Alright, this is Rusty comin' at ya from the beach. Let's get into it, and honestly, I gotta be straight with you.
We're looking at a pretty flat spell here at Nantasket Beach. The whole 16-day run, from Monday the 13th of July right through to Tuesday the 28th, is just one big stretch of nothing special. The swell heights are barely a whisper, mostly 0.3 ft to 1.0 ft, and the combined energy is faint, often reading just 3 or 4. There's a little bump of 1 ft on the 19th, but it's short-period, wind-affected junk. Over the next week and a half, there's really no standout session to get excited about. The water is sitting at 69°, which is a touch warmer than normal for this time of year, but that's the only bit of warmth you'll feel.
The winds are mostly offshore or cross-offshore, which is good for the surface, but you can't do much with these tiny waves. On the 28th, you'll see a tiny 0.7 ft ESE swell with a 8-second period, and the wind is a light cross-offshore from the SW. The energy is still weak at 15. It's surfable for a log maybe, but it's not a recommendation. The whole period is just too small. For a fat, open beach like Nantasket, this is a typical flat spell. It won't stay this way forever, forecasts can change, but right now, there's nil to ride.
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.
