The Lowdown
Alright folks, it’s Rusty here, and I’ve gotta be straight with you – the next couple of weeks at Nantasket Beach are looking pretty grim. If you’re itching to paddle out, you’re gonna be waiting a while. We’ve got a long, dry spell of poor surf kicking off this whole forecast window.
Starting from Tuesday the 28th of July right through to Sunday the 9th of August, there’s just nothing worth getting wet for. The swell is tiny, the wind is messy, and every single session gets a big fat zero from me. The wave energy is weak, with values like 36 and 31 (combined swell energy) to start, and it only gets sadder from there. Even when the swell bumps up a bit on Thursday the 30th of July with a 5ft NE swell, the period is a short 7 seconds and the wind is cross-shore, making for a choppy mess. That’s a pass.
You’ll see a bit of a tease around the 3rd and 4th of August with some clean or glassy conditions in the morning, but the waves are barely a ripple at 0.7ft. Not even worth the walk down the beach.
Things don’t really perk up until the second week. From Monday the 10th of August onward, we start to see a glimmer of hope. The wind finally swings offshore and cross-offshore, cleaning things up, but the swell is still small—hovering around 1ft to 2ft from the E or ENE with periods around 8 to 9 seconds. The energy stays weak (in the 20s and 30s), so these are strictly longboard or summer funboard days. It’s not gonna fire, but if you’re desperate, the best of the bunch looks to be Wednesday the 12th of August morning with a 1ft E swell, 9-second period, and clean cross-offshore winds (combined swell energy of 31). The crowds are sometimes an issue here, so you might have some company for those tiny waves.
Overall, Nantasket is a consistent spot, but this 16-day run is a dud. Keep your gear in the car and your hopes low. Forecasts can change, but for now, it’s a bust.

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.
