The Lowdown
Right then, let’s have a look at what we’ve got for Rhosneigr.
Honestly, it’s a tough run ahead. The next couple of weeks are looking pretty flat and messy for the most part. We’ve got a real dry spell on our hands, with hardly anything worth paddling out for until we get into September. There’s a big gap of poor conditions right through the end of August.
For the one spot on the map, Rhosneigr, the water is sitting at about 64°, which feels a touch warmer than usual for this time of year, so at least the temp is on your side if you do get wet.
Let’s break it down. Starting Monday the 24th of August, it’s tiny – 0.3 ft of weak, short-period SW swell (energy a measly 12). The morning is glassy with a light ESE breeze, but there’s just nothing to ride. That theme sticks around for days. Tuesday and Wednesday see similar tiny 0.3 ft to 1.0 ft waves, and while the wind is clean or cross-offshore, it’s all for nothing. Thursday is the same story – 0.3 ft with a clean offshore wind, but it’s a waste of good conditions.
Friday the 28th shows a slight pulse, with 3 ft on the morning, but it’s a short period of 7 seconds and the energy is still weak at 71. A light cross-shore keeps it tidy, but it’s barely surfable. Saturday and Sunday the 29th-30th see the swell bump up to 4 ft, but the wind turns onshore and choppy, making a mess of it. By Sunday afternoon, we’ve got 6 ft from the SSW, but it’s a lumpy, cross-onshore disaster with strong winds.
Monday the 31st pushes 7 ft from the WSW, but again it’s onshore and lumpy. That’s getting into size that’s only for experienced surfers, but with the wind so bad, it’s just ugly. The first of September gets even worse – 7 ft of NW swell with a strong cross-onshore breeze making it downright dangerous and messy. The combined energy hits 409, but it’s all power with no form.
We finally get a bit of a breather on Wednesday the 2nd of September. The morning shows 5 ft of SW swell with a clean cross-offshore wind from the NNW. The energy is moderate at 238, but the period is only 7 seconds. It’s a marginal call, but it’s the first time in over a week that the stars sort of align. The waves will be a bit disorganised, but you could find a couple.
Thursday the 3rd of September morning is actually glassy, with 2 ft of weak SW swell. It’s small and ordinary, but with the wind dead calm, it’s about as clean as it gets. Not a standout, just a chance to get wet.
Looking further out, the weekend of the 5th and 6th of September offers a few more marginal windows. Saturday the 5th afternoon has 4 ft and glassy conditions, but again, it’s short period and weak. Then Sunday the 6th gets blown out by a fresh cross-onshore.
The real kicker comes around Monday the 7th and Tuesday the 8th of September. We see a big pulse of SSW swell, hitting 7 ft on Monday and 8 ft on Tuesday morning, with combined energy readings of 281 and a massive 695 respectively. But the wind is a strong, messy cross-onshore. For a beach setup like this, that’s more of a kite-surfing scenario than a clean paddle-surfing one. Only absolute experts should even look at it, and even then, it’ll be a battle.
In short, there’s no true standout here. If I had to pick the best of a bad bunch, it’s the morning of Wednesday the 2nd of September – it’s the only time you get a bit of size (5 ft) with clean, cross-offshore wind. It’s not going to be perfect, but it’s the closest we get. Keep your eyes on the forecasts, because things can always change.

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.
