The Lowdown
Alright folks, Rusty here. Let's have a look at what Nantasket Beach has got cooking for us over the next couple of weeks. I won't candy-coat it; this is a rough stretch. We've got a 16-day window and, frankly, not a single day with a green light. The pattern is flat and uninspiring, so I'm not pointing to any standout sessions.
The first few days, starting Saturday the 25th of July, we've got tiny 1ft mush from the ESE with a short period of 7 seconds and weak energy (10). Winds are onshore or cross-onshore, making it messy. That sets the tone. On Wednesday afternoon the 29th, swell bumps up to 6ft from the east, energy jumps to 253 (moderate), but the period is a dismal 4 seconds and it's onshore and rainy. The wave comment says "poor surf conditions," and at that size with that wind, it's a washing machine. For a beach break like Nantasket, that's more of a kite surfer's day than a paddle surfer's.
Thursday the 30th sees a 5ft ENE swell with 7-second period and energy hitting 359 (still moderate) but winds are a strong 16 mph from the NNE, creating a nasty cross-chop. Poor conditions again.
After that, it's back to tiny dribble. We get a couple of glassy windows, like Saturday morning August 1st with 2ft and glassy conditions, and Monday morning August 3rd also glassy with a 2ft ESE swell. But the energy is in the teens (20 and 11 respectively), period is short (6 seconds or 4 seconds), so you're looking at knee-high dribble that's clean but barely rideable. The best winds we see are those glassy and cross-off conditions on August 6th and 7th, but again, the swell is 2ft to 2ft with energy only in the 30-45 range.
The water temperature is a notable 63°F, which is about 5° colder than average for this time of year—that's much colder than normal, so you'll want a thick wetsuit.
Honestly, there is no surf to get excited about here. The entire 16-day run is a write-off. For Nantasket Beach, a blank run like this is more normal for the area in summer when we're waiting on a good storm track. The forecasts can change, but as it stands, leave the boards in the car and maybe go for a swim when it's glassy.
Stay patient,
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.

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.
