The Lowdown

Alright folks, Rusty here. Let's be straight with you—looking at the 16-day forecast for Rhosneigr, it’s a pretty quiet start. We’ve got a long stretch of weak, small, and mostly poor-quality surf to get through before anything worthwhile kicks in.

The First Week: A Waiting Game

For the first ten days, from Monday the 10th right through to the end of the weekend on the 17th, it’s grim. Swell heights barely climb above 2 ft, with periods that are often short (4-6 seconds) or weirdly long (12 seconds) but with no power behind them. The combined wave energy is very weak, mostly single or low double-digits (9, 5, 1). The wind is a constant problem too—mostly cross-on, onshore, or just not clean enough to make anything of the tiny bumps. There’s nothing worth a paddle out there. We’re talking about a solid 8-day gap with no real recommendations.

Tuesday the 19th is the first day where things start to twitch. The morning goes glassy with a 3 ft swell, but it’s still very weak (38 energy). The afternoon is the first real flicker of hope: a 5 ft swell from the SW (133 energy) with a gentle offshore breeze. The call is "surfable but ordinary," scoring just a 1. The waves will be there, but it’s not going to be one for the memory bank.

The Second Week: One Clear Standout

The following week is still mostly small, but the end of the run has one proper standout. Wednesday the 20th through Sunday the 24th is dominated by tiny 0.3 ft swells, though with some very long periods (13-15 seconds) and clean offshores. The energy is still weak (8-20), so it’s really just ankle-biters that are clean but empty.

Then we get to Monday the 24th of August. This is the one. The morning brings a 5 ft swell from the S (153 energy) with a moderate offshore wind. It’s "surfable but ordinary," but the afternoon is where it’s at. Swell jumps to 7 ft from the S with a period of 6 seconds, and energy rockets up to 389. The wind stays a clean, moderate offshore. The call is "expect good surf conditions," scoring a 2 out of 10. For this whole run, that’s the best we get. At 7 ft, it’s getting solid—steer the beginners away from that one. It’s an exposed break, so it’ll handle that size, but with a short period, it might feel a bit lumpy and fat. Still, it’s the only day with real push and clean wind. Tuesday the 25th drops back down to 3 ft (76 energy), so that Monday afternoon is the clear winner.

Rusty.

Information about the Rhosneigr Surf forecast

The above surf forecast table for Rhosneigr provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Rhosneigr can be found by selecting the local surf guide option on the grey menu. Our Rhosneigr surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Rhosneigr) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Rhosneigr may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
