The Lowdown
Alright, Rusty here. Let's have a look at what's on the table for the next couple of weeks.
Well, I'm not gonna lie, it’s a grim picture. We've got a solid 16-day window ahead, and frankly, there’s nothing to get excited about. The first real chance of any surf at Tenby (South Beach) doesn't appear until Thursday the 30th of July, and even that is a letdown. There’s a long stretch here where the ocean is just not cooperating.
For the entire forecast period, every single session is tagged as poor surf conditions. The combined energy is weak as a kitten, with most readings well under 100 (34, 7, 2... you get the picture). There’s one reading on Monday the 3rd of August that bumps up to 99, but that’s still barely a pulse. The swell is tiny, never really getting above 3ft, and it's mostly coming from the west or southwest, which isn't what we want at this sheltered spot. The optimum direction for Tenby is SW, so the swell angle is sometimes okay, but there's just no oomph behind it.
The water temp is about average for the time of year, so no surprises in the wetsuit department.
Honestly, the only thing making this even slightly interesting is that there are a few glassy or clean windows. The afternoon of Sunday the 2nd of August looks glassy, but with a piddly 1ft swell. The afternoon of Monday the 10th of August is also glassy, but with a 0.3ft of long-period (13-second) groundswell from the SW. Long period is usually a good sign for energy, but there's none to speak of here; it's just a long time between knee-high sets.
With the swell so small and the energy so low, this is strictly a session for the absolute beginner to practice paddling on a longboard. There’s simply no wave to ride. The consistent onshore and cross-onshore winds later in the run will just mess up what little bump there is. This is a blank period, plain and simple. Things can’t stay this quiet forever, but for now, leave the board in the car.
Rusty.
