The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this outlook for Rhosneigr is a tough one. We’ve got a long stretch of flatness and poor conditions ahead, so you’ll need patience.
The water is sitting at a warm 63°F, which is a couple of degrees warmer than usual for this time of year – feels like a summer bath.
For the first week and a half, there’s nothing worth paddling out for. From Thursday 16th July through to Friday 24th July, the swell is tiny – we’re talkin’ 0.3ft to 1ft at best, with short periods and weak energy (combined energy readings mostly in single digits or low teens). The wind is mostly cross-off or cross, but there’s just no wave to work with. It’s a real bummer.
Even going into Saturday 25th July, we finally see a bit more push – 3ft from the NW early morning, with a period of 5 seconds and combined energy of 42 (moderate). But the wind is cross, and the forecast still calls it “poor surf conditions.” That’s a small, short-period swell with messy texture. Not a standout.
The next few days after that see a small bump of 2ft to 3ft from the SW, but it’s all cross-on or onshore wind, and the periods are short (3 to 6 seconds). The energy is weak to moderate at best (69 is the highest towards Wednesday 29th July). The wind picks up strong – 19 to 22 mph on Wednesday 29th – making it choppy and lumpy. Honestly, with the wind and small, weak swell, this setup looks more interesting for kite surfing than paddle surfing.
There is no standout session in the entire 16-day window. The best you can hope for is a small, bumpy ride on the morning of Saturday 25th July, but it’s not worth getting excited about. For Rhosneigr, a blank run like this happens – it’s a fairly consistent spot, but when the Atlantic shuts off, it really shuts off.
Keep an eye on the charts, folks. It tends not to stay 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.
