The Lowdown

Right then, let's have a look at what's on the cards for the next couple of weeks. I gotta be straight with you, it's a real tough watch for Fishermans (Rhiw). We've got a solid 16-day window, but to be honest, the surf is looking pretty average for the vast majority of it. The first real shot at anything worth paddling out for doesn't come until Tuesday the 18th, and even that's a bit of a mess.

From now until then, we're looking at a long stretch of tiny, weak waves. The water temp is sitting at about 64°F right now, which is a touch warmer than normal for this time of year, so at least the dips won't be a shock to the system. But for surfing? It's a real struggle. There's a few days with a clean-looking surface, like Wednesday the 12th afternoon with a light cross-offshore, but the swell is a paltry 0.7ft. It's just not enough to get excited about.

Then, on Tuesday the 18th, we get a bit of a pulse. The morning sees a 5ft swell from the WSW, but it's short period at 6 seconds and the wind is a strong 25 mph cross-onshore. The combined energy is moderate at 181, but it's going to be messy and choppy. That afternoon cleans up, but the swell drops right back down to 3ft.

The one window that might be worth a look, if you're keen, is late in the period. On Thursday the 27th, the afternoon shows a 5ft swell from the SW, with a 6-second period and a moderate offshore wind from the north. The combined energy is moderate at 143, and it's clean. It's not a world-beater, but it's the only time in the whole forecast where the conditions come together for something actually surfable. For a beginner, that 5ft might be a bit on the big side, but for anyone else, it's the best we've got on offer.

Other than that, from the 18th onward, it's mostly tiny, clean waves, but the swell energy is just too low. It's a frustrating outlook for the area, but sometimes you get these blank runs. The forecasts can change, so keep an eye on it, but for now, don't hold your breath.

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.
