Rhosneigr Surf Forecast and Surf Report

Alright, I’ve had a look through the charts for the next couple of weeks, and it’s a real tough stretch for us. We’re talking about Rhosneigr, and the water’s running a touch warmer than normal for the time of year—about 18°; that’s a couple of degrees above average, so it’s a nice change if you’re getting in.

Right now, from Monday the 31st of August, we’ve got a messy picture. The morning brings a weak swell from the WNW at 4 ft, but that period is a short 5 seconds with a fresh cross-shore wind, creating lumpy, choppy conditions. The combined swell energy is only 149, so it’s weak, and it’s just not coming together. That’s the story for the whole first week, honestly. The swells are small, the wind is onshore or cross-onshore, and every single report says “poor surf conditions.” There’s nothing to get excited about.

We’ll see a bit of a bump in swell size on Thursday the 3rd and Friday the 4th, with the swell hitting 7 ft at times, but it’s onshore wind and the period is still short—around 6 seconds. The energy climbs to 319 and 299, which is moderate, but with the wind smashing it, it’s just a blown-out mess. That’s more for the kite surfers if anything.

The weekend of the 5th and 6th of September stays small and weak, with the wind still cross-onshore and lumpy. The early part of the second week, from the 8th to the 11th, is a total write-off—tiny waves, hardly any energy, and the wind is still messy. There’s even a day with a light breeze and clean conditions on the 12th of September, but the swell is only 0.7 ft to 1.0 ft, so you’re just floating.

Then, late in the outlook, we’ve got a promising pulse showing up on the 13th of September. The swell starts to build again, reaching 6 ft by Sunday afternoon with a 6-second period from the SSW, and the combined energy hits 231 (moderate). The wind is light, which is a big positive. By Monday the 14th, it’s still around 6 ft, but the wind turns onshore and fresh. The real standout might be on Tuesday the 15th of September—the morning brings a 8 ft SSW swell, with an 8-second period, and the combined energy is a strong 640. That’s a proper swell, but it’s also blown out by a strong onshore breeze at 28 mph. This is expert-only territory, and even then, it’s going to be a wild, choppy beast. It’s a long way out, so keep an eye on it, but don’t book the day off yet.

In short, we’ve got a long gap of nothing good until the 13th, and even then it’s a gamble. The 15th has the best size, but the wind will ruin it. For now, keep the board waxed and wait for the next forecast.
