The Lowdown
Alright, Rusty here. Let’s look at Nantasket Beach for the next couple of weeks.
To be straight with you, it’s a tough outlook for Nantasket Beach. Over the full 16 days, there’s just nothing worth paddling out for. The swell is tiny, with most days showing a pathetic 0.3ft of height. The energy is dead – the best we see is barely registering a weak 23, and usually it’s down in the single digits. For a beach break like this, you need some real push, and it’s just not there. The period is mostly short and weak, between 3 and 10 seconds, so it’s all messy windswell.
The only tiny flicker of hope is around Saturday the 15th of August. The swell edges up to a very modest 2ft to 2ft from the NE, with a weak 5-second period. The combined energy only hits 23. The wind is cross-off on the Saturday afternoon, so it would be clean. But honestly, calling that a surf is a real stretch. Maybe a longboard float if you’ve got nothing else to do.
Before that, the first week is a total blank. After the 15th, it drops back to flat 0.3ft again. There’s a long gap with zero recommendations. The water temp is running a bit colder than normal for the season, at 66°, so you’ll want a wetsuit even if there was a wave.
Look, this is a bad run for the area, even for a spot that can be consistent. What we’ve got here is more interesting for a kite surfer than a paddle surfer, given the flat water and strong breezes on some days. Keep your gear ready, but don’t hold your breath. Things can change, but right now, I’d call it a washout.
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.
