The Lowdown
Alright, let’s break it down. The first week and a half at Westport-The Groins is gonna be a test of patience. This is a sheltered beach/jetty spot, and we’re looking at a long stretch of small, weak swell and cross or cross-onshore winds that’ll keep things sloppy. The combined wave energy is mostly in the low to mid hundreds—weak to moderate, with numbers like 147 and 197 (moderate wave energy) early on, and it doesn’t really get going for a while.
From Monday the 10th through to Saturday the 15th of August, it’s a write-off. Swell heights are stuck around 1ft from the SW, with a few 2ft days, and the wind is either cross or cross-on from the WNW. The period does hit 15 to 20 seconds, which is long-period groundswell, but with no size and choppy conditions, it’s not doing us any favors. The water temperature is about average for this time of year.
We finally get a little glimmer on Sunday the 16th of August. The morning sees a light cross-offshore breeze from the SW, and the swell bumps up to 2ft from the SW with a 16-second period. The combined energy jumps to 319 (moderate wave energy), and it’s clean. This is surfable, but very ordinary. Monday the 17th and Tuesday the 18th keep the same tiny 2ft SW swell, but with clean, offshore winds from the S and SSE. It’s still small, but it’s the best you’ll get in this first stretch.
The standout window, and the only real reason to keep an eye on this spot, is Wednesday the 19th and Thursday the 20th of August. On Wednesday morning, we get a jump to 4ft from the W with an 11-second period, light offshore winds from the SSW, and clean conditions. The combined energy hits 565 (strong wave energy). That’s the best swell of the forecast. The Groins will be offering some proper waves. Thursday morning is even better for conditions: glassy, with 4ft from the W and a 10-second period, and energy at 506 (strong wave energy). This is a true standout for quality. The swell direction is from the W, which matches the optimum swell direction for the break (WSW), so it’s lining up well. The water temp is still about average.
After Thursday the 20th, it drops off fast. Friday the 21st is messy with onshore wind, and the rest of the run into the end of August is back to small, weak SW swell and poor conditions. There’s a tiny glassy window on Saturday the 22nd of August with 2ft from the W, but it’s not enough to get excited about.
So, if you’re paddling out, pencil in the morning of Wednesday the 19th and Thursday the 20th of August for the best bet. The rest is a waiting game.
