The Lowdown
Hey folks, Rusty here. Looking at the next 16 days for Nantasket Beach, it’s a pretty lackluster run overall. We’ve got a long dry spell to start, then a brief pulse of size mid‑week, but it’s not a classic. The water is running much colder than normal for this time of year – 63°F with a -5°F anomaly, so bring a thick suit if you’re heading out.
From Thursday 23 July right through to Tuesday 28 July, it’s all small junk. Waves are under 2ft, mostly onshore or cross‑onshore, short period, and the energy barely registers. Not worth paddling out. The best you’ll get is a few 2ft bumps with poor conditions. I’d say save your energy.
Then we finally see something on Wednesday 29 July. The morning brings a 7ft swell from the ENE, period a short 7 seconds, but the combined energy jumps to 678 (moderate‑strong). Wind is light from the north, cross‑shore, so it’ll be a bit lumpy but rideable. This is the standout of the whole forecast – the biggest size and the direction (ENE) is close to the optimum NE. Keep in mind it’s over 5ft, so a bit much for beginners, but intermediates should find some fun. The afternoon drops to 6ft with a cross‑onshore breeze, still okay but less clean.
Thursday 30 July morning is a different story – glassy calm (SW 0 mph) with a tiny 3ft ENE swell, period 6s, energy only 66. Surfable but very ordinary, good for a beginner session if you’re desperate. After that, from Friday 31 July onward it’s back to flatness – waves under 1ft, weak energy, and onshore winds. The rest of the run is a write‑off.
So to sum it up: if you’re an intermediate and don’t mind a short‑period, lumpy 7ft wave, Wednesday 29 July morning is your only real window. Otherwise, it’s a long wait. Stay tuned – forecasts can change. 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.
