The Lowdown
Alright folks, Rusty here. Let’s be straight with you – we’re looking at a pretty quiet stretch ahead at Nantasket Beach. The whole 16-day window is a tough one, with nothing that really gets the heart racing. We’ve got a long gap of flat, poor conditions right from the start. The first whiff of anything surfable doesn’t show up until Tuesday morning, September 8th, and even then it’s pretty ordinary.
The first recommendation is on Tuesday morning, September 8th. We’ve got a small 2ft swell from the ENE. The period is a short 9 seconds, so it’s not going to have much punch. The combined swell energy is weak at 61. What saves it is the wind – a light offshore breeze from the WSW. That’ll keep the surface clean. It’s surfable, but you’ll be working for those little waves. Tuesday afternoon fades to 2ft and cross-off wind, not really an improvement.
The next day, Wednesday September 9th, the swell drops further to just 1ft, again with offshore wind in the morning from the WSW. Clean, but tiny. That’s about it for the whole run. The water temp is about average for this time of year, so no surprises there.
The strongest energy shows up on Sunday, September 6th, with a 5ft swell from the NE and a combined energy reading of 227, which is moderate. But the wind is a cross-shore 16 mph from the NNE, ruining any chance of quality. That’s a no-go. Same with Monday the 7th – 4ft to 4ft from the ENE, with energy in the 200s, but the wind is cross-on. Just messy.
After those mid-period days, we fade back into tiny, weak swells. The rest of the forecast is grim – small 1ft, 0.3ft, 1ft waves with onshore or cross-onshore wind. Even the offshore winds in the second week can’t do anything with the lack of swell.
Bottom line: If you’re desperate for a paddle, Tuesday morning September 8th is your best bet for a clean, knee-high wave. But don’t expect much. Honestly, with the consistent lack of quality, you might want to check the kiting conditions if that’s your thing, because for surfboards, Nantasket Beach is a scratch-and-claw mission for the entire outlook.
Until next time,
Rusty.

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.
