Rusty here again. Let's chew through this next bit.
Honestly, for the first week and a half, it’s a bit of a sad story. There’s barely anything to get excited about. The swell is tiny, the wind is often ugly, and most of the time it's just flat. There is a long stretch from the 3rd of July all the way through to the 11th where the conditions are just terrible for a proper surf. We're talking knee-high slop at best, with cross-onshore winds messing it up. The first real sign of life doesn't show up until the 16th of July, over a week and a half away. That’s a massive gap of flatness.
When we finally get a pulse of energy, it's Fishermans (Rhiw) that gets the nod, and it’s all about the 18th of July. Saturday morning sees a pulse of 4ft swell from the west, wrapping in with a period of 5 seconds. The combined energy is moderate (64), but the real winner here is the wind. It’s light offshore from the north, so it’ll be clean. The set up is a reef break, fairly exposed to the SW, so it picks up that westerly energy alright. It's a beginner-friendly wave when it's small like this, and it looks like a proper, clean little bank. The afternoon holds similar size (4ft) and cross-offshore breezes from the NW. This is the standout window.
The water temps are around 62°F on the 3rd, which is about 4°F warmer than usual for this time of year, so it’s notably warm.
There is nothing else worth paddling out for in that whole 16-day run. The waves are just too small and the wind too average.
Rusty.
