The Lowdown

Alright, Rusty here. Let’s have a look at what’s on offer.

Honestly, this is a tough one. Looking at the whole 16-day window for Nantasket Beach, the surf is tiny and the wind is a mess. There’s a real gap at the start with no real waves to recommend. The first few days are just poor, with small, weak swell and cross-onshore junk. It’s not until Wednesday morning, the 29th of July, that we see a bit of a pulse, but it’s still a struggle.

The best chance to get wet, and I’m saying this with a heavy heart, is Wednesday morning, July 29th. The swell picks up to 3 ft from the ESE, with a short period of 6 seconds, so it’s weak, but the combined energy is a meagre 67. The saving grace is the wind is cross-offshore, making it clean. The water temperature is 64°, which is a solid 5° colder than normal for this time of year, so you’ll want a thicker wetsuit. For a brief window, it might be rideable, but don’t expect much.

The rest of the week stays flat and choppy. Thursday morning the 30th sees a 3 ft swell, but it’s from the NE with onshore wind, so it’s a bumpy mess and the energy is still only 90. By Friday the 31st, it’s back to 3 ft but with a pathetic 5-second period. Not worth paddling out for.

After that, from the 1st of August through to the 11th, it’s a desert. Swell heights barely break 2 ft, and the energy readings are mostly in the single digits or low teens. There’s a couple of clean mornings, like the 5th and 6th of August, but with 0.7 ft to 2 ft of swell, there’s nothing to push you down the line. It’s a long, flat run.

This is a classic case of a summer lull. Nantasket Beach is exposed, but without a solid groundswell and with the wind patterns shifting onshore, the setup looks more interesting for kite surfing than paddle surfing during the choppy afternoons. For now, keep the board in the car and wait for the forecasts to change. It tends not to stay this poor for long.

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.
