Right, grab a coffee and let’s have a proper look at what’s on offer for Nantasket Beach over the next 16 days.

Honestly, I’ve got to be straight with you – it is looking pretty slim for paddle surfing. The whole 16-day window is a flat spell for the most part, with only a brief, dirty bump of energy around the 7th and 8th of July that is not worth getting excited about. There’s a long dry gap from the start until Tuesday morning, 7th July, when we finally see some movement.

Here’s the run-down. From now right up until Monday afternoon, 6th July, it’s tiny. We’re talking ankle-snappers at 0.7 ft from the ESE. The water temp is about average for the time of year, so no surprises there. The wind is mostly light or gentle, so the surface is clean, but it’s just not enough swell to ride. The energy readings are a joke – between 8 and 16 – that’s weak stuff.

Then on Tuesday morning, 7th July, we get a pulse. It jumps to 4 ft from the SE, but it’s junk. The period is only 6 seconds – super short, choppy windswell – and the wind is onshore from the east. The combined energy hits 146 (moderate), but the conditions are described as poor. It’s just an ugly wall of whitewater. That afternoon drops to 3 ft, still messy with a NNE wind. That’s not surf; that’s a washing machine.

Wednesday morning, 8th July, is the closest we get to a “standout” in this run, but it’s a low bar. We’ve got 4 ft from the NE with a 6-second period. The wind is a light cross-onshore from the NE, and the energy is 178 (moderate). For a beach break like Nantasket, that short period NE groundswell will be closing out fast. It might hold a few corners for a strong intermediate, but the crowd profile says ‘sometimes’ crowded, so a local might snag a couple. But for the general surfer? It’s a poor option. By afternoon it’s gone again.

After that, it’s back to flatness. From Thursday, 9th July, right through to the end of the forecast on Saturday, 18th July, the swell barely hits 2 ft, and most days are under 1 ft. The energy readings are in the single digits or low teens. There’s clean conditions at times, with some glassy spells on Saturday afternoon 4th July and again on Wednesday afternoon 15th July, but with 0.3 ft on offer, you’d be better off on a sandbar.

So, the honest word is: put the board away. The setup with the short-period, onshore windswell and low energy just looks more interesting for kite surfing than paddle surfing. For the true standout? There isn’t one. Just a modest, grovelly window on Wednesday morning, 8th July, for the committed locals at Nantasket Beach.

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.
