Tenby (South Beach) Surf Forecast and Surf Report

Alright, mates. Rusty here. Let’s cut to the chase—this 16-day stretch for Tenby (South Beach) is a rough one. We’re staring down a long, flat spell with only a couple of moments that might get you excited.

The water’s sitting at 67°F right now, which is much warmer than usual for this time of year. That’s a nice little bonus if you’re thinking of a swim, but the waves are a whole different story.

The first week is a total write-off. From Monday the 17th right through to Sunday the 23rd, the swell is tiny, and the models are calling it “poor surf conditions” across the board. Expect flat, weak waves with light wind. There’s a flicker of something on the 20th (Thursday morning) with a 5ft W swell under a clean offshore NNW wind, but it’s still described as “very ordinary.” Not worth paddling out for.

We get a bit more energy through the middle of the second week, but the quality stays poor. On the 27th (Thursday) the afternoon swell nudges up to 6ft from the SW, but with a short period and cross-off wind, it’s messy. The first real standout doesn’t show up until Friday the 28th of August. The morning session is the pick of the entire forecast: a 7ft WSW swell, with a very long period of 10 seconds, combined energy of 766 (moderate), and a clean, light offshore breeze. That’s proper groundswell energy, and the conditions are actually described as “expect good surf conditions.” This is the one to aim for—but it’s over 5ft, so it’s a bit much for beginners, and the long period might make it a bit fat and draining at the beach break. Still, the best we’ve got.

The rest of the run tapers off. The 29th (Saturday) morning offers a 4ft NW swell with clean offshore wind, but it’s “very ordinary.” The 30th (Sunday) morning has a 7ft SW swell, but again, the quality isn’t there. The 31st (Monday) morning sees the biggest energy spike of the whole period—7ft W swell with a combined energy of 1364 (very strong wave energy)—but it’s flagged as “marginal surf forecast” with a risk of thunderstorms and strong winds. That’s a kite-surfing setup if I’ve ever seen one.

So, to sum it up: there’s a long, dry gap from the start until the 28th, and then a short window of interest. The standout is Friday the 28th morning at Tenby (South Beach) in the UK. For the rest, keep your expectations in the parking lot.

Rusty.
