The Lowdown

Right then, let’s have a look at what's on the table for Fishermans (Rhiw). I’ll be straight with you – it’s a tough stretch ahead. The next two weeks are looking pretty bleak for any proper surfing. The water temp is sitting about average for the time of year, so at least you won’t freeze while you’re waiting.

We’ve got a long gap right from the start. There’s nothing worth paddling out for over the first week and a half. From Friday the 14th all the way through to Tuesday the 25th, the swell is tiny, mostly under 2 ft, and the energy is weak as weak can be (single-digit energy readings). The only real highlight in that period is Tuesday the 18th morning, when it goes glassy and the swell bumps up to 3 ft, but even then the conditions are labelled poor and the energy is only 48 – not enough to get excited about. You’d be better off staying on the beach.

Now, after that long dry spell, things start to look a little more promising around Wednesday the 26th. The morning is clean with offshore wind, and we get a 3 ft swell from the SW with a period of 5 seconds – short period, so it’ll be a bit choppy and won’t have much push. The energy is moderate at 41. Not a standout, but at least it’s rideable.

The real standout of the whole 16-day window lands on Wednesday the 26th afternoon. We’ve got 5 ft of SW swell with a 5-second period, and the energy climbs to 114 – moderate wave energy. The wind is cross-off from the NNW, so the wave faces should be clean. For a reef break that’s fairly consistent, this is the one to aim for. It’s not huge, but it’s the best we’ve got.

After that, the surf drops off again. Thursday the 27th and Friday the 28th are back to small, weak, and messy with onshore winds and choppy conditions.

So, to sum it up: don’t bother for the first 11 days. Mark your calendar for Wednesday the 26th afternoon. That’s your only real shot at a decent session.

Rusty.
