Flatrock Surf Forecast and Surf Report

G’day, Rusty here. Flatrock is our only game in town this outlook, a solid reef setup that handles a decent lick of SW swell. The water temp’s sitting at 15°, about average for this time of year, so nothing wild there. First up, there’s nothing worth paddling out for until Tuesday the 8th, so you’ve got a couple of days to sit tight. Let’s break it down.

The first real chance kicks off Tuesday morning, September 8th. Swell’s coming in at 8 ft from the SW with a very long period of 17 seconds – that’s proper groundswell, and it’s packing strong energy (4043). This is prime for a reef like Flatrock, where those long lines will stand up nicely. Winds are light offshore from the ESE, so it’ll be clean. The water temp anomaly is only 0.4°, which is just about normal for the time of year. This is excellent for experienced surfers, and you’ll have the place to yourself if you’re early – crowds are only sometimes an issue. Tuesday afternoon gets a bit dicey with a southerly breeze picking up, so make the most of the morning. Wednesday the 9th sees the swell bumping up to 13 ft from the SSW, with a very long period of 19 seconds and massive energy (9897). This is big, well overhead, and only for experts. Winds are cross-off but strong, so it’ll be clean but tricky. Thursday the 10th offers a standout morning: 12 ft SSW swell with 16-second period, strong energy (5386), and offshore winds from the ESE. That’s clean, powerful, and exceptional for those who can handle it. Friday the 11th drops back to 7 ft, but winds swing cross-off from the NE, so it’s clean and more manageable. Saturday the 12th is a write-off with cross-shore chop and smaller swell. Sunday the 13th brings onshore wind and rain – forget it. Monday the 14th has some cross-shore chop on 7 ft swell, nothing flash. Then Tuesday the 15th morning looks promising again: 8 ft SW swell with 15-second period, light offshore from the ENE, and strong energy (3051). This is excellent for experienced surfers. Wednesday the 16th morning stays clean with light offshore winds and 7 ft swell, and Wednesday afternoon turns glassy – zero wind, 6 ft, and clean. That’s a sneaky good session for the more moderate crew. After that, from Thursday the 17th through Sunday the 20th, it’s messy: strong cross-onshore winds, lumpy conditions, and poor surf. The big standouts are Tuesday the 8th morning and Thursday the 10th morning for the advanced crew, with clean, powerful SW groundswell and offshore winds. For something a bit more mellow, Wednesday the 16th afternoon is glassy and clean. Keep an eye on Monday the 21st – the forecast is hinting at a massive 13 ft, 21-second SW groundswell with light cross-off winds and extreme energy (13835). That’s one for the books if it holds, but it’s a long way out, so stay tuned. No other breaks to mention; Flatrock is the only spot in the mix.

Rusty.
