The Lowdown
Alright folks, it’s Rusty here. Let’s not beat around the bush: the next two weeks are looking proper flat. We’ve got a long stretch of tiny, gutless waves and the conditions are going to be against us more than they’re for us. There’s no real groundswell on the cards, just a lot of short-period wind slop. You might as well keep the board in the shed.
Right now, Monday morning, we’ve got some ankle-biters at Nantasket Beach, maybe 0.4m of east-northeast swell, but the cross-shore breeze is making it messy. Water temp is reading 19.5°C, which is a bit warmer than usual for this time of year, a small silver lining if you’re just getting wet. The energy is weak, with a combined swell energy of just 41. It’s not doing anything for us. The afternoon might glass off, but the swell is still too small to matter.
The whole week is a washout, honestly. We’re looking at days with waves barely breaking a foot, mostly in the 0.3-1ft range, with periods that aren’t carrying any punch. Tuesday and Wednesday are just mushy and weak. By Thursday the wind swings offshore and cleans things up, but the swell is gone—0.1m is just a ripple on the water. That trend holds through the weekend and into the middle of next week. We see a tiny bump on Monday the 14th afternoon, with a meter of south swell, but with a period of just 5 seconds. That’s just wind chop, not real surf, and the energy jumps to 66, which is still weak. It’ll be a bumpy mess.
So, the long and short of it is this: we’re looking at a solid 16 days with no real rideable surf. There isn't a single standout in this forecast. The only times the ocean might look appealing are those glassy, offshore mornings, but you’ll be paddling on flat water. With that long of a flat spell, it’s easy to get frustrated, but this is more of a lull than a permanent shut down. These stretches of nothing don’t usually last forever. Forecasts can change, so keep a close eye on it, but for now, it’s a no-go.
For the experienced crew, if we do get any bump from those southerly winds, the beach might offer something for the kite gear, but for a paddle, it’s just not worth the effort.
Stay patient. I’ll be watching the charts.

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.
