The Lowdown
Alright, Rusty here. Let's have a look at what's cookin' for Tenby.
Honestly, mate, it’s a bit of a flat spell for the next couple of weeks. We’ve got some small wave windows, but nothing that’s gonna get the heart racing. The water is sitting at 65°, which is much warmer than normal for this time of year – that’s a nice bonus if you’re just getting wet.
The best bit of action, and I mean the only real standout, rolls in on Sunday the 9th of August. Both the morning and afternoon are looking at a clean 5ft swell from the west, with a period of 7 seconds. More importantly, we’ve got fresh offshore winds out of the NW and WNW, so Tenby (South Beach) will have some clean, groomed lines. The combined energy is moderate, hitting 199 and 196 (moderate energy). It’s a bit short period, so the waves might be a little sectiony, but for a beach break in August, you take what you can get. This is beginner-friendly size too, so don't be scared.
Before that, it’s pretty bleak. There’s a solid gap of almost no surf. You get a tiny 0.3ft bump on Saturday the 26th of July morning with offshore wind, but it’s just not enough to do anything with. The Sunday the 9th of August is your only real shout.
So, to sum it up: wait it out. The surf is mostly poor until that Sunday the 9th of August. Keep an eye on the forecasts, but right now, that’s your window. If it’s not surfing you’re after, those strong cross-off winds on a few of the other days might make it interesting for a kite session, especially with the bigger chop around.
Rusty.
