The Lowdown
Right then, let’s have a look at what’s on the cards for the next couple of weeks here.
To be straight up with you, mate, this is about as quiet a run as we get. We’re looking at a long gap with nothing worth paddling out for. The first real sniff of anything surfable doesn’t show up until Wednesday the 5th of August. That’s a solid three or four days of flat or near-flat conditions before we get any action.
On Wednesday morning, we do finally get a bit of a pulse at Tenby (South Beach). The swell pushes up to about 5ft from the WSW, but the period is a short 7 seconds, so it’s going to be a bit lumpy and lack any real punch. The combined wave energy is moderate (211). The wind is offshore from the WNW, which is a massive plus, keeping the surface clean. It’s surfable, but it’s only just. The afternoon picks up a touch to 5ft, but the wind swings cross-offshore and gets stronger, making it less appealing. This is a beginner-friendly beach, and 5ft is at the upper limit of what’s comfortable for learning. Water temperature should be about average for the time of year, nothing unusual there.
After that little blip, the forecast goes back into the doldrums. The rest of the week and right into the second week shows nothing but tiny waves and poor surf conditions. You see a few days with clean offshore winds, but the swell heights are a joke—0.7ft, 2ft, nothing with any grunt. Even the longer period swells that roll through on the 8th and 10th are barely registering on the energy scale (15 and 3). There’s just no power behind them.
Honestly, if you’re desperate for a paddle on Wednesday morning, you might get a few crumbly, clean waves on the high tide, but keep your expectations on the floor. Otherwise, this is a two-week write-off. The setup is so small and weak that it’s not even worth considering the kites. It’s just a flat spell.
