The Lowdown
Alright, Rusty here again. Looking at it from an imperial view, this is a long flat spell for Rhosneigr. The first decent wave doesn’t show up until Friday, August 7th, so we’re looking at a solid week or more of nothing.
Water temp is about 62°F, just a touch warmer than average, so it’s not too bad for sitting out there.
From Wednesday the 30th of July through Thursday the 7th of August, it’s all tiny, weak, short-period junk. The combined energy readings are in the single or low double digits most days – barely enough to push a leaf. Wind is variable, but it doesn’t matter when there’s no swell.
Friday the 7th of August morning is the one spike: a 10ft SW swell, 8-second period, with a combined energy of 1082. That’s a massive wall of water, but it’s too big for this beginner-friendly beach. It’s strictly for experts, and the cross-onshore wind will chop it up. The afternoon of the same day drops to 6ft with a moderate energy of 413, still cross-onshore.
After that, into the second week, the mornings of the 11th and 12th of August offer some 3ft to 4ft SW swell with clean cross-offshore winds. But the combined energy is only in the 70s to 90s, and the period is a short 5 seconds. Clean but weak.
No real standouts for traditional surfing. The only interesting day is the 7th morning, but it’s too big for the break. Kite surfers might like that big cross-onshore day, but for a paddle surfer, this is a quiet period.
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.
