The Lowdown
Alright folks, Rusty here. Let’s be straight with you – the next 16 days at Nantasket Beach are a tough pill to swallow. We’re looking at a long, dry spell with no real surf on offer. The first entry is for the 19th of July, and it’s a dud. From there, we’ve got a solid two-week stretch of flat, weak, and choppy conditions. There’s simply no standout, no window where the stars align. The swell energy is consistently weak, barely cracking triple digits on a couple of afternoons, topping out at a moderate 120 (combined energy of all swells), and even then, the quality is labelled as poor. The wind is often cross or cross-on, ruffling up what little bump there is. If you’re looking to paddle out, you’re better off saving your energy. The water temperature is about average for this time of year, nothing wild to report there. Honestly, this setup looks more interesting for a kite surfer than a traditional surfer, with the wind blowing across the beach and the swell being insignificant. It’s a blank run, and for this area, that’s not totally unusual. Forecasts can change, but as it stands, keep the board in the car.

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.
