The Lowdown

G'day, Rusty here, and I gotta be straight with you – the surf forecast for the next couple of weeks is a bit of a heartbreaker. We're looking at a long, dry spell with barely a ripple, so don't get your hopes up for anything decent for a while.

The first real mention of anything surfable doesn't pop up until Sunday, the 30th of August. Even then, it’s a bit of a mess. On that Sunday morning, we’ve got a 5ft swell from the southwest, but the wind is a moderate cross-onshore, making it choppy. The wave energy is solid, but the quality is poor. The afternoon cleans up a little, with a 8ft swell from the southwest and a gentle cross-shore, giving it a slightly better chance, but it's still only marginal. That swell is a bit short in the tooth at 7 seconds, so it won't have much grunt.

Monday the 31st of August sees a similar story, but the swell gets bigger and a bit more westerly. We’re looking at 8ft from the west-southwest, but the wind is still cross-onshore and choppy. This is getting into the territory where it's only for the experts. The energy is pumping, but the conditions are just plain ugly.

We finally get a bit of a breather on Tuesday the 1st of September. The morning offers a 5ft swell from the northwest with a clean cross-offshore wind. The conditions are described as "surfable waves but very ordinary". It’s not a standout, but it’s the cleanest we’ll see all week. The afternoon is similar but smaller.

After that, it all fades away again. The rest of the forecast is a total write-off, with tiny swells and messy onshore winds. The whole period is a real bummer, with long gaps of nothing. For the beginner crowd, the early part of the week is too small anyway, and the bigger stuff is too rough. Honestly, it's a tough outlook.

Alright, keep an eye on the sky, but don't hold your breath. Until next time, this is Rusty signing off.

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.
