The Lowdown
Alright folks, Rusty here. Let’s get straight into it for Nahant Beach.
Well, I gotta be honest with you, the next 16 days are looking pretty grim. We’ve got a long dry spell ahead. There’s no real surf to speak of for the first week or so – just tiny, gutless waves. The first proper chance of anything rideable shows up on Monday, August 17th, but even then it’s nothing to write home about.
The water temp is sitting at about 69.8°, which is pretty normal for this time of year, so no need for a thick wetsuit just yet.
Let’s be real, the standout here is a relative term. The best of a bad bunch looks like Monday, August 17th, and Tuesday, August 18th. On Monday morning, we’ll see a bump up to 2.6ft from the SE, but it’s a short period swell (5 seconds) with a moderate cross-shore wind. The combined energy is weak (46). Monday afternoon gets a little bigger at 3.6ft from the NE, but the wind turns cross-onshore and it gets choppy. Not great.
Tuesday the 18th morning holds a bit of hope with 2.6ft from the ENE, but again, it’s short period (6 seconds) and cross-onshore. The energy is still weak (63). This is a beach break, so with the short period and onshore winds, it’s going to be a close-out city. Honestly, this setup looks more interesting for kite surfing than paddle surfing.
The rest of the period through to the end of August is a continuous run of sub-1.6ft, weak, short-period slop. The winds are a mixed bag – some clean windows, but just nothing to work with. This is one of those blank runs that’s pretty normal for the area when the swell just doesn’t line up. Forecasts can change though, so keep an eye on it.
Stay frothy, but don’t get your hopes up for this one.

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.
