Alright folks, Rusty here. Let’s break down what’s happening at Tenby (South Beach) for the next couple of weeks. I’ll be straight – it’s a tough outlook for surfers.
We start with nothing on offer. From Saturday the 4th of July all the way through to Saturday the 18th of July, it’s a long, flat run. The swell is tiny, mostly under 2ft, and the wind is often cross or cross-offshore, but there’s just no power behind it. The combined wave energy is weak, staying mostly in the double digits.
There’s a slight lift right at the end, on Sunday the 19th of July. We see a 4ft swell from the ESE, but with a period of only 5 seconds, it’s just short-period windswell – not going to be clean or powerful. The water temperature was recorded as much warmer than normal back on the 4th, hitting 64°F with a 5°F anomaly – that’s notably warm for the season.
Honestly, there’s no standout session in this whole 16-day window. The swell is too small and weak to get any real rideable waves. Even the longer-period groundswells that show up are only 0.3ft – just ripples. For a sheltered spot like this, that’s a total washout.
Best leave the board at home for now. It’s a proper flat spell, and it might be a while before anything changes.
Rusty.
