Alright folks, Rusty here again. Let’s call it like it is: the outlook for Nantasket Beach over the next 16 days is flat. Dead flat. Not a single session worth paddling out for. The whole window is starved of swell—wave heights barely get above 0.6 ft to 0.7 ft most days, and even when they bump up, the wind kills it.
Water temp is about 66°, normal for the season, but that doesn’t help when there’s no waves.
Starting July 4, we’ve got clean offshore breeze but only 0.6 ft of east swell. It’s a ghost town out there. Then on July 7 and 8, the swell jumps to 5 ft to 6 ft from the east, with short period of 6 to 7 seconds. The combined energy hits 645 (moderate), but it’s blown out by strong onshore winds at 19 to 30 km/h and rain. That kind of messy, choppy combo is better for kite surfers than anyone on a paddle board. It’s lumpy and ugly.
After that, it’s a long drought. From July 9 all the way through July 19, we’re stuck with 0.3 ft to 3 ft waves and mostly onshore or cross-onshore winds. Even on July 17 and 18, when the wind goes glassy or offshore and the period stretches to 13-14 seconds—classic groundswell feel—the height is only 0.3 ft. No energy, no ride. The crowds won’t be a problem because nobody’s out there.
Nantasket can be consistent, but this is one of those summer flat spells. It’s a dry run. Forecasts might shift, but right now, it’s a no-go. Hang loose and wait.
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.
