The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s shaping up for Nantasket Beach.
Honestly, it’s a pretty bleak stretch ahead. We’re looking at over a week of flat, poor conditions. The first recommendation doesn’t even pop up until Thursday, 30 July, and even then it’s a bit of a mixed bag. For the first several days, from Saturday, 25 July right through to Wednesday, 29 July, you’re dealing with tiny, weak swell and onshore or cross-onshore winds. The wave energy is low, mostly in the single digits to low 60s, and the surf just isn’t there. It’s a real bust for paddle surfing.
The only real standout, and it’s a conditional one, arrives on Thursday, 30 July. We get a bump in swell from the ENE, pushing up to 8 ft with a short period of 7 seconds. The combined swell energy jumps to a moderate 544 in the morning and 598 in the afternoon. The wind turns cross-offshore from the NNW and WNW, which is a major positive – it’ll clean things up nicely. This is for the more experienced crowd, as that size is pushing into expert territory. It’s a short-period swell, so it’s not going to have that long, drawn-out power, but it’ll be a heavy, thumping shorebreak. Keep in mind this is a beach break, so with that much energy and short period, it could be a bit of a washing machine. The setup might actually look more interesting for kite surfing than a relaxed paddle session.
Following that, Friday, 31 July, drops back down to a more manageable 4 ft with clean offshore winds from the west, but the energy is weak (151) and the surf is only described as ordinary. After that, from 1 August onwards, we’re back to flat, tiny waves and nothing worth chasing.
So, to sum it up: if you’re an expert looking for a punchy challenge, Thursday, 30 July is your only window. For everyone else, it’s a long wait.
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.
