The Lowdown
Alright folks, Rusty here. Let's be straight with you – the next couple of weeks are looking pretty flat and uninspiring for surf. We’ve got a long stretch of small, weak, and disorganized swell, so don’t get your hopes up for anything spectacular. The good news? There are plenty of clean, glassy mornings, so if you’re desperate for a paddle and a few reformy dribbles, you might find something to keep you busy.
The first real window, and honestly the only one that’s even worth mentioning in the first week, is early Tuesday morning, August 4th at Nahant Beach. We’re looking at a tiny 1ft of southeast swell, coming in with a short 7-second period, and combined energy is a weak 24. It’s not going to blow you away, but the wind is light and offshore from the west, making for clean conditions. It’s a beginner-friendly spot anyway, so it could be a fun one for a splash about. However, don't expect much push.
From there, it’s a long, flat grind. The entire rest of the first week and into the second is looking dismal. The swell stays under 1ft, with essentially no energy at all. There’s a glassy morning on Saturday, August 8th (0.3ft, no wind), and again on Sunday, August 9th (0.3ft, light air), but it’s honestly more about floating than surfing. The water temp is running about average for this time of year, so no surprises there.
We finally see a slight bump in the swell around the 18th and 19th of August. The swell jumps up to a mighty 1ft on Tuesday morning, August 18th, with an 8-second period from the ESE. The energy climbs to a moderate-ish 31. It's still not big, but it's the most we’ve seen. Wednesday morning, August 19th, has a bit more offshore wind (SW at 12 mph), which will clean things up, but we’re still only looking at 1ft.
So, bottom line, the next couple of weeks are for the dedicated, the patient, or those who just want to get wet. No standouts, no real power. If you can wait, forecasts can change, but right now it’s a whole lot of nothing. If you see a clean, glassy morning, go for a paddle, but don't expect to be getting barreled. This is 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.
