The Lowdown
Alright, listen up. The next couple of weeks here are going to test your patience. We’ve got a long stretch of onshore and cross-shore wind, lumpy chop, and surf that’s just not cooperating. It’s a classic run of poor conditions that’ll have you checking your wax more than your watch.
The first real glimmer of hope doesn’t show up until Saturday the 12th. Even then, it’s marginal. We’re looking at a jump to 8ft of SSW swell, but it’s coming with a cross-shore wind and a bunch of chop. The energy is strong (4001), but it’s messy. This is more of a “maybe if you’re desperate” situation, not a “drop everything and go” one. That size is also getting into the territory where it’s too much for the beginners.
The pattern keeps the wind from the SE, mostly as a cross or cross-on breeze, keeping things choppy. There are a few windows over the next week where the swell drops and the period gets long, like Saturday morning the 13th (2ft at 20s) or Monday the 15th, but the wind just kills it. It’s not worth the paddle out for a few close-outs.
Now, if you’re willing to wait, and I mean really wait, the light at the end of the tunnel shows up on Wednesday the 23rd of September. It’s a week and a half away, so don’t book your flights, but the forecast shows the wind finally swings to the east and goes offshore. For the first time in this whole run, we get a clean look at Nera Rivermouth. The swell is a solid 6ft from the SSW with that long-period energy (15s), and the combination of energy (1519) and offshore wind is the standout of this entire outlook. It’s a river mouth, so it’s sheltered and might not be breaking at its best, but with offshore wind, it’s going to be head-high and glassy. This is the one worth waiting for.
The morning of the 24th also looks like it could have some fun waves as the offshore wind lingers, but the swell is backing off. Don’t sleep on that Wednesday morning though.
Honestly, if you’re a beginner, this whole period is a write-off. If you’re an expert with a high-performance board and a lot of patience, the 23rd is your day. For everyone else, keep the board in the car and the stoke in your heart.
