Nantasket Beach Surf Forecast and Surf Report

Alright folks, Rusty here with the outlook for our local stretch.

Well, I gotta be straight with you—this is a tough one. Looking at the whole 16-day window, there's not a single session that’s worth paddling out for. We’ve got a flat spell that just won’t quit. From now, right through to the end of the month and beyond, every single time slot is flagged as "poor surf conditions." There’s no getting around it; we’re in a dry spell.

Let’s run through it anyway. Starting from Sunday the 16th of August, it’s flat. Really flat. Swell heights are down around 0.3 ft to 1 ft, with combined energy barely getting into double digits—weak readings of just 2 to 39 for most of the first week. There's no push, no power.

For Nantasket Beach, which is an exposed beach break that ideally wants a NE swell, we're seeing mostly weak, short-period ESE and E windswell. The period struggles to get over 9 seconds, and often it’s down around 6 or 7 seconds. That's just junky, short-period slop that won't wrap in or hold up.

A couple of mornings see glassy conditions, like Sunday the 16th morning and Saturday the 22nd morning, but with a swell of only 0.3 ft to 1 ft, it doesn't matter how clean it looks—there's nothing to ride. Mid-week sees some cross-off winds that would clean it up, but again, the swell is too weak.

There’s a tiny blip on Wednesday the 26th of August, where combined energy climbs to 61 and 64, and the period stretches to 14-15 seconds. That's a long period groundswell component, but even then, the height is only 1.0 ft. That energy is spread out and mushy.

Later on, Monday the 31st of August shows the best reading of the whole outlook—2 ft, combined energy of 52, and glassy in the morning. But for a beach break like Nantasket, 2 ft of short period (8 seconds) with an onshore wind kicking up in the afternoon is still poor. It’s simply not enough.

The water temp is sitting around 69°F, pretty much average for this time of year, nothing weird there.

Honestly, with the significant swell being so weak and the setup being a beach, this would be more interesting for a kite surfer than someone with a paddle. The forecasts can change, and it won't stay this flat forever, but right now, keep the boards in the car and save the energy.
