The Lowdown
G’day, Rusty here. Look, I’ve had a hard look at the charts for Rhosneigr and it’s a pretty bleak 16 days. We’ve got a long stretch of flat water and tiny, weak swell with no real standout sessions. The water is sitting at 63°F which is much warmer than usual for this time of year—over 4°F above normal, which is pretty unusual.
The first bit of anything happens on Friday, 24 July, but it’s pathetic. A 0.5ft lump from the W with a 3-second period and combined energy of just 12 – that’s barely a ripple. Wind is cross-onshore, so it’s choppy and messy. Not worth paddling for.
The days before that—Monday 20th through Thursday 23rd—are completely flat. Four days of zero swell. Then on Friday 24th, we get a 0.4ft, 3-second dribble from the WNW with onshore wind, energy still rock bottom at 8. No go.
Saturday 25th morning is a little better: 0.6ft from the WNW, 4 seconds, and cross-off wind from the NNW keeping it clean. Energy is weak at 12. You could get a knee-high ride, but it’s barely a wave.
Sunday 26th morning has 0.4ft from the SW, 4 seconds, and glassy conditions with light wind from the WSW. That’s the cleanest it’ll be all week, but there’s no push. Energy is 7. If you’re desperate, you could get wet on a foamie.
Monday 27th sees 0.6ft from the SSW, 4 seconds, with light onshore wind from the SW—messy. Tuesday 28th shows a little more: 0.8ft from the SSW, 5 seconds, clean cross-off wind from the NNE, energy up to 37. Still small, but rideable for a beginner on a longboard.
Wednesday 29th has 1ft from the SSW, 6 seconds, but onshore wind from the SW makes it lumpy. Energy is 84—moderate, but wind kills it. That’s the biggest swell of the run, but poor quality.
From there it fades. Thursday 30th has 0.9ft from the SW with strong cross-onshore 30 km/h winds making it lumpy. Friday 31st is 0.5ft and weak.
There’s nothing here to get excited about. The best of a bad bunch is Saturday 25th morning or Tuesday 28th morning if you just want to get a few small, clean ones. But this is a lean stretch—forecasts can change, so don’t write it off completely, but right 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.
