The Lowdown
Alright, Rusty here. Let's talk about what’s happening at Nantasket Beach.
Straight up, the next couple of weeks are looking pretty flat and quiet. There’s a real dry spell coming our way. We’ve got a long gap with hardly any surf to speak of from now right through until mid-August. Honestly, for the first ten days or so of the forecast, it’s a bust. The waves are tiny, barely a ripple, and the energy is weak. The only real glimmer on the horizon is a pulse of swell arriving way out on Friday the 14th of August.
Let’s jump to that. On Friday the 14th of August, we finally see something. In the morning, a 3.6ft NE swell rolls in, but the wind is a cross-onshore from the NE at 12 mph, so it’s going to be choppy and messy. The combined energy is still only moderate at 75, so it’s not a powerhouse. It’s still rated as poor surf. Then, later that same afternoon, the swell builds to 5.2ft from the NE, with a period of 6 seconds and the combined energy jumps to 207. That’s a moderate energy level, but the wind stays a nasty cross-onshore from the NE at 12 mph, creating a choppy, bumpy surface. That 5.2ft is getting into the zone that’s a bit much for beginners, but with the onshore wind, it’s going to be a battle for everyone. The water temp is sitting at 66.2°, which is a bit colder than normal for the time of year, so don't forget the extra rubber.
So, if you’re desperate for a paddle, that Friday afternoon on the 14th is your only real shot, but don’t expect any magic. It’s a long wait for a pretty average offering.

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.
