The Lowdown
Alright, grab a coffee, ‘cause I’m gonna be straight with you. This is a flat spell, and I mean flat. Looking at the entire 16-day window, there’s not a single standout session worth paddling out for. We’ve got a long stretch of little to nothing on the cards.
First up, we’re looking at Tenby (South Beach). The water temp is sitting about average for the time of year, so no surprises there. But the surf? Mate, it’s a tough watch. From Wednesday 15th July right through, the dominant story is tiny, weak swell. The combined energy of all swells directed here is barely registering, mostly in the single or low double digits, like 46 (weak energy) on the Wednesday morning, dropping to a measly 2 (barely any energy) by Monday 20th July. The swell height is a pathetic 1ft at best, often 0.3ft or 0.7ft. The swell period is all over the place, from a short 4 seconds up to a long 19 seconds, but with that tiny height, it doesn’t matter. Even a long period groundswell like that needs some size to wrap in.
The wind does offer some clean windows, like glassy conditions on Wednesday afternoon and Friday morning, 17th July, with a calm sea. You’ll get some clean, offshore or cross-off breezes here and there, but it’s on a wave that’s barely a ripple. For a beginner-friendly, sheltered spot, this is a total write-off. The break is fairly consistent, but it’s consistently tiny. The crowds are sometimes an issue, but honestly, nobody’s going to be out there for this.
The pattern doesn’t really change. Through the second week, you’ll see a few more 1ft days with a WSW swell, but the energy stays pathetic (16 to 25). The wind stays mostly cross-off or cross-on, but it’s all for nothing. Even the light onshore days won’t produce anything rideable. This is a solid 16-day gap with no recommendations. For an area like this, a blank run this long is a bit of a bummer, but it happens. Forecasts can change, but right now, leave the board in the car.
