Table - best surf conditions forecast for Fishermans (Rhiw) over the next 16 days.
Alright, let me level with you. I’ve had a proper look at the charts and trust me, it’s a tough stretch ahead for Fishermans (Rhiw). We’ve got a long, quiet run on our hands here, so don’t be expecting any heroics.
Right out of the gate we’ve got nothing. No swell to speak of for the first few days. There’s a tiny blip on Thursday morning, 9th July, but that’s a mere 0.7ft swell from the WSW with a period of only 4 seconds – that’s just wind chop, not worth paddling for. The water temperature is sitting at 62°, which is a touch warmer than normal for this time of year. Not enough to make a difference though.
The real story here is a whole heap of flatness. We’re looking at a gap of roughly nine or ten days where there's nothing worth recommending. The energy readings are all single digits – basically, the ocean is asleep. A couple of afternoons see a 0.3ft swell creep in, but they’re either too small, have poor period, or the wind’s in the wrong spot.
Now, for the curious surfer, there’s a slight change around Thursday 16th July morning. We finally get a glassy morning with light offshore winds from the WSW, a tiny 1.0ft swell from the SW with a period of 7 seconds. It’s clean, but the combined swell energy is only 7. That’s weak. You’d be lucky to get a knee-high ripple. Not a standout, just the best of a bad lot if you’re desperate for a paddle.
Then the afternoon of Thursday 23rd July brings a pulse of 5ft swell from the SW with a period of 6 seconds, and combined energy of 123 (moderate wave energy) – but it’s onshore, messy, and it’s a long way off on the charts. It looks more interesting for kite surfing than paddle surfing, honestly.
So here’s the deal: there is nothing on this horizon that’s a true standout. It’s a blank run, which for this area is pretty normal when the swell windows don’t line up. Don’t get too down about it – it tends not to stay poor for long, and forecasts can change.
