Alright, Rusty here again.
Right now, Nantasket Beach is dead flat – we’re talking 0.7 ft ESE swells with almost no energy. The water temp is running about normal for the time of year. Whole stretch ahead is looking poor for surf. Saturday afternoon (July 4th) goes glassy with a light 5 km/h breeze, but the waves are still too tiny to ride.
Sunday and Monday stay small and choppy. Not worth suiting up.
Tuesday morning (July 7th) has a bump to about 4 ft from the ESE, but with only a 5-second period and a cross-onshore wind at 20 km/h, it’s going to be choppy and messy. Tuesday afternoon gets a little better: 5 ft swell, short period still, but the wind goes cross-shore – still poor quality.
Wednesday (July 8th) brings 3 ft waves with a bit more period (8 seconds), but it stays choppy to onshore. Then from Thursday (July 9th) onward it cleans right up with offshore winds, but the swell drops to barely a foot or less. Clean but flat.
The 16-day window mostly just gives us tiny, weak surf. The one window that might get you wet is Tuesday afternoon (July 7th), but it won't be pretty. This spot usually needs a better swell direction to fire, and we’re not getting it here.
A long, quiet stretch ahead. Don’t expect much.
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.
