Table - best surf conditions forecast for Nantasket Beach over the next 16 days.


Alright folks, Rusty here. Let's be straight with you – the next couple of weeks are looking pretty flat for Nantasket Beach. There's no surf to speak of right now, and we're looking at a long stretch of tiny, weak waves.

We start off Friday, July 10th, with some knee-high slop at best. The swell is coming from the east at 2ft, but with a weak period of 8 seconds and a light cross-onshore breeze, it's messy and unappealing. The energy is pretty pathetic (33). That same story carries through the weekend and into the next week. Saturday and Sunday look even worse, with the swell dropping and the wind staying onshore or cross-onshore, making for choppy, unrideable conditions. We're looking at a solid 5 to 6 days of pure flatness with no real potential.

The water temp is about average for this time of year, so no need to worry about a wetsuit just yet, but you won't need one for surfing because there's nothing to surf.

Towards the middle of the week, we get a few glimmers of hope, but they're cruel. Tuesday morning, July 14th, we have a clean offshore wind from the west, but the swell is a measly 0.3ft. It's like having a perfectly waxed board with no waves. Same story on Wednesday and Thursday morning with glassy conditions and offshore winds, but the swell is absolutely non-existent. On Thursday, July 16th, we get a brief moment of glassy conditions, but the swell is still just 0.3ft. It's a tease.

The second week doesn't offer much relief. The swell remains small, rarely cracking 2ft, and the wind is mostly onshore or cross-onshore. We see a tiny bump on Tuesday, July 21st, with a 3ft SSE swell, but it's coming from a poor direction for Nantasket (optimum is NE), with a short period of 5 seconds, so it'll be a wobbly, close-out mess. The energy is still low (39). Anything over 2ft in size is a no-go for beginners, but honestly, nothing here is worth paddling out for anyway.

The bottom line: there are no good surf options in this 16-day window. The forecast shows a long, flat run. For this area, that's a pretty normal summer pattern. It tends not to stay poor for long, but for now, the board stays in the shed. Unless you're a kite surfer looking for some strong wind on Monday the 20th, there's nothing for the paddle crew.

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.
