The Lowdown
Alright, folks, Rusty here. Let’s be straight with you – this stretch ain’t one for the history books. We’re looking at a long, drawn-out period of small, weak surf with barely a pulse. There’s nothing on the cards for the first several days that’s worth paddling out for. We’re talking tiny, short-period leftovers that won’t even stand up. Honestly, from now until the middle of next week, you’re better off cleaning the wax off your deck or going for a swim. There’s a big gap of quiet with zero recommendations.
The only time the ocean shows a flicker of life is around Thursday, August 13th. Even then, we’re just talking about a small pulse. Broadhaven South is the only game in town, and it’s an inconsistent little sheltered cove that needs everything to line up. The water’s a touch warmer than normal for this time of year, sitting at 64°, but that’s about the only anomaly.
On the morning of Thursday, August 13th, we get the pick of a pretty weak bunch. A WSW swell pushes up to about 3ft with a 10-second period, and a light NNW offshore breeze will keep the faces reasonably clean. The combined energy is moderate, reading 231, which is the best we’ll see, but let’s be honest – it’s still a marginal day. You’ll get some surfable little waist-high waves, but it’s very ordinary. This spot is sheltered and rarely pumps, so this is about as good as it gets for this outlook.
That little bump fades fast. By Thursday afternoon the wind picks up to a fresh 19 mph offshore, which blows the top off the small swell. From there, we slide right back into the doldrums. The rest of the period is a snooze-fest of tiny, weak swells and inconsistent energy readings that barely crack triple digits. There’s a glassy moment on the afternoon of Friday, August 21st with a 1.0ft leftover, but it’s a cruel tease – not enough push to do anything with.
If you’re a beginner, don’t worry about it being too big – it never gets over 5ft. For everyone else, this is a blank run that’s pretty normal for this area when the swell windows are shut. Forecasts can change, but for now, save your energy.
Rusty.
