The Lowdown

Alright folks, it’s Rusty here. Let’s be straight with you – if you were hoping for a week of pumping waves and empty lineups, you’ve come to the wrong place. This stretch we’re looking at is a proper flat spell, a real test of patience. We’ve got a long gap on the cards with next to nothing rideable, so don’t be surprised if the boards stay in the shed for a good while. There’s possibly a brief window of something rideable mid-period, but it’s not going to be pretty.

The first real chance of anything at all is Monday the 14th. The water’s a touch warmer than normal for this time of year, which is something, I guess. Monday morning starts off small with a southwest swell pushing 4ft, but the wind’s howling onshore out of the south at 19 mph, making things lumpy and messy. Not great. The afternoon picks up a bit more energy, with the swell jumping to 6ft from the SSW, and the combined energy gets up to 202, so there’s some push there. But the wind is even stronger, a solid 28 mph, and it’s all over it like a rash. The whole setup is just blown out. For a beginner, this is way too much; for the experts, it’s a wild, bumpy mess. This might be one of those days where the kites are having more fun than the surfers.

After that, the bottom drops out. Tuesday the 15th is a write-off, with the swell fading fast and the wind still howling onshore. The rest of that week slips away into tiny, weak surf and more wind, with the energy readings dropping into single digits and the swell heights barely a ripple. You’re looking at days of 0.3ft to 2ft with no real power behind them.

The following weekend and into the next week is just flat. From Friday the 18th, right through to Monday the 21st, there’s just no swell at all – the energy numbers are basically zero, and the job is a complete blank. It’s just one of those stretches where the ocean takes a holiday.

There is one late glimmer, though. On Tuesday the 22nd, the swell tries to make a come-back, with a 3ft southwesterly swell showing in the morning. But, as you’d expect, the wind is cranking onshore again, this time at 28 mph, gusting up to 31 in the afternoon. It’s a complete washout. So, there you have it. Not a single day in this whole 16-day window that I’d get excited about. It’s flat, it’s windy, and the surf quality is just poor across the board.

Keep the faith, though. This kind of blank run never lasts forever, and the ocean will find its rhythm again. But for now, it’s a waiting game.

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.
