Alright, I’ll be real with you – Nantasket Beach is flat as a pancake right now. There’s nothing worth paddling out for over this whole 16-day stretch. No surf recommendations, and I mean none. That’s a long dry spell.
Starting Monday the 6th into Tuesday the 7th, it’s tiny. Swell is 0.7 ft to 2 ft, short period, weak energy (8 to 28 combined), and poor winds. Not worth getting wet.
Wednesday the 8th shows a slight bump up to 3 ft to 4 ft, with a 7-second period giving moderate energy (135 and 108), but the cross-onshore wind keeps it choppy. Still poor surf.
Thursday the 9th through Friday the 10th, swell drops to 2 ft to 1 ft, but the wind turns cross-offshore to offshore, so the water cleans up. The water temp is 68°, a touch warmer than normal. Even with clean conditions, the waves are just too small – combined energy down to 16 and 18.
From Saturday the 11th onward, it’s a struggle. Swell never tops 2 ft, period is all over the place, and most of the time the wind is onshore or cross-onshore. There’s a glassy morning on Tuesday the 14th, but with a 0.7 ft swell and 6-second period, it’s like a mirror. Energy at 7 – a joke.
Second week doesn’t bring any relief. From the 15th to the 21st of July, the best we see is 2 ft on Wednesday the 15th with moderate offshore wind, but still flagged as poor surf. The long-range outlook is just as empty.
Bottom line: Nantasket is a no-go for paddle surfing. If you’ve got a kite, the windier afternoons might be fun, but for a surfboard, stay home. These flat spells happen around here sometimes, and it won’t stay this way forever. Forecasts can flip, but right now there’s nothing to ride.

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.
