Castles Surf Forecast and Surf Report

Alright, let me put this in terms you might be more used to. I’ve been looking at the numbers for Castles, and it’s a long-range forecast with some dry spells, but there’s one day that’s a real gem.

We start on Tuesday morning, 8 September. There’s a solid 5 ft southwest swell, with a 17-second period, which is a deep-water groundswell with plenty of push. Wind is out of the east at 9 mph, blowing clean off the face. The combined energy is strong at 1388. Water temp is about 60°F, right around the norm for this time of year. For the experienced surfers, that’s the best of the early run.

Wednesday bumps up to 6 ft of southwest swell and a 19-second period, but the wind cranks up to 25 mph, trashing the surface. The energy is massive at 2525, but it’s not surfable for most.

The week quiets down after that. From Friday, 11 September, we see smaller waves—4 ft down to 3 ft—and shifting winds. The energy drops under 1000, making for small, weak waves.

Things pick up again on Wednesday the 16th with a clean 5 ft southwest swell and a 16-second period under a 12 mph offshore breeze. That’s a good window.

But the big one, the real standout, is Monday afternoon, 21 September. We’re looking at a 8 ft southwest swell, with that same 16-second period. The wind goes glassy—nearly calm—at 3 mph from the north-northeast. That’s perfection. The energy is a huge 4631. This size is over 6 ft, so it’s strictly for the experts. It’s a reef, so the long-period swell will produce clean, hollow lines. Crowds are possible. That’s the day to be ready.

After that, the wind gets messy again.

So: the first week has a few decent morning windows, there’s a flat spell in the middle, and then Monday the 21st is the clear standout. Keep an eye on it.
