The Lowdown

Alright, folks, I’m Rusty, and I’ve been watching this stretch of coast like a hawk. The outlook is a bit of a grind, so don’t get your hopes up too early.

For the next two weeks, the surf is going to be a real struggle. We’re looking at a solid gap of nothing worthwhile from the start of the period all the way through to the 20th of September. There’s barely a ripple, and what little shows up is all weak, short-period junk with poor timing. The wind does go glassy and calm at times, especially on the 8th, but there’s simply no swell to work with. It’s a real bummer.

Then, things finally start to look a little more interesting around Monday the 21st of September. That’s where the one true standout of the whole forecast sits. Nantasket Beach gets a pulse of swell from the northeast, pushing about 5 feet, with a period of 6 seconds. The combined energy hits 183 (moderate), which finally gives us something to paddle for. The wind is a clean cross-offshore from the southwest, so the surface will be nice and clean. It’s not a giant day, but after weeks of nothing, it’s a welcome sight. Don’t expect a classic point break peel; it’s a beach break, so the short period means it’ll be a bit soft and lumpy, but it’s rideable. The water temp is about average for the time of year, so no surprises there.

The consistent nature of Nantasket Beach means you’ll find a bank to work with, but you might have some company, as crowds are possible. The swell is a bit over 5 feet, so it might be a touch too much for absolute beginners, but it’s fine for anyone with a bit of time on a board.

Alright, that’s your lot. The first week is a write-off, but keep an eye on the 21st. It’s the only game in town. Until next time, keep your wax fresh.

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.
