The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s cookin’ for the next couple of weeks.
Alright, I gotta be straight with you – this is a rough one. The entire 16-day window is looking pretty flat and uninspiring for Nantasket Beach. We’re kicking off on Monday, July 27th, and there’s not a single standout session in the whole forecast. The pattern is the same day after day: tiny waves and poor conditions.
For the first week, from the 27th of July right through to the 2nd of August, we’re stuck with tiny, weak swell. Monday morning shows a mere 2ft from the east with a short period of 6 seconds and a weak combined energy of just 31. The wind is a light cross-onshore, so it’s choppy and messy. The water is much colder than normal for this time of year at 64°, a full 5° below average, which is a real shock to the system. The whole week is a write-off: the swell barely cracks 3ft, and when it does bump up to 5ft on Wednesday the 29th, the wind is howling onshore at 19 mph with heavy rain. The energy climbs to 188, but it’s all wind and rain, no quality.
The second week is even smaller. From the 3rd of August to the 11th of August, we’re looking at ankle-snappers. Swell heights drop to 1.0ft or less, with combined energy values in the single digits. There are a few moments of clean conditions, like on the morning of the 5th of August when it’s glassy, and on the 9th of August when we get a gentle offshore wind, but there’s simply no wave to ride. The swell is just too small to do anything with.
So, the honest truth is there are no good surf options in this 16-day window. Nantasket Beach is a consistent spot, so it tends not to stay this poor for long, but for now, the board stays in the shed. Forecasts can change, but as it stands, this is a blank run.
Stay dry, folks.
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.
