The Lowdown
Alright, folks, Rusty here. Let’s break down the surf outlook for Tenby (South Beach). There’s a bit of a dry spell before anything good shows up, so you’ll need to be patient.
The first week is a total bust. From the end of July through the first week of August, the surf is poor. The waves are tiny, mostly under 2 ft, and the energy is weak, with the combined swell energy topping out at just 48 on the Saturday morning. The wind offers some clean moments, like Friday morning, 31 July, with glassy conditions and 2 ft, but there’s just no power behind it. The period is short, mostly 4 to 10 seconds, so the waves are limp and mushy. Not worth paddling for.
The first real chance comes on Monday, 10 August. The morning brings a jump to 5 ft from the WSW, with a 9-second period, and the combined energy hits 378. The wind is a clean cross-off from the WNW, so the surf is rideable, but conditions are still described as very ordinary. The afternoon gets a bit bigger at 6 ft, but the wind picks up and the quality is marginal.
Now, the standout session is Tuesday morning, 11 August. We’re looking at 7 ft of swell from the SW, and the wind is dead calm – glassy as glass. The combined energy is a solid 407, so there’s plenty of punch. The period is only 7 seconds, which is short, so it’ll be a bit lumpy and tight, but for a beach break, that’s fine. At 7 ft, this is strictly for experts; it’s way too big for beginners. The water temperature is a notable 66°F, which is a whopping 5° warmer than usual for this time of year, so that’s very unusual – you might be fine in a shorty.
The days after, from Tuesday afternoon through Wednesday, 12 August, keep the size around 7 ft to 7 ft, but the wind shifts cross-off or cross-shore, and the quality drops back to marginal. The combined energy even reaches 619 on Wednesday afternoon, but the conditions are messy, so it’s not as clean as Tuesday morning.
So, the first week is a blank. The only real highlight is that Tuesday morning, 11 August, for the experienced crew. After that, the swell sticks around but the wind doesn’t play as nice. Keep an eye on the forecasts – the area is fairly consistent, so it never stays flat for too long.
Rusty, signing off.
