Tenby (South Beach) Surf Forecast and Surf Report

Right then, let’s have a look at what’s coming up for Tenby (South Beach). I’m not gonna lie, it’s a pretty tough start. We’ve got a solid week or more of tiny, weak waves before anything even starts to look like a surfable wave.

For the first week, from Thursday the 23rd right through to the end of July, it’s pretty much flat. Swell is hanging around 0.3ft to 1ft, with combined energy barely getting into double figures – we’re talking values of 22 and as low as 6 (weak). The swell direction is mostly SW or WSW, but the period is usually short, between 5 and 10 seconds, so there’s barely any push. The wind is often cross-off or light, but with no wave to work with, it’s a write-off. There’s a brief moment on Sunday the 26th where the swell bumps up to 4ft from the W with a period of 7 seconds and combined energy of 155 (moderate), but the wave comment says it all – poor surf conditions. The wind is offshore, but the quality just isn’t there.

The water temperature is 66°, which is a whopping 6° warmer than normal for this time of year. That’s very unusual, so you’ll be in for a warm one if you’re brave enough for a paddle.

Now, the first real standout doesn’t show up until Sunday the 2nd of August. That morning, the swell jumps to 8ft from the WSW, with a period of 8 seconds and combined energy of 639 (strong). The wind is light and cross-off from the NNW, keeping it clean. This is the pick of the entire forecast. It’s a solid, powerful beach break, but at 8ft, it’s getting into the size that’s better for more experienced surfers. The afternoon is a repeat, with a gentle offshore from the NNW.

Monday the 3rd of August is a bit of a beast. The swell hits 10ft from the WSW, with combined energy over 1000 (very strong). That’s big, heavy, and only for experts. The wind is onshore or cross-onshore, which will make it lumpy and tough. Honestly, for a beach break like this, that much power with wind on it is more of a kiteboarding setup than a paddle surf session.

After that, it drops off fast. The 4th of August sees 5ft to 6ft, but the period is short and the energy plummets. The rest of the window into the second week is back to small, weak waves, with the occasional glassy morning but nothing with any real punch.

So, to wrap it up: the first week is a total blank. Don’t even bother. The one standout is Sunday the 2nd of August. Early morning looks best, with that 8ft of clean, powerful WSW swell. It’s a good bet for a proper session, but it’ll be a bit much for beginners. The spot is fairly consistent, but it can get crowded sometimes, so expect company. That’s your window.

Rusty.
