The Lowdown
Alright crew, Rusty here. Let’s cut to the chase: Nahant Beach is looking at a solid 16-day stretch of absolutely nothing worth paddling out for.
Starting now on Sunday, July 26th, it’s a bust. We’ve got a tiny 3ft swell from the ESE with a short 7-second period, and an onshore wind. The combined swell energy is weak (62). The water is a cold 63°, which is a full 5° colder than it should be for this time of year – that’s a very unusual chill, so you’ll need a thick suit.
The whole first week is a mess. Monday the 27th through Wednesday the 29th sees the same small, short-period windswell (2–4ft) and onshore or cross-onshore breezes keeping it choppy and unrideable. Thursday the 30th and Friday the 31st see a small bump to 5–6ft from the ENE/NE, with the energy climbing into the moderate range (204–281), but the period is still short (6–7 seconds) and the northeast wind is onshore. It’s just ugly.
The first weekend of August (the 1st and 2nd) drops right back to nothing – 0.9ft to 2ft of slop. Sunday gets a clean cross-offshore breeze, but the wave height is a pathetic 2ft with almost no energy (13–17). You’d be floating on a lake.
The second week is a copy-paste of the first. Tiny 0.6ft to 2ft waves on Monday the 3rd and Tuesday the 4th, and while Monday afternoon turns glassy, there’s no swell to speak of. Wednesday the 5th through the 10th is a mix of tiny, short-period windswell and mostly onshore or cross-onshore winds. The only slightly bigger pulse is on Thursday the 6th and Friday the 7th, with 4ft to 5ft from the ESE, but again, the period is short and the wind is onshore.
For a spot that is consistent, this is a real bummer. The small, weak, short-period swell with constant onshore wind makes this a beach that’s more suited to a rest day than anything else. These long gaps with no surf are normal for this area in this setup. We just have to wait for a change.
Rusty, signing off.

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.
