Table - best surf conditions forecast for Fishermans (Rhiw) over the next 16 days.
Right, Rusty here again. Let's be honest, the next 16 days at Fishermans (Rhiw) are a real grind. We're looking at a long, flat spell before a flash of something decent right at the end. The water is a warm 62°, which is about 4° warmer than normal for this time of year, so that's a bit unusual.
The first chance for a surf doesn't come until Wednesday, July 22nd. Before that, from the 10th through the 21st, it's a brutal stretch of flatness. The combined energy readings are mostly zero or single digits – barely a ripple.
On the morning of Wednesday the 22nd, we finally get a pulse. The wind is a cross-off from the NNW, but the swell is a short-period 5ft from the WNW. The combined energy hits 154 (moderate), but with a period of only 6 seconds, it's going to be messy and unorganized. The afternoon drops to 4ft. It's surfable, but nothing to write home about.
The only standout, the one you've been waiting for, is Friday, July 24th. Both the morning and afternoon see a solid 8ft swell from the WSW with an 8-second period, pumping out 963 and 788 combined energy (strong). The morning has a light cross-shore, but the afternoon is the winner – the wind goes near-calm, just a light cross-off from the NNW. That will make for clean, powerful waves. At 8ft, this is for experts only. The swell direction from the SW lines up perfectly with the optimum for this reef. Be aware that crowds are possible here, so be ready to share.
Saturday the 25th, the wind goes onshore and the quality drops fast as the swell fades.
So, for the love of surfing, be patient. The 24th is your day. The rest is a long wait for a very short, powerful window.
Rusty.
