The Lowdown
Alright, let’s get into it. I’ve scanned the charts for the local line-up and, honestly, it’s a pretty bleak run ahead for Aberystwyth harbour trap. The next 16 days are looking like a write-off for anything decent, so let’s talk about what’s actually happening.
We’ve got a stretch of flat, weak, and messy surf right from the start. The first record of note is on Sunday the 26th of July, but that’s nothing to get worked up about. There’s a tiny 3ft swell from the WNW with a short period of just 6 seconds – that’s windswell, not groundswell, and combined energy is weak at 65. It’s onshore wind at 16 mph from the WNW, so it’ll be choppy and poor. The water temp is sitting at 66°, which is a whopping 6° warmer than normal for this time of year – that’s very unusual, almost like a warm bath for a Welsh reef, but it won’t make up for the lack of quality.
From the 27th right through to the 3rd of August, it’s a string of tiny swell, mostly 0.7ft to 3ft, all with short periods of 4 to 6 seconds. The wind is almost always cross-onshore or onshore, and the combined energy barely climbs above 30. There’s a brief glimmer on the 30th of July morning with a 4ft swell, but the wind’s cross-onshore at 16 mph, making it choppy and unrideable. Expect a lot of blown-out, bumpy conditions.
Then from the 4th of August through to the 10th, we see occasional cleaner conditions – for example, the morning of the 4th has a light cross-offshore wind (9 mph from the S) and a 1.0ft swell with a 10-second period, so the water might look glassy, but the swell is far too small to paddle. The same goes for the 10th of August morning, with a clean cross-offshore and only 1.0ft. None of this is surfable.
Overall, there are zero good surf options across the entire 16-day window. Aberystwyth harbour trap is a fairly consistent reef, but this forecast is a dead run. It’s the kinda stretch where you leave the board at home and take a long walk instead. forecasts can change, but for now, it’s a blank.
Stay patient,
Rusty.
