The Lowdown
Alright folks, Rusty here. Let's talk about what's on offer for Nantasket Beach over the next couple of weeks.
Right off the bat, I gotta be straight with you: the surf forecast for Nantasket Beach is pretty much a flat spell for the entire 16-day window. The numbers are low, and every single session is flagged as "poor surf conditions." We're looking at a long, quiet stretch. The combined wave energy barely cracks double digits all period, maxing out at a weak 58 (moderate energy) on the 25th of July. That's not exactly gonna get the heart pumping.
We start with nothing on Thursday, July 16th. A tiny 0.3ft easterly windswell with a 15-second period is there, but with 19 mph cross-offshore winds, it's just messy. The water temperature is sitting at 69°, which is about 2° warmer than usual for this time of year – a nice warm anomaly, but it won't help the waves.
The whole first week is a washout. Friday the 17th through to Thursday the 23rd are all the same story: 0.3ft to 3ft of swell, mostly from the east or southeast, with periods all over the place. The bigger bump is a 3ft, 4-second windswell from the south on Saturday afternoon, the 18th, but it's backed by a fresh breeze. It's a beach break, so those short-period, sloppy conditions would be more interesting for the kite surfers than paddle surfers.
The only glimmer of a clean window shows up at the very end of the month. On Thursday, July 30th, the afternoon goes glassy, but the swell is still just 0.3ft from the east. Friday morning, July 31st, also looks glassy with a 0.7ft easterly swell. For a Nantasket regular, this is the best you can hope for: a tiny, clean glass-off. Don't expect any power, but if you just want to sit out there on a log, it might be your only chance.
Overall, it's a grim 16 days for Nantasket. The consistency is there, but it's consistently tiny. For a spot that's exposed to the northeast, we're just not seeing any real push. Sometimes you get a blank run, and this is one of them. Forecasts can change, but right now, it's a long wait for a very small reward.
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.
