The Lowdown
Alright folks, Rusty here. Let’s be straight with you—this stretch of coast is looking quiet. Real quiet. I’ve been through the next 16 days and there’s nothing I can honestly recommend for a paddle. The finder shows no good surf options in the entire window, so we’re talking about a blank run from now through to the 4th of August.
What we’ve got is a whole lot of tiny, weak swell and mostly cross-onshore wind. The only break on the cards is Aberystwyth harbour trap (Wales). It’s a reef setup, fairly exposed to the swell, but the swell direction is swinging from NNW to WSW and the period is short, mostly 4 to 5 seconds. That’s windswell, not groundswell, so the waves will be weak and crumbly if they show at all. The combined energy of all swells directed here is virtually nothing—mostly single-digit values like 21 (weak energy) on the 20th July, then dropping to 1, 2, or 4 for the rest of the run. The water temperature is 67°, which is 7° warmer than normal for this time of year—very unusual, but it won’t help the surf.
The wind is a problem. From the 20th July onwards it’s mostly cross-on from the NW or NNW, blowing 10 to 16 mph, which messes up any chance of clean waves. By the 24th July we get some onshore wind but the swell is practically zero. There’s a brief moment on the 31st July morning with a fresh offshore from ESE at 22 mph, but there’s no swell at all—zero energy—so it’s just a clean, flat ocean. That’s a bit of a tease.
The 2nd August afternoon shows a tiny bit of life with a cross-off wind and a small 1ft swell from WSW, but the combined energy is only 5 (weak). It’s not enough to get excited about. The rest of the run into early August is more of the same: small, messy, or flat.
This is one of those periods where the forecast is just barren. For a reef spot like Aberystwyth harbour trap, it’s not unusual to have a quiet spell, but it’s still frustrating. Keep an eye on it—forecasts can change, and it tends not to stay this poor for long. But for now, leave the board in the van.
Rusty.
