The Lowdown
Alright, let’s talk in feet and miles per hour for you landlocked folks.
It’s a tough start, no sugarcoating it. We’re looking at a long dry spell with nothing worth paddling out for from now until the morning of Sunday, August 9th. That’s a solid 10-day gap of flat or poor conditions.
The one real highlight is the morning of Sunday, the 9th. Make your way to Tenby (South Beach). The swell will be around 6 ft out of the WSW with a period of 8 seconds. The combined energy is 486 (moderate), so there’s some push. The wind is offshore from the WNW at 9 mph, so the waves will be clean and peeling. The water is about 65°F, which is over 4 degrees warmer than average for this time of year – that’s very unusual, feels like a warm bath. This is a beginner-friendly spot, and with the offshore wind, it’ll be a fun morning for learning. It’s a sheltered break, so the size is manageable. Expect some company, but not a circus.
The afternoon sees a little more size at 6 ft, but the wind picks up and gets a bit messier. Monday the 10th has some 4 ft swell with a clean offshore wind in the afternoon, but it’s nothing special.
After that, it’s back to small, weak, or choppy slop. That Sunday morning is your window. Don’t sleep on it.
