The Lowdown

Alright, let’s be straight with you. For the next week, it’s a tough watch. Fishermans (Rhiw) is going to be a frustrating place to be. The swell is tiny, and most of the time the wind is just wrong — cross-onshore or onshore, constantly messing up what little wave there is. The water temp is about average for the time of year, nothing unusual there.
The first real flicker of life doesn’t happen until the afternoon of Friday the 31st of July. The wind finally swings offshore from the NNE at 12 mph, and we get a small 4 ft swell from the SSW. The energy is still weak (67), and the period is short, so it’s not going to be a classic, but it’ll be the cleanest wave we’ve seen in days. It’s a beginner-friendly reef, so if you’re just wanting to get wet, this is your window.
Saturday the 1st of August brings a little more hope. The morning shows a 3 ft swell from the SW with a period of 9 seconds, which is a proper groundswell. The energy ticks up to 112 (moderate), and the wind is light and cross-shore from the ESE at 6 mph. While it’s not glassy, it’s clean enough, and that longer period will give the waves a bit more shape. It’s the best on offer, but don’t expect pumping barrels.
The real standout, if you’re an expert and like it big, is Wednesday the 5th of August. The afternoon shows a 8 ft swell from the SW with a period of 9 seconds. The combined energy is a massive 1012 (strong). However, the wind is cross-shore from the W at 12 mph, creating a cross-chop. This is big, powerful, and messy. It’s expert-only territory, and honestly, with that wind, it might be more interesting for the kite surfers than paddle surfers. If you’re a beginner, stay well away.
The rest of the second week drops off again into tiny clean waves with very little energy. There’s a long gap from the 5th to the 9th of August where it’s just not worth paddling out unless you’re desperate for a float.
So, to sum it up: the best of a mediocre bunch is the afternoon of the 31st of July for a clean, small wave, and the morning of the 1st of August for a slightly better shaped, longer period swell. The 5th of August is big and powerful, but only for the brave and experienced.
