The Lowdown

Right, folks, Rusty here. Let's have a look at what's cookin' for Nantasket Beach.

Truth be told, we're staring down a long, flat spell. The next decent chance of a wave won't show until Friday the 18th, so that's over a week of small, weak surf. For now, the water's a touch warmer than usual for early September, sittin' around 68°, which is a nice little bonus if you're just going for a swim.

Alright, let's get to the only real highlight on the board. Friday morning, September 18th is your best shot. We'll see a little bump of swell, around 4ft from the NE direction. The combined wave energy is a modest 66, so nothing to write home about, but the wind is forecast to be glass – dead calm. That means the surface will be like a mirror, making up for the small size. It's not a world-beater, but after so many days of nothing, a clean, glassy wave is a beautiful thing. Friday afternoon gets messy with a cross-onshore wind, so make the most of that morning session.

Everything else before that is a write-off. We're talking waves from 0.3ft to 2ft for days on end, with weak energy readings in the single or low double-digits. There's a brief moment on Monday afternoon the 7th with glassy conditions but only 1ft of swell – you'd be paddling more than surfing. The wind does swing offshore a few times, but there's just not enough push to make it worthwhile. The pattern after the 18th doesn't look much better either, with tiny swell and onshore winds creeping back in.

So, there you have it. A long dry spell, broken by one morning of hope. Keep your expectations in check, but if you're desperate for a glide, that Friday morning glass-off is the one to aim for.

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.
