Rhosneigr Surf Forecast and Surf Report

Alright, folks, it’s Rusty here. Let’s be straight with you: the next couple of weeks are looking pretty grim on the surf front in this neck of the woods. We’ve got a long stretch of tiny, weak waves and messy winds ahead, so don’t get your hopes up for any classic sessions. We’re going to have to be patient.

The short-term forecast is a real bummer. For the first few days, we’re looking at waves barely bumping the sand – nothing over 2 feet and with weak energy readings in the teens and twenties (like 24 and 18). The wind is mostly cross-off or offshore, which would usually be a good sign, but there's just no swell to work with. It’ll be clean, but you’ll be bobbing around on a lake. The only real positive is that the water temperature is running much warmer than usual for this time of year, about 5°F warmer than average, which is pretty notable.

This flat spell stretches right through the rest of the week and into the weekend. From Friday the 21st through to Monday the 24th, the swell size is pinned at a pathetic 0.3 feet. The energy is bottoming out too, sometimes down in single digits. Even with light winds, there is absolutely nothing to ride. If you blinked, you'd miss the wave period readings. This isn't just a poor spell; it's a full-blown drought.

We start to see a pulse of something early in the second week, but it’s not pretty. Around Wednesday the 26th, there’s a bit more water moving, but the wind swings onshore, creating choppy, messy conditions. It stays poor through the 27th and 28th as the wind strengthens from the west, whipping up some sizable, but completely unsurfable, slop. By late on the 28th, we see the swell energy climb past 100 (148) for the first time, but the strong cross-onshore winds at 25 mph are going to turn it into a complete washing machine. The reading is still "poor surf conditions" and honestly, with that wind, the setup looks more interesting for kitesurfing than paddle surfing.

The weekend of the 29th and 30th serves up more of the same – onshore winds with waves building to around 6 feet, but it’s all short-period, wind-driven junk. The energy gets up there – 291 on Saturday afternoon – but with a 6-second period, it’s just a close-out, lumpy mess. This is only for someone desperate, and even then, you're not going to have any fun. The conditions remain poor.

The start of the next week, the 31st and 1st of September, doesn't offer much of an escape. The swell is still coming, but it's constantly crossed-up and messy. There's a lot of water moving, but the quality is just zero.

Towards the beginning of the second week, we finally see a glimmer of hope. On the 2nd of September, there’s a 7 foot swell pushing in, but an onshore wind ruins it. However, by the 3rd, the wind goes cross-off from the NNW while the swell holds at 7 feet from the SW. This is going to create some heavier, more powerful surf, and it might actually be the most legitimate window of the whole period. The energy is strong, reading at 328. However, at this size with a 6-second period, it’s not a beginner wave—you’ll need to know what you’re doing, and the crowd might be out for the few clean ones. The late-afternoon sessions on the 3rd fade quickly, and by the 4th, the swell starts to drop but with that cross-off wind, it could still have some fun, clean lines before fading out.

So, there you have it. It’s a pretty sad outlook overall. The first few days are totally flat, and most of the second week is blown out by onshore winds. Your only real chances for something half-decent are the 3rd and 4th of September, when a proper-size swell meets a favorable wind direction. Keep an eye on that, but don’t hold your breath for anything classic. We might just have to wait this one out.

Rusty, out.
