Alright folks, it's Rusty here. Let's have a look at what's on the cards for the next couple of weeks.
To be straight with you, the next two weeks are looking pretty grim. We are staring down the barrel of a long, flat spell. From now until the 26th of July, there's nothing worth paddling out for. The combined energy is stuck at zero or a few single digits, with swell heights barely a ripple. It's a proper dead spell, so save your wax and give the boards a rest.
Things start to show a pulse right at the very end of the outlook. Sunday, the 27th of July, brings a bit of life. The swell is building, but it's messy. We're looking at a 8ft SSW swell with a short period of 8 seconds. The combined energy is moderate (843), but the wind is a gentle cross-shore, which will keep it from being total chaos. That said, it's a big, short-period swell that will be hard to handle. Rhosneigr itself is a beginner-friendly spot, so this size is too much for beginners and only really for the experts who know the sandbar. The setup looks more interesting for a kite session than a paddle surf. The water is sitting at 62°, which is a touch warmer than normal for this time of year.
Honestly, there's no standout session here. The only action is on the last day, and it's a marginal call at best. Keep an eye on the forecasts, because it tends not to stay this flat forever.
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.
