The Lowdown
G’day, Rusty here, lookin’ at the home stretch of summer and into early autumn for Nantasket Beach. Let’s be straight with you – the next couple of weeks are looking pretty grim. We’ve got a long, dry spell of tiny, weak surf ahead, and only the last few days of the outlook show any kind of pulse. If you’re desperate for a paddle, you’ll be waitin’ till nearly the end of September.
The water temp is sitting around 66°F, which is about average for this time of year – no surprises there, just your typical late-summer ocean.
The first real standout in the whole 16-day window is the morning of Thursday the 24th of September. We’ve got a 3ft swell rolling in from the east, with a period of 8 seconds and a combined swell energy of 199 – that’s moderate energy, finally enough to push some shape through. The wind is light offshore from the west, so it’ll be clean and lined up. Nantasket Beach is exposed to the northeast, so this east swell will wrap in nicely for the intermediate crew. It’s not a big day, but after so much nothing, it’s the best we’ve got. Crowds are only a *sometimes* thing here, so with a bit of luck, you’ll have some room.
The Friday morning the 25th of September is another option, with a 3ft east-northeast swell, period of 9 seconds, and combined energy of 101. Wind is cross-off from the southwest, keeping it clean. The swell is a touch smaller, but still rideable for the bigger boards.
Apart from that, it’s flat and frustrating. We’ve got a few days with clean glassy conditions on the 11th and 12th of September, but with swell heights of just 0.3ft to 2ft and energy barely hitting double digits, there’s nothing to catch. The 19th of September afternoon shows a 3ft swell and glassy wind, but the combined energy is only 63 and the period is short – very ordinary conditions, as the file says.
So there you have it. If you can wait till that Thursday the 24th, you might snag a few clean waist-high runners. Before that, leave the board in the car.
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.
