The Lowdown
Alright folks, Rusty here. Let's be straight with you. I've scanned the next 16 days for Nantasket Beach, and honestly, it’s a tough stretch. We’re looking at a whole lot of flat and small conditions. The standout sessions are few and far between, so keep your expectations in check.
The overall pattern is weak, with wave action mostly below 3 feet and often below 2 feet. We start off with a real dud. The first couple of days are poor—Sunday the 2nd brings a tiny 2ft windswell with a short 4-second period and a cross-chop, making it messy. Not worth the paddle. Monday the 3rd is a bit bigger, pushing 3ft, but the winds are cross-offshore and it stays small in the afternoon. Still not great.
The middle of the week settles right down. From Tuesday the 4th all the way through to the following Tuesday the 11th, we’re in a serious lull. Wave heights are generally around 0.5ft. There’s just no energy. The combined swell energy is weak, often with two-digit values like 41 or even single digits like 4 or 6. You can see it clearly in the data (values like 9, 41, 5, 7, 4, 6). It's a long, flat stretch with nothing to offer.
There’s a glimpse of something on the 13th. Thursday morning, the 13th, shows a small 0.5ft bump with a long 14-second period and clean conditions, but it’s still tiny. The afternoon is where it gets interesting, though. We see a rise to 3ft from the ENE. The period is a short 4-seconds, but the wind is cross-offshore, and the combined energy jumps up to 31. It is a small, weak closeout, but it’s the most interesting thing we’ll see. It will be poor surf, but it might be the only thing worth getting wet for.
Late on the 13th and into the 14th, we see a similar pattern: small, short-period ENE swell around 2ft. Friday morning has a risk of thunderstorms and cross-offshore winds, but the afternoon looks cleaner with gentler offshore breezes. This is probably your best bet of the entire window, but it's still far from epic.
After that, it's back to nothing. From the 15th onward, it’s flat again with 0.5ft to 1ft waves and weak energy. The second week is a write-off, with nothing but small, weak surf for Sunday the 16th and Monday the 17th.
So there you have it. A long, flat stretch, one small blip of activity mid-month that’s still poor quality. If you're desperate, keep an eye on the 13th and 14th, but don't hold your breath. The water is running at 64°, which is five degrees colder than normal for this time of year, so the wetsuit is a must.
Stay patient, and check back next week. Things can change.
Rusty.

Information about the Nantasket Beach Surf forecast
The above surf forecast table for Nantasket Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Nantasket Beach can be found by selecting the local surf guide option on the grey menu. Our Nantasket Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Nantasket Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
Nantasket Beach is 8 km (5 miles) from the city of Hingham. If you plan a vacation in Massachusetts, look for hotels and other accommodation in Hingham. Hingham has rooms for a wide range of budgets as well as car hire and transport links.
