The Lowdown
Hey, it's Rusty. I've been pouring over the charts for Nantasket Beach and honestly, there's just nothing doing in the next 16 days. The water's running at 63°, which is a solid 5° colder than normal for this time of year – you'll feel that chill. The break is usually consistent, but this stretch is a total dead zone. The only flicker of something is on Tuesday afternoon, July 28, when a 6ft SE swell pops up with a short 6-second period – that's a weak, junky windswell, and the combined energy hits 259, which is moderate but not enough to overcome the onshore S wind at 9 mph. The wave comment calls it marginal, and honestly, it's a mess. Every other day is tiny, with heights under 3ft, periods under 10 seconds, and either glassy flat spells or cross/onshore slop. There's a lot of glassy mornings but no swell to go with them. The only decent wind setup comes on Friday morning, August 7, with light offshore W wind, but the swell is a pathetic 0.7ft. So yeah, no surf worth paddling out for. The good news is Nantasket usually bounces back, so don't lose hope – forecasts can change. Stay tuned.

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.
