The Lowdown
Well, folks, I gotta be straight with you—this isn't a pretty picture. The next 16 days at Nantasket Beach are shaping up to be a real flat spell. We're looking at a long stretch of tiny, weak waves, if you can even call them that. The combined swell energy barely cracks double digits, mostly hovering between 3 and 18 (weak energy), so there's just no push out there. The water's sitting at 65°F, which is a bit colder than normal for this time of year, so you'll want a decent spring suit.
Starting Saturday, August 1st, we've got near-flat conditions with a 0.7ft swell from the ESE at a 9-second period. The morning has a glassy surface with a light WSW wind, but the afternoon goes cross-shore and choppy. Sunday, August 2nd, is even worse—0.3ft to 1ft of sloppy, short-period junk. The wind is cross-off, but don't let that fool you; there's no wave to ride. Monday, August 3rd, brings some moderate rain and a 1ft swell from the SE, but it's crossed up and messy. Tuesday, the 4th, and Wednesday, the 5th, are more of the same: tiny swells, cross-onshore winds, and glassy patches that are just wasted on flat water. The rest of the first week—Thursday the 6th through Sunday the 9th—stays depressingly small, with swells maxing out at 0.3ft. There are some offshore winds on the 7th and 8th, but again, nothing to ride.
The second week doesn't offer any redemption. From Monday, August 10th, through Sunday, August 16th, we're stuck with the same story: swells between 0.3ft and 3ft, short periods, and mostly cross-onshore or onshore winds. The biggest bump comes on Friday, August 14th, with a 3ft SSE swell at a 5-second period, but that's still tiny and junky, with cross-onshore winds. The combined energy hits 37 (weak) that afternoon, but it's hopeless for surfing.
Honestly, there's not a single standout session here. The whole 16-day window is a write-off. Nantasket Beach is exposed to NE swells, so we'd need a low-pressure system to park itself offshore to get any life. For now, this setup looks more interesting for kite surfing than paddle surfing, given the persistent small waves and light winds. Don't hang up your board just yet—forecasts can change, and a blank run like this is part of the deal around here. But for now, save your energy.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Nantasket Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
