The Lowdown
Alright, surfers, Rusty here. Let’s get into it. We’re looking at Tenby (South Beach) for the next couple of weeks, and if I’m being honest, it’s a bit of a slow start. The water’s sitting at 66° which is way warmer than usual for this time of year – a good 5° warmer, which is a bit of a wild one for July.
The first few days are a real struggle. Wednesday the 22nd and Thursday the 23rd are offering next to nothing, with tiny 0.3 ft swells. It’s basically flat, so don’t even bother waxing up. Friday the 24th is the same story with the swell – a piddly 0.3 ft – but the wind goes glassy on the morning. It’s a beautiful morning for a paddle, but there’s nothing to ride.
We’ve got a gap of flat days stretching from Wednesday all the way through to Saturday morning. Then, things finally start to wake up on Sunday the 26th. The swell jumps up to 5 ft from the west, with a short period of 7 seconds. The combined energy hits 197 (moderate), but the wind is cracking offshore from the NW. It’s not perfect, but it’s the first real sign of life. Monday the 27th drops back to 3 ft, and the energy fades to 59 (weak), so that’s a one-day wonder.
The real standout, the one to circle on the calendar, is Saturday the 1st of August. We’ve got a solid 4 ft of swell from the WSW with a period of 9 seconds – that’s a proper groundswell that’ll have some push. The combined energy is strong at 254 (moderate), and the wind is cross-offshore from the W and WSW all day, keeping things clean. This is the best on offer. The wave direction matches the optimum for Tenby, so it should line up nicely. The crowds can be here sometimes, but with conditions like this, it’ll be worth sharing the water.
That Sunday the 2nd of August holds potential with a 5 ft swell from the WSW, but the wind swings cross-onshore from the SSE, which will mess up that shape pretty quickly. The energy is still strong at 300, but it’ll be choppy. After that, Monday the 3rd and Tuesday the 4th see the swell push up to 5 ft and 5 ft, but the wind is straight onshore, making it a messy, blown-out affair. The energy is strong (429 and 366 respectively), but it’s not going to be a fun paddle. The sets will be short period and sloppy, so this might be more interesting for the kite surfers than a traditional paddle session.
The second week fades out with smaller, onshore wind slop, so that Saturday the 1st of August is the one to aim for. It’s a few weeks out, so keep an eye on the forecast, but it’s the only real chance for a decent wave in this window.
Rusty.
