The Lowdown
Alright, Rusty here. Let’s break it down.
This is a tough stretch. We’ve got waves coming, but the wind is going to be a real pain in the neck for almost the whole run. The only day that looks like you should actually get wet is a specific window about a week and a half out, but you’ll have to earn it by waiting through a lot of blown-out days.
The first possible surf shows up on Tuesday morning, August 11th. The swell is small, about 4ft from the north, with a period of 9 seconds. The combined wave energy is a weak 218. The wind is light cross-off from the southeast, which means the surface will be clean. But it’s really marginal, even for a beginner-friendly spot like *Barvas (Lewis)*. Not worth the hype.
Wednesday morning, August 12th is a little better. The swell is 4ft from the west-southwest with an 11-second period, and the combined energy is 361. The wind is still cross-off from the south, keeping things clean. You could get a few fun ones, but it’s still small.
Then we hit a bad stretch of strong cross-onshore winds and messy surf through the middle of the month. Friday and Saturday, August 14th and 15th, are a total loss with onshore winds and lumpy conditions.
Here’s the one day to lock in: Sunday morning, August 16th. We finally get a solid pulse of swell. It’s 8ft from the west-southwest with a 9-second period, and the combined wave energy is 962 – solid moderate energy. The wind is light from the southeast, giving us clean, cross-off conditions. This is the best on offer. At 8ft, it’s got some size, so it’s pushing into more experienced territory. The water temp is about 58°F, which is pretty normal for the season.
After that, the wind swings back onshore and the whole thing falls apart again with strong winds through the final week.
So, the call is: wait it out. Sunday the 16th morning is your only real chance for a good session in a mostly windy and messy 16-day outlook.
Rusty.
