The Lowdown
Alright, let’s talk in feet and miles an hour. Rusty here, and this 16-day stretch at Fort Cronkite Rodeo Beach is mostly a bust. We’re looking at a big dead zone up front—nothing worth paddling out for until Thursday, 4 September. That’s a solid two weeks of junk.
The first real chance shows up on the morning of Thursday, 4 September. Combined swell energy is strong at 1003, with a 3ft swell out of the southwest, riding a long 18-second period. That’s groundswell, so you’ll get clean, well-shaped waves with nice spacing. Wind is glassy—calm out of the east at 0 mph. Water temperature is running much warmer than normal at 64°, which is 6° above average. Very unusual for this time of year.
Fort Cronkite Rodeo Beach is a sheltered sandbar that’s very consistent. Crowds are sometimes an issue, but with these clean conditions, expect some company. The swell is small enough for beginners. This morning is your standout.
That afternoon, the wind swings cross-on from the west-southwest at 9 mph, and the swell jumps to 6ft from the west-northwest at 11 seconds. Strong energy at 1921, but the conditions go marginal. After that, the rest of the window is mostly slop—2.1m+ (7ft+) swells from the northwest with short periods and onshore winds. Not worth it unless you’re an expert chasing lump.
Bottom line: wait for the morning of Thursday, 4 September. That’s the one.
