Table - best surf conditions forecast for Tenby (South Beach) over the next 16 days.
Alright, Rusty here. Let's take a look at what's goin' on down at Tenby (South Beach) for the next couple of weeks.
Well, I'm not gonna sugarcoat it – the first two weeks are a total write-off. The swell is tiny, the energy is flat-out weak, with combined swell energy mostly in the double digits (40-80 range) and it's all marked as “poor surf conditions.” You're lookin' at a long stretch of flat, clean water but not a single wave worth paddlin' for.
The only real light at the end of the tunnel shows up right at the end of the forecast. On Sunday the 26th, the ocean starts wake up. By the morning we see a 6ft swell from the SW, building to 6.6ft in the afternoon. The combined energy climbs to 432 – that's solid, moderate juice. It's still a bit choppy with onshore wind that day, so it's a marginal call.
But hold onto your board for Monday the 27th. That morning it's glassy, with a solid 10ft SW groundswell. The period is a long 9 seconds, so you're gettin' some good shape and power. The combined energy is a massive 1764 – that is serious, heavy energy. The wind swings offshore from the WNW in the afternoon, cleaning it all up. This is big, expert-only surf. 10ft is no joke, so leave the foamies at home. The water temp is about what you'd expect for this time of year.
So, the verdict is a long, flat spell, but a major, powerful pulse hits on that final Monday. It's a one-day wonder, but it's a doozy. Keep your fingers crossed.
