Alright folks, Rusty here. Let’s see what’s on the cards for Tenby (South Beach) over the next couple of weeks. I gotta be straight with you: it’s going to be a pretty quiet run for a while, with a serious dry spell.

The next few days are looking pretty flat. We’ve got tiny 1ft to 2ft waves, mostly from the W and WSW, with periods around 8-10 seconds. The energy is weak, coming in at between 20 and 52 (combined energy of all swells directed here). The wind is mainly cross-off or clean, and on Wednesday morning the 8th, it’s even glassy with a calm wind. But honestly, with those tiny heights, it’s just not worth getting the wetsuit on.

We get a little blip on the 12th of July with a 3ft easterly swell at a shocking 4-second period, but the wind is cross-onshore and choppy – that’s a no-go. The pick of a bad bunch might be the afternoon of the 12th, where a tiny 0.3ft south-west groundswell (21-second period) comes in with glassy conditions, but 0.3ft is literally nothing to ride.

The real wait is on. From now until the 17th of July, there’s no surf to speak of. Hold on until Friday the 17th afternoon. We get a bit of life: a 5ft WSW swell with an 8-second period and a clean, offshore N wind at 9 mph. The energy climbs to 253 (combined energy of all swells directed here) – finally something surfable, but still very ordinary.

Saturday the 18th is where we start to get a little excited. It’s still not huge, but the morning has clean 6ft swell from the SW with a light offshore NW breeze at 3 mph. The afternoon kicks up to 6ft from the SW, energy at 402 (combined energy of all swells directed here), and a moderate offshore NNW wind at 16 mph. That’s going to be clean and hollow. The swell is a bit short period at 8 seconds, but for Tenby, that’s a decent little window.

Now, the standout window is later in the period. If you can hold out, pin Monday the 20th of July on your calendar. The afternoon looks like the true winner. We’re expecting an 8ft WSW swell with an 8-second period, the energy is a solid 816 (combined energy of all swells directed here), and best of all, it’s coming with a clean cross-off W wind at 6 mph. That is proper surf for the area. It’s getting up there in size, so it’s more for experienced surfers, not beginners.

That’s your best shot. A couple of days later, Tuesday the 21st of July afternoon also shows clean 8ft WSW swell with a light offshore WNW wind, so the run of good waves should last a bit. But the 20th is the standout.

Low tide might be an issue on the bigger days, as beach breaks can fatten out on a high, but with that long fetch and a clean wind, Tenby should have some nice lines.

So, be patient. It’s a flat run for nearly two weeks, but the 18th through the 21st of July is where it’s at. Get ready for that Monday the 20th.

Rusty, out.
