The Lowdown
Alright mates, Rusty here. Let’s get real about Rhosneigr over the next 16 days – it’s a total dud. There’s nothing worth paddling out for. The whole forecast is stuffed with "poor surf conditions" and scores of zero. It’s one of those dry spells we get now and then, not unusual for this area.
We kick off on Saturday, 25 July, with a tiny 2ft swell from the west, a short 4-second period, and a south-westerly breeze blowing straight onshore. The combined energy is a pathetic 18. Weak, messy, and pointless.
Sunday 26 July brings a bit more size – 5ft from the WNW with a 6-second period and moderate energy (138) – but a fresh 18 mph cross-onshore wind makes it lumpy and choppy. No thanks.
The rest of the first week is the same story: tiny swells, short periods, and onshore or cross-onshore winds. There’s a glassy moment on Wednesday 29 July morning, but there’s zero swell. Flat calm for a paddle, not for surfing.
From Wednesday 29 July afternoon through the end of the first week, it’s a gap of flat, tiny, or blown-out conditions. No recommendations at all.
Then on Sunday 2 August, things get wild but not in a good way. A 8ft swell from the SSW with a 10-second period shows up, combined energy hitting 1333 – that’s serious power. But the wind is a near gale from the SSW at 31 mph, cross-onshore, and it’s completely blown out. This is a kite-surfing setup, not a paddle-surfing one. All power, no quality.
The last week of the forecast stays flat and light. There’s a clean moment on Friday 7 August with a light cross-offshore breeze and a tiny 3ft swell, but it’s a 4-second period, weak energy (21), and no push.
The standout? There isn’t one. The water temperature on 25 July is 62°, which is a touch warmer than normal for the time of year, so if you’re just swimming, it’s okay.
Other than that, keep the board in the car. Forecasts can change, but right now, I’m staying on the beach.
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.
