The Lowdown
Alright, grab a coffee and let's talk Nantasket Beach. It's Rusty.
Look, I'm gonna be straight with you. This 16-day window is a tough one for Nantasket. We've got a long, drawn-out period of near-flat, choppy junk to start. Friday the 24th is a write-off – tiny 1ft cross-onshore slop with poor energy (12). That sets the tone.
We get a solid grind of nothingness through to the end of July. Saturday and Sunday the 25th and 26th offer a bit of knee-high plus swell, but the wind is onshore or cross-onshore, and the period is short at 7 seconds. The energy stays weak (10 to 54). It's messy. That garbage continues right through the week, with winds swinging onshore and a bit of rain mixed in on the 29th.
Then, finally, a glimmer. The only real pulse comes through on Thursday, July 30th. It's not huge, but it's the standout. We get a solid 7ft to 7ft swell from the ENE and NE, with a bit more punch. The energy jumps up (428 to 748). Here's the big catch though: while that's a decent size, the period is a short 7 seconds. That will wall up quick and won't have much push. But, and it's a big but, the wind goes cross-offshore from the NW at 9 mph. That will groom the surface. That's the day to be out. Conditions look clean. At that size, it'll be too much for beginners, you'll want your wetsuit and some experience. Keep in mind the water is running much colder than normal for this time of year, about 3° colder than average.
After that one good day, the plug gets pulled. Friday the 31st drops back to under 3ft with junk wind. From Saturday, August 1st, we're into a full-on flat spell. A few tiny pulses roll through, but we're talking less than 1ft if you're lucky. The winds are calm or even glassy on the 1st and 5th, but there's nothing to ride. That flat stretch runs all the way to the end of the forecast on August 8th. So, you're looking at about nine days of nothing after that Thursday pulse.
Overall, your window is the 30th of July. That Thursday afternoon with the clean 7ft NE swell is your best bet. Otherwise, it's a long wait. Even if the spot is consistent, the ocean just isn't delivering for paddle surfing here.
Rusty.

A general guide to surfing at Nantasket Beach can be found by selecting the local surf guide option on the grey menu.

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.
