Alright, I'm gonna give you the same story in feet and miles per hour, mate.
Let me tell you about the coming weeks at Tenby (South Beach). Honestly, it’s a bit of a tough stretch for waves. The immediate outlook is pretty flat, with small, weak energy and poor conditions. The water is much warmer than normal for this time of year, sitting at 64°.
Right now, and for the first several days, there’s just not much to get excited about. Swell is tiny, mostly around 1ft from the southwest or west, with weak energy (30 to 42). The wind is constantly cross-off or glassy, so it would be clean, but there’s simply no power to the waves. It’s a great time for a paddle or a swim, but not for surfing. This flat spell runs from the start all the way through the middle of the month.
We do see a little bump in the combined energy around the 18th and 19th of July, with swell picking up to 4ft from the west-southwest. The energy jumps into the moderate range (135 to 157), but the wind turns onshore, so it’s going to be messy. Not worth the drive for a beginner-friendly, sheltered spot like this.
The only real promising window pops up right at the end of the forecast, on the 20th of July. The swell builds to 6ft to 6ft from the west, with moderate energy (295 to 359). The wind is light and cross-shore, so it’ll be a bit textured but workable. This is more than 5ft, so it’s getting a bit too big for absolute beginners, but for a solid intermediate, it could be the best shot of the whole 16 days. Still, with the cross-shore wind and a 7-second period, it won’t be a classic.
Given the long run of flat, clean conditions bookended by a messy wind swell, this setup actually looks more interesting for kite surfing than paddle surfing on the days with more wind and chop. But for a surfer, there’s a single, late-arriving window that’s just okay.
