusty here. Let’s get into it. We got a solid window of southwest groundswell lining up for Flatrock over the next couple of weeks. It’s gonna be a wild ride, but not for everyone, so let’s be smart about it.

Right off the bat, the water temp is sitting at 59°F, which is about average for this time of year, so don’t expect any surprises.

The big news is Wednesday, August 12th. We’ve got a massive southwest swell (16s period) roaring in, pushing 16.4ft in the morning and still a solid 14.8ft in the afternoon. The energy reading is through the roof at (20415) and then (18746). This is the biggest pulse of the whole window, but it's way too much for this reef. Only the most experienced chargers should even think about it, and even then, it’s going to be a washing machine. Wind is cross-on, so expect it lumpy and unruly.

Thursday the 13th eases off a bit to 11.5ft, but it’s still a serious amount of water and the conditions are messy with onshore winds. Not a day for the faint of heart.

Now, this is where it gets interesting. Friday morning, August 14th, is the standout. The swell has backed down to a still-chunky 11.5ft from the SSW, but the wind is forecast to go glassy. Absolutely dead calm. The energy is (6262), which is still a lot, but with conditions like that, Flatrock is going to be firing with clean, powerful lines. For advanced surfers, this is as good as it gets. It’s a bit much for anyone who isn’t solid, but for the crew who can handle it, get on it early. The afternoon gets a bit of a cross-shore breeze, so the morning is the call.

The weekend, August 15th and 16th, sees the swell ease. Saturday morning has 9.8ft with a gentle offshore wind, keeping things clean. By Sunday, it’s down to 6.9ft, and the offshore wind continues. These days offer better conditions for a wider range of experienced surfers, with the quality remaining high. It’s a good run of clean, powerful surf.

As we roll into the middle of next week, the swell drops but the conditions turn really clean. Monday the 17th and Tuesday the 18th have 5.9ft to 6.2ft of southwest swell with consistent offshore winds. This is a nice, manageable size for good surfers, and the line-up should be more forgiving. It’s not the size of Friday, but it’s looking fun and rippable.

There’s a bit of a dip around Wednesday the 19th with smaller 4.3ft surf and less favorable winds, but it’s a short lull. By Thursday the 20th, a new pulse of southwest groundswell (17s) fills back in to 6.9ft, with clean conditions in the morning.

The next standout is Friday morning, August 21st. The swell bumps up to 8.2ft and the wind is offshore again. This is another excellent window for experienced surfers – bigger, but clean. The energy reading is (2945), so it has some punch.

Following that, things get a little messy. The winds turn onshore for part of the weekend, and while there’s still swell, it’s not the quality we saw earlier. Sunday the 23rd has some rain and strong winds, so that’s a good chance to do something else.

Looking further out to the second week, around Monday the 25th and Tuesday the 26th, there’s another big pulse expected. Tuesday afternoon, August 26th, looks enormous again, with 16.4ft of southwest swell and energy readings over (17382). Like the big day on the 12th, it’s too big and the wind will be chopping it up. Again, one for the experts only, and even then, be careful.

All in all, the next 16 days have plenty of action. The clear standouts are the glassy Friday morning on the 14th for the big-wave crew, and then the clean conditions with solid size next Friday morning, August 21st. The rest of the time, there will be waves, but you have to pick the mornings when that offshore breeze shows up to get the best of Flatrock.

That’s it from me. Stay safe out there.
