The Lowdown
Alright, Rusty here, giving you the straight talk on Tenby (South Beach) for the next couple of weeks.
Right out of the gate, it's looking like a long, quiet stretch. We've got a massive gap starting now through the end of July with nothing worth getting wet for. The water is running a notable 66.6°, which is a solid 6° warmer than it usually is this time of year – feels almost tropical!
Our first real chance for a wave comes on Sunday, July 26th. We'll see a pulse of swell, about 3.3ft from the west, but with a short period of only 6 seconds. The combined energy is a weak (77). The wind is offshore from the NW in the morning, giving us clean faces, but with that short period, it's going to be fat and slow. It's not a standout, just the first sign of life. After that, we're back to tiny, weak dribbles through the end of the month.
Then on Saturday, August 1st, we get another little bump. Swell from the WSW, about 3ft, still with that short 6-second period. The energy is low at (68). The wind stays cross-offshore, keeping it tidy, but it's still the same story – small and weak. The rest of the week into early August is more of the same. There are no true standouts in this whole 16-day window.
Let's be real – this whole stretch is a bust for a proper surf. For Tenby, a run of flat, small days like this is pretty normal for this time of year. You might scratch out a few knee-high rollers on that Sunday the 26th or Saturday the 1st if you've got a longboard and a lot of patience, but keep those hopes low. If you're just starting out, the tiny, glassy mornings on the 28th or 30th of July could be fun for a splash.
