The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks.
Right off the bat, I’ve got to be straight with you – it’s a pretty grim start. We’re looking at a solid run of flat, messy, or just plain poor conditions. From now through to the end of July, there’s honestly nothing worth paddling out for. The swell is tiny, the wind is mostly onshore or cross-onshore, and the energy is weak. We’re talking about 9 days of waiting for anything surfable to show up.
The first real glimmer comes on Friday, the 31st of July, for the afternoon. Rhosneigr finally gets a bit of a pulse. The wind swings offshore from the NE, cleaning things right up. We’ll see a 4.6 ft swell coming from the S, with a period of 5 seconds. It’s not a groundswell, but that moderate offshore breeze will make it rideable. The combined energy is moderate (102). Don’t get too excited though – it’s still just surfable, not epic.
Saturday the 1st of August morning is worth a mention too. The wind stays offshore from the ENE, and the swell drops to 2.3 ft from the SW. The period bumps up to 8 seconds, which is a bit better. The energy is weaker (67), but it’ll be clean. Again, it’s an ordinary option.
After that, we hit another slump. The 2nd and 3rd of August are tiny and mostly cross-offshore or onshore. Then on Tuesday the 4th, it goes flat. There’s a big spike in swell on the 5th of August, with heights hitting 8.2 ft from the SW and a period of 7 seconds. The energy is strong (595), but the wind is a fresh cross-onshore, making it lumpy and poor. That one is for the experts only, and even then, it won’t be pretty.
Later in the afternoon on the 5th, the swell is still big at 7.5 ft from the SW with a 9-second period, and the energy is very strong (1143). But again, the cross-onshore wind and choppy conditions make it marginal. The rest of the outlook fades back into small, weak, or clean but tiny surf. For a beginner-friendly spot like Rhosneigr, this is a tough run. The best bet is honestly that Friday afternoon and Saturday morning window.

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.
