The Lowdown
Alright folks, Rusty here. Let’s be straight with you – we’ve had a proper look at the charts for Rhosneigr and the next 16 days are a tough watch. The swell just isn’t showing up with any real energy and the conditions are against us for most of the run. You’ll be waiting a long time for anything worth paddling out for.
The first recommendation isn’t until the morning of the 5th of August, and even then, it’s not great. We’ve got a solid gap of poor surf right up until that point. The water temperature is sitting at 62°F, which is a touch warmer than normal for this time of year, so at least you won’t be freezing while you’re staring at the flatness.
On the 5th of August (Wednesday) morning, we see a pulse of swell from the SSW at 3ft, with a short period of 7 seconds and the wind blowing onshore from the SW at 22 mph. The combined energy is moderate (170). It’s a bit of a mess, honestly – not clean, and the size is just about doable for a beginner, but the onshore wind will chop it up. The 5th of August (Wednesday) afternoon is even smaller, dropping to 4ft from the SSW but with a weak 5-second period, and energy is low (78). The wind is still onshore. Not recommended.
The 6th of August (Thursday) morning brings the biggest swell of the window – 6ft from the W with a 6-second period, and energy is moderate (224). But the wind is a fresh cross-onshore from the WNW at 19 mph, making it lumpy and poor. This is borderline for beginners. It’s a real shame, because if that wind was offshore, we’d have something to talk about. The 6th of August (Thursday) afternoon drops to 4ft from the W, with a gentle onshore breeze. Still not clean.
The 16th of August (Sunday) morning is the only other period that gets close to interesting – 5ft from the W with a 6-second period, moderate energy (152). Wind is onshore from the WSW at 12 mph. It’s a messy, lumpy prospect. The 16th of August (Sunday) afternoon is similar at 5ft, but the wind swings onshore from the SSW at 19 mph, making it rough.
Honestly, there isn’t a single standout session in this 16-day outlook. The swell directions are all over the place, the periods are short, and the wind is almost always onshore or cross-onshore. For a break like Rhosneigr, which is exposed to the SW, this is a tough run. The setup looks more interesting for kite surfing than paddle surfing, if you’re into that. I’d keep an eye on the longer-range forecasts, but for now, it’s a waiting game. Stay positive, it tends not to stay this poor for long.
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.
