The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the menu for Fishermans (Rhiw) over the next couple of weeks.
Honestly, I’m looking at the charts and it’s a bit of a grim picture. We’ve got a long stretch of flatness or near-flatness ahead. The water is running at 64°F and it’s much warmer than normal for the time of year, which is a little odd for this neck of the woods, but it won’t help you get a wave.
The first few days are a write-off. Swell is tiny, if it’s even there at all, with a combined energy of just 2. That’s barely a ripple. The wind is a moderate to fresh breeze coming from the north and north-northwest, which is cross-offshore, so the water would look clean, but there’s just nothing to ride. This goes on right through the weekend and into the start of the following week.
We finally see a pulse of energy trying to push through around the 25th of July. Saturday morning we might see a 2ft swell from the west, but with a period of only 4 seconds and a moderate cross-onshore breeze, it’s going to be a choppy, unorganised mess. The afternoon bumps up to a 3ft swell from the west-southwest, and the combined energy jumps to 44, but it’s still cross-onshore and messy. Not one for the log.
The 28th of July, Tuesday, might be the best of a bad bunch. It’s still not great, but we’ve got a 3ft to 3ft swell from the west-southwest, with a period of 4 to 5 seconds. The combined energy sits at 35. The wind is cross-offshore in the morning, cleaning things up, but the swell is weak and short-period. It’s surfable for a beginner on a foamie, but you won’t be writing home about it.
There’s a little window on the 3rd of August, Monday. The afternoon goes glassy with a 1ft swell from the west-southwest. The combined energy is only 7, so it’s tiny, but if you’re desperate, you could get a little knee-high slosh on a longboard.
Overall, there’s no standout session here. The whole 16-day window is a struggle. If you’re a kitesurfer, the consistent cross-off winds might give you a session, but for paddle surfing, it’s a flat spell. We’ll just have to wait for the forecasts to change, because it can’t stay this bad forever.
Rusty.
