The Lowdown

Alright folks, Rusty here. Let's have a good look at the waves on the cards for Fishermans (Rhiw). Straight up, I gotta be honest with you – it's a grim picture for the next couple of weeks. There’s a long, dry spell ahead with barely a ripple to get excited about.

The overall pattern is one of persistent small, weak, and poor-quality surf. We're looking at a stretch from now, the 5th of August, all the way through to at least the 20th, where every single reading in the forecast is marked as poor surf conditions. That's a solid 16-day gap with no real recommendations, which is a tough run for this area. The water temperature is sitting at about 63°, about a touch warmer than normal for this time of year.

Let's break down the first week. Starting Wednesday afternoon the 5th, we've got a 4ft WSW swell but it's short-period windswell at 5 seconds, with a strong 19 mi/h cross-on westerly. The combined swell energy is weak at only 98, and it's gonna be lumpy and messy. Not worth getting wet for. Thursday the 6th drops off to a tiny 2ft with a cross-shore breeze, and it's all downhill from there. Friday, Saturday, Sunday... it's all onshore winds and tiny, weak swells under 2ft, with energy readings barely hitting double digits. There is a moment on Monday morning the 10th where the wind goes glassy from the NNW, but the swell is a pathetic 1.0ft. Clean, yes, but unsurfable.

Into the middle of next week, the 12th and 13th, we get a little bump in period to 8 and even 10 seconds, but the height is still a tiny 0.7ft to 2ft. We see a glassy morning on the 13th and 14th, with clean conditions from a NNW offshore on the 15th, but again, the energy is just not there (combined energy of all swells is between 18 and 33). You'd be floating.

The second week doesn't offer any hope either. By the 17th and 18th, the wind swings onshore and even gets up to a strong 28 mi/h cross-shore with rain on the 18th. There's a pulse of very long-period groundswell on the 19th (15 to 16 seconds), but the height is a pathetic 0.3ft, so that energy is basically non-existent. The last days, the 20th, see a bump back to a 3ft SW swell, but it's getting crushed by a strong 19 mi/h cross-on wind and then a near-gale on the 20th afternoon.

Honestly, lads, there's not a single standout session in this entire 16-day outlook. The combination of tiny swell, poor wind direction, and mostly weak energy (with the combined energy of all swells never topping 98) means there are no waves to speak of for Fishermans (Rhiw). It’s a total blank run. The best you can hope for is that forecasts change, because it tends not to stay this poor for long. But for now, leave the board in the shed.

Rusty.
