The Lowdown

G’day, Rusty here. Look, I’ll be straight with you – the next couple of weeks are looking flat and pretty uninspiring for a paddle. This stretch of coast is copping a real dry spell in the surf department. We’ve got a whole 16-day window ahead but only one break to talk about, and even that’s a tough sell.

Nantasket Beach is the only option on the table, and it’s a consistent spot, which is normally a good sign, but the problem is the swell just isn’t showing up. Right from the get-go on Wednesday the 22nd, we’re looking at tiny 1 ft SE swell with a short 5-second period and weak combined energy (14). Water temp is sitting at 63°, which is a full 5° colder than normal for this time of year – that’s notably chilly, so you’ll want a thick suit. The wind is cross-offshore though, which will keep it clean, but there’s just nothing to ride.

Throughout Thursday the 23rd and into the weekend, the swell stays below 3 ft, with periods all under 8 seconds – that’s pure windswill, no push or shape to it. Winds flip around from onshore to cross-onshore, so it’s choppy and messy on top of being tiny. The combined energy figures are all in the 10 to 37 range, which is weak – there’s nothing happening out there.

We roll into the first week of August and it’s more of the same. The swell barely nudges 2 ft, periods are short, and the energy levels are pitiful. On Thursday the 31st of July there’s a slight bump with 2 ft SE swell and a 9-second period pushing energy to 79 – that’s the highest we see, but it’s still a weak, meagre pulse. The wind is light cross-onshore, so it’s not going to clean up enough to make it worthwhile.

There are a couple of glassy mornings on Thursday the 30th and Friday the 31st of July with 1.0 ft swell and no wind – the surface will be like a mirror, but you’ll be floating. There’s simply no wave to surf.

Overall, there is not a single standout session in this 16-day outlook. The only consistent break here is Nantasket Beach, but with zero surf quality and no meaningful swell, you’re better off waiting for a change in the forecast. Sometimes it stays flat like this in this area, so it’s not a shock, but it is a bummer.

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.
