The Lowdown
Alright, let's break down what’s in store for Fortunes Rocks Beach over the next couple of weeks.
Honestly, it’s a slow start. For the first week and a half, you're not looking at much. Onshore winds, tiny weak swells, and the forecast keeps calling it poor surf conditions. The combined wave energy barely gets into double digits for most of that stretch, so it’s mostly flat, bumpy, or just messy. You’ll be waiting a while.
The first real hint of something surfable doesn't show up until late on the 18th, and even then it’s barely worth a mention. We get a small push of swell to about 4ft from the East, but the period is short at 6 seconds, and there’s a cross-shore wind. The energy ticks up to 115 (moderate), but it’s just not clean enough to get excited about. The best chance that day is the Friday afternoon session on the 18th with a 3ft East swell, offshore wind from the North at 6 mph, and clean conditions. The energy there is only 77 (weak), but the offshore wind will make the most of it.
Now, if you're holding out for a real standout, you have to wait until Wednesday, September 23rd. That morning, we finally get a decent pulse of swell: 4ft from the ESE, with a period of 9 seconds. The combined energy jumps up to 244 (strong) – that’s the most we see in the whole run. The wind is light cross-onshore from the ESE at 6 mph, so it’s not glassy but it’s the best combo of size and energy we get. The water temperature is around 62°, which is about normal for this time of year, so nothing wild there.
Keep in mind, when the swell gets over 5ft it can be too much for beginners, but this is right on the edge, so it’s good for intermediates and up. The 9-second period is solid for a beach break like this, giving you some push without being too straight. Crowds can be a problem here sometimes, so if the forecast holds, expect company.
After that, the surf drops back off into mediocrity with onshore winds and smaller swells through the end of the month. The morning of the 25th has another 4ft ESE swell with offshore wind from the NW at 6 mph (energy 176 - strong), which is a solid option if you missed the Wednesday window. But that’s your two best bets: the 23rd morning and the 25th morning. Everything else is too small, too choppy, or just plain flat.
For kite surfers, some of those windy days with cross-off winds and moderate swell might actually look more interesting than for paddle surfing, especially around the 20th and 26th with strong winds.
So, in short: the first nine days are a bust. Then we get one decent day on the 23rd and a follow-up option on the 25th. After that, it tails off again.
