Alright, Rusty here again. Let me break down what’s coming up for Tenby over the next couple of weeks, but in feet and miles per hour.
First off, it’s a long, quiet stretch to start. The water’s at 65°, which is much warmer than normal for this time of year, so at least it’s not a cold wait.
From Friday the 10th right through until Monday the 20th of July, don’t even bother. Tiny, weak swells and mostly cross-onshore winds mean you’re just watching flat lines. There’s one moment on Monday afternoon the 13th where it goes glassy, but the swell is only 3ft and a super short 4-second period – combined energy is a weak 62, so it's not happening.
The first real hope comes on Tuesday morning the 21st of July. Swell picks up to 5ft from the West, with a period of 6 seconds. The combined energy hits 272 – finally some push! Wind is cross-off from the WNW at 12 mph, keeping the waves clean. Tenby South Beach is a sheltered beginner spot, so grab a longboard and have a fun, mellow session.
Then we get another dry spell until Friday morning the 24th of July. This one has a bit more grunt: 6ft from the SW, period of 7 seconds, combined energy at 274. Cross-off wind from the West at 12 mph will keep it tidy. A touch big for absolute beginners (over 5ft), but fine for intermediate surfers who want some power.
The absolute best of the run is Saturday morning the 25th of July. Swell sits at 5ft from the WSW with a 9-second period, and the combined energy is the highest we see at 320. Winds are cross-off from the WNW at 16 mph, so it’s gonna be clean and fun. The swell direction is a great match for Tenby’s optimum SW angle, and the size is solid without being too heavy.
So, bottom line: a long flat stretch, a small window on the 21st, another lull, then your best bet is Saturday the 25th of July. Save your energy for that morning.
Rusty.
