The Lowdown

Alright, this is Rusty, and I’m looking at the 16-day picture for Nantasket Beach. And honestly, I gotta be straight with you – it’s a tough one. The whole 16-day window is a frustrating wait for any real surf. There’s nothing here that’s going to get me out of bed early. The first real shot of any size doesn’t show up until Sunday the 6th, and even then, it’s a mess.

So, through Thursday the 3rd, Friday the 4th, and Saturday the 5th, we’re looking at tiny, weak waves – 1 ft to 3 ft – with poor conditions. The wind is all over the place, mostly onshore or cross-shore, making it choppy and unrideable. That’s a tough three-day gap right off the bat.

Come Sunday morning the 6th, we finally see a pulse of energy. A NE swell pushes in at 5 ft, with a combined energy of 258 (moderate) and a period of just 7 seconds. That’s a short-period, wind-driven swell, and it’s showing up with a strong NNE cross-shore wind at 15 mph. It’s going to be a bumpy, disorganised mess. The afternoon doesn’t get much better – 5 ft but with a direct onshore wind, making it a paddle-fest. Honestly, for a beach break like Nantasket under these conditions, this setup looks more interesting for kite surfing than paddle surfing.

Monday the 7th is the closest thing to a standout, and it’s a weak one. The swell drops to 3 ft, but it’s from the ENE with a period of 10 seconds – a bit more groundswell character. The wind is a light cross-offshore from the NW at 6 mph in the morning, turning to a clean offshore from the W at 3 mph in the afternoon. That’s clean, glassy-ish conditions. The waves will be small and a little slow, but if you’re desperate for a session, the afternoon window is your best bet. The water temp is 68°, which is about normal for this time of year, so no surprises there.

From Tuesday the 8th all the way through to Friday the 18th, it’s back to flatness. Tiny waves under 2 ft, mostly from the east or southeast, with weak energy. The wind is often offshore or cross-offshore, which keeps the water clean, but there’s simply no swell to work with. It’s a long, dry spell.

So, bottom line: there’s no real swell to get excited about. The only “surfable” moment is a small, clean window on the afternoon of Monday the 7th. If you’re a beginner, you might find a few little closeouts, but it’s nothing to write home about. For everyone else, it’s a waiting game. Forecasts can change, but right now, this is a flat spell for Nantasket.

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.
