The Lowdown
Alright, let’s look at Fishermans (Rhiw). It’s a reef break that’s fairly consistent, and it’s a solid beginner-friendly spot when it’s working. We’re staring at a real dry spell for the next week or so, with a proper drought of surf energy. The water is about 63°F, which is a touch warmer than normal for this time of year, so you won’t be shivering while you’re waiting for a wave.
The first few days are a bust. Clear skies and a moderate breeze today, but the combined swell energy is flat at 0. Friday morning sees a tiny 0.3ft swell from the west with a long 13-second period, but the energy is just 3 – it’s barely a ripple. Friday afternoon goes glassy, but with only 0.3ft on offer, it’s a flat spell. Saturday and Sunday bring some windswell, but it’s messy and cross-shore, with the combined energy only reaching 78 on Sunday morning. Nothing to get the heart pumping. Monday through to Thursday the 30th is a real grind – tiny, onshore slop with the combined energy stuck in the single digits. There’s a brief moment of glassy conditions on the morning of the 31st, but with only 2ft from the south and a period of 3 seconds, it’s just a lake.
Now, the first real pulse of interest shows up on the 1st of August. Saturday morning sees a 7ft swell from the southwest with an 8-second period, and the combined energy jumps to 528 – that’s moderate wave energy. However, the wind is cross-onshore from the SSE, making it choppy. Saturday afternoon pushes up to 8ft, with energy at 929, but it’s still cross-onshore and only rated as marginal. That’s big enough for only experts, and the wind is a letdown. The setup looks more interesting for kite surfing than paddle surfing, to be honest.
Sunday the 2nd still has some size, with 4ft in the morning and energy at 235, but the wind is onshore again. After that, it drops right back down to tiny, poor conditions through the rest of the first week of August. The 6th of August shows a very long period 12-second swell from the west, but it’s only 0.3ft – a ghost. The 7th of August is clean but tiny.
So, the honest truth is there’s no standout. The best on offer is the 7ft to 8ft swell on the 1st of August, but it’s blown out and messy. For a beginner, it’s far too big. For a confident surfer, it’s a gamble. The rest of the 16-day window is a flat, windy mess. It’s a tough run for Fishermans.
