Updates in hr min s Forecast update imminent
What’s up, Rusty here, and I’m looking at Nahant Beach for the next couple weeks.
Truth is, it’s a bummer of a forecast. We’ve got a long stretch of flatness and poor conditions right through the whole 16 days. The first real bump doesn’t even come until Tuesday, July 7th, and even that’s messy.
Sunday and Monday, July 5th and 6th, are almost nothing – 0.7ft from the ESE with choppy wind. Don’t bother.
On Tuesday, July 7th, we get a pulse to 6ft from the east, but the period is only 6 seconds – real short and weak. The wind is onshore at 25 km/h, and the combined energy is 264 (moderate), but it’s all rated poor. That’s a big, sloppy day – not for beginners, and not much fun for anyone.
Wednesday, July 8th, drops to 5ft, period 8 seconds, still cross-onshore. Still poor.
Thursday, July 9th, comes in at 3ft, with a light cross-shore wind. Nothing special.
From Friday, July 10th, it just fades away to tiny stuff – 2ft or less. A couple days like Saturday, July 11th, show glassy 2ft from the north, but with a 5-second period, it’s barely a ripple. Energy is only 44 (weak). Even Saturday, July 18th, has glassy 0.3ft from the east with a 14-second period, but it’s too small to break.
There is no standout here. The best I can say is that Thursday afternoon, July 9th, is clean with a cross-off wind, but it’s only 3ft from the east – a longboard day if you’re bored.
Water temp is about 65°F, right around average for the year.
Bottom line: leave the sticks home. If the wind gets cranking, it might be a kite day, but for surfing, it’s a write-off. This area can go quiet, and that’s what we’ve got. Hang tight – things will turn around.
Rusty.

Information about the Nahant Beach Surf forecast
The above surf forecast table for Nahant Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Nahant Beach can be found by selecting the local surf guide option on the grey menu. Our Nahant 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 (Nahant 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 Nahant 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.
