The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for Rhosneigr.
Right off the bat, I gotta be straight with you – it’s a tough stretch. The whole 16-day window is looking pretty flat and lifeless. We’ve got a real gap of no surf worth paddling out for, basically from the start all the way through. There are a few tiny pulses of energy, but they’re all rated as poor surf conditions, so don’t get your hopes up.
The first week is a write-off. Friday the 31st of July, we’ve got a weak 2ft swell from the west with a period of just 4 seconds – that’s pure wind chop, not a wave you want to ride. The combined energy is a measly 10 (weak). Saturday and Sunday don’t get any better, with tiny 2ft and 0.7ft swells and light winds, but the energy is next to nothing. Sunday afternoon the 2nd of August, the wind goes glassy with a 0.3ft swell from the west and a 9-second period, but the energy is only 2 (weak). You’d be bobbing around doing nothing.
The middle of the week offers a little more hope, but it’s still tiny. Wednesday the 5th of August morning has a 1ft swell from the SW with a 7-second period, and the wind is a clean cross-off from the NNE. The energy is 11 (weak). It’s clean, but there’s just no power. Thursday the 6th is similar with clean cross-off winds in the afternoon, but still only 1ft and 12 energy (weak).
By the second week, we’re looking at long-period pulses that are too small to do anything with. Sunday the 9th of August morning has a glassy 2ft swell from the SW with a 7-second period and 23 energy (weak). It’s glassy, but it’s still a knee-high dribble. The following days are even smaller, with 0.3ft and 0.7ft swells. From the 12th of August onward, the forecast shows no swell height at all – just zeros across the board. The wind is clean, but there’s nothing to surf.
Honestly, for a spot like Rhosneigr, which is an exposed beach break that needs a decent SW groundswell to work, these conditions are a dud. The optimum swell direction is SW, and we do get a few SW pulses, but they’re all too small. The water temperature is about average for the time of year, so no surprises there.
The only real standout here is the clean conditions on a few mornings, but without any swell, it’s a session for paddling practice or a swim, not surfing. Don’t bother packing your board.
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.
