Flatrock Surf Forecast and Surf Report

Alright, Rusty here. Let’s look at what’s on offer for Flatrock.

Flatrock’s looking at a long stretch of swell, no doubt, but the conditions are gonna be a real battle for most of it. The setup is a reef break, exposed to the SW, and the winds are gonna make things ugly for days on end. We’re talking about a solid southwest groundswell rolling in, with periods hanging around the 16-second mark – that’s proper energy, long lines. But for a beach break, that long period can make things wall up and close out too straight. For a reef like Flatrock, it’s better, but when the wind’s on it, it doesn’t matter.

The water temp is 59°, which is bang on average for this time of year – no surprises there.

Thursday the 6th kicks off with the first surfable swell, but it’s not a day to get excited. A 6ft SW swell at 16 seconds (1554 combined energy) with a light cross breeze. It’s not clean enough to call it good, just marginal. The afternoon builds to 8ft but the wind shifts cross-on. Friday the 7th brings a bigger 8ft SW swell with a clean offshore breeze in the morning – that’s the first real window. The energy jumps to 3705, and with that 16-second period, there’ll be some push. But don’t get caught in the afternoon; the wind swings and it goes to junk.

Saturday the 8th and Sunday the 9th are a write-off. Strong onshore winds, rain, and building swell. By Sunday morning we’re looking at 12ft with a near-gale blowing straight onshore. That’s just dangerous and messy. The energy hits 5457, and then 12776 in the afternoon with a 20-second period – massive, but completely unsurfable with that wind.

This pattern of big swell and poor wind carries right through the next week. Monday the 10th sees 13ft swell, but it’s all onshore or cross-on. The energy stays huge, over 9000, but it’s all for nothing. Tuesday the 11th drops slightly to 7ft, but a strong breeze from the north ruins it. Wednesday the 12th is back to 13ft again. It’s a relentless grind of raw energy and bad wind.

Finally, on Thursday the 13th, there’s a moment. A massive 21ft SW swell predicted, with energy at 32,593. The data says the wind and tide are favorable, but that’s a note of caution: 21ft is way too big for anyone but absolute experts. It’ll be a monster. After that, the following Friday and Saturday drop back to 10ft and 12ft, but the wind is still onshore or cross-on, so it’s still poor.

The first true standout in the whole outlook is the morning of Sunday the 16th. After nearly two weeks of junk, the wind finally goes light offshore from the NNE. The swell has dropped to a manageable 7ft from the SW, with a 15-second period (2027 energy). The data flags it as excellent for experienced surfers. If you’ve been watching the forecast, that’s your window. It’ll be clean, lined up, and way less daunting than the earlier giants.

The second good window hits on the morning of Tuesday the 18th. A 6ft swell from the WSW at 14 seconds (1685 energy), and the wind is pure glass off the NE. Clean as a whistle. That’s the one for a board with a bit more rocker and a relaxed paddle. The morning of Thursday the 20th looks bleak again, with a 13ft SW swell and strong onshore wind. On balance, the best of this 16-day stretch is the Sunday morning the 16th at Flatrock – that’s your call to be on it.

Stay patient, keep an eye on the wind, and don't even think about paddling out on the 21ft day unless you’ve got a death wish and a tow-in crew.

Rusty.
