The Lowdown
Alright, folks. Rusty here. Let’s break down what’s comin’ for the next couple of weeks.
Honestly, the outlook is a real test of patience. There’s a massive, boring gap of flat, useless conditions right at the start. From Tuesday, July 14th, all the way through to Saturday, July 18th, you’re lookin’ at ridiculously small swell – just 0.3 ft of nothing – so don’t even bother. The water is a touch warmer than average for the time of year at 69°, but you won’t feel it sittin’ on the beach.
The first real sign of life isn’t until Sunday, the 19th of July, at Nantasket Beach. The combined swell energy kicks up to a weak 43, with a 3 ft swell from the ENE. The period is a short 5 seconds, so it’ll be a bit lumpy and weak. The wind on Sunday morning is offshore from the W at 12 mph, which will keep it clean. This is honestly the best of a pretty average bunch for the first week. It’s not a standout by any stretch, but it’s surfable. Expect crowds here sometimes.
After that, the energy drops back down into the teens and twenties for the rest of the week through the 26th, with swell heights bouncin’ between 0.7 ft and 2 ft. The wind plays nice sometimes, with some glassy conditions on the 23rd morning and 27th morning, but the swell just isn’t there to back it up. The combined energy stays weak, never breakin’ 40.
The best chance of a decent wave comes almost two weeks out. On Monday, July 27th, we see a small bump. The combined energy reaches 37, with a 2 ft swell from the ESE. The real winner here is the wind: it’s glassy light from the WSW at 3 mph. That’ll make for a clean, tidy surface. It’s still small, but for this stretch, it’s the best we’ve got. The period is a short 8 seconds, so it won’t have much grunt, but for a log or a longboard, it’ll be a fun little session.
So, to wrap it up: the first week is a write-off. The second week offers a couple of mornings with clean conditions and tiny, weak swell. Sunday the 19th morning is the pick of the early days, and Monday the 27th morning is the overall standout for the cleanest, glassiest conditions, even if the waves are small. Don’t expect any barrels.
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.
