The Lowdown
Alright, Rusty here. Let’s get into the outlook.
First up, I gotta be straight with you – for the next 16 days, it’s a flat spell all the way. Starting from now, right through until August 12th, there’s nothing on offer for surf at Southwick Beach State Park. The swell numbers are zeros across the board, and the wave comment says “poor surf conditions” for every single record in that period. Not a single bump, no swell height, no period, no energy. Zilch.
We’re looking at a full 16-day gap with no recommendations. The water temp is running at 73°F with a 4°F positive anomaly, so it’s a touch warmer than usual for this time of year. That’s notable, but with no surf, it’s just a nice temperature for a swim.
There are some clean wind windows – like Friday morning July 31st with glassy conditions from the WSW, and a few morning windows with offshore or cross-off breezes – but without any swell pushing in, it’s just flat ocean. A couple of mornings on August 3rd and August 9th show gentle offshore winds and clean conditions, but still no wave energy to work with.
Since the break is exposed to swell and the optimum direction is WSW, those clean offshore days would have been promising if there was any groundswell. But there isn’t. For a beach break like this, a long period swell from the optimum direction would have been a treat, but we’re skunked.
Honestly mate, this looks more like a stretch for sunbaking or a paddleboard cruise than for surfing. Given the lack of swell, the setup here might interest kite surfers more than paddle surfers on the few breezier afternoons, but the winds aren’t strong enough for that either.
It’s a blank run, plain and simple. For this area, a run like this is normal when there’s no swell in the forecast. Forecasts can change, but as it stands, don’t bother waxing up.
Rusty.
