Alright folks, Rusty here. Let's take a look at what's on the table for Fishermans (Rhiw). Gotta be straight with you – this is a tough one. The next couple of weeks are looking pretty grim for any sort of proper surf, and it's a long, dry stretch ahead.
Right from Monday the 6th, we’ve got a tiny, weak 3ft SW windswell with a short period of 5 seconds, and a fairly strong 12 mph onshore wind from the SSW. It's a write-off. The water temp is reading 61°, which is a touch warmer than average for this time of year. We then slide into a flat spell from Tuesday the 7th all the way through to Friday the 10th. There's a few clean, glassy mornings in there, but with swells of only 0.7ft to 1ft and no energy to speak of (energy values around 1 to 14), you’d be better off swimming.
Even when we get a pulse of longer period groundswell from the west around the 13th of July, the size is still only 0.3ft. We're looking at a 19-second period swell on Monday the 13th, which would be a dream at a point or reef, but the combined energy is a weak 11 – it’s just not enough juice to wrap in and break properly. The offshore winds from the NNE are clean, but with no wave to ride, it's academic.
This pattern of tiny, inconsistent west and southwest pulses continues right through to the end of the run on the 21st of July. The biggest hint of life comes right at the end, on Tuesday the 21st, with a 1ft SW swell and an 8-second period, but it's cross-onshore and the energy is still low at 24. It’s a frustrating outlook, I know. For this area, a long blank run like this isn't uncommon, so we just have to wait for the charts to change. There's simply nothing on offer worth paddling out for. Keep the boards in the bag for now, lads.
Rusty.

A general guide to surfing at Fishermans (Rhiw) can be found by selecting the local surf guide option on the grey menu.

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 Fishermans (Rhiw) 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.
