The Lowdown

Alright, Rusty here. Let’s talk about Nantasket Beach.

To be straight with you, this forecast is a tough one. We’re looking at a long stretch of days where the waves just aren’t cooperating. The whole 16-day window is a real mixed bag of tiny, weak swell and messy wind, so there are no true standouts.

From now through the first week of September, don’t get your hopes up. The swell is small, mostly under 3 ft, and the period is short on top of that. The wind is often onshore or cross-onshore, making for choppy, poor conditions. There’s one glimmer on Thursday afternoon, September 3rd, when the wind goes offshore from the WSW at 6 mph and we get a clean combo of 3 ft from the ESE at 6 seconds. It’s the only session that’s even surfable, but the energy is weak – just 64 (moderate wave energy) – so it’s really just small, ordinary waves. It’s not a standout, just the best of a bad lot.

We do get a bump around September 6th and 7th, with swell hitting 4 ft to 4 ft from the ENE. The period stretches to 11 seconds on the 7th, which is a proper groundswell. Energy jumps to 168 (strong wave energy) on the Sunday afternoon. But here’s the catch: the wind stays cross-shore or cross-onshore the whole time, and it’s a beach break. At 4 ft with a crosswind, it’s going to be messy and lumpy. Look, for a kite surfer, that setup could be a hoot, but for a paddle surfer it’s more work than it’s worth.

After that, from September 8th onward, it fades right back to tiny anklesnappers with poor wind again. There’s nothing in this window worth planning a session around.

So, what’s the call? If you absolutely need a paddle on Thursday the 3rd, you might get a few clean little runners, but keep the expectations low. Otherwise, this is a classic New England lull. It hurts to say it, but I’d wait for the next system to shake things up. Forecasts change, so don’t write the whole month off yet.

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.
