Gather 'round, folks. Rusty here. Let's look at Nantasket Beach, and I gotta be straight with ya – this is one of those outlooks where you might wanna save your wax for another day. The whole 16-day window is a real struggle for surf. Every single record has a score of zero out of ten for surf quality, so we're not looking at any standout sessions. We've got a gap of no decent surf from the start until the very end of the period.
Alright, let's take it day by day. Starting off Sunday, the 5th of July, you've got a tiny 0.7 ft swell wrapping in from the ESE with a period of 10 seconds. Energy is almost nothing at 17 (weak). The wind is a cross-onshore from the ESE at 9 mph, making it choppy. It's poor. That continues into Monday the 6th – same story, a little more wind, still small and choppy.
Tuesday the 7th sees the swell jump up to 6 ft from the east, but with a period of just 6 seconds – that's short-period, crumbly windswell. The combined energy is 214 (moderate), but it's blown out by a strong onshore ENE wind at 16 mph. The wave comment says "poor surf conditions," so this one's a mess – more of a kite-surfing setup than a paddle session, with that wind and chop. Wednesday and Thursday have some cleaner windows, with the wind going cross-off or offshore, but the swell drops right back down to 4 ft or less. On Thursday the 9th, the wind from the SSW at 12 mph is cross-off, so the surface is clean, but there's almost no energy to work with.
Through the second week, from Friday the 10th onward, we see glassy conditions on a few mornings, like Saturday the 11th with NNW wind at 3 mph and glassy surface, and again on Saturday the 18th and Sunday the 19th. But the swell remains tiny, mostly 0.3 ft to 2 ft, with weak energy readings mostly in the single digits. There's one spike of energy on Tuesday the 7th at 262 (moderate), but the conditions were no good. For the rest of the period, the best you can say is it's clean – but flat. The water temp at Nantasket Beach is 66°F which is about average for this time of year.
Look, Nantasket Beach is consistent in its inconsistency here – it's a flat spell. But keep the board handy; forecasts can change, and it tends not to stay this poor for long. Not much to get excited about right now.

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.
