The Lowdown
Alright, folks, Rusty here. Let’s have a look at what’s cookin’ for Nantasket Beach over the next couple of weeks. I gotta be straight with you – it’s a pretty bleak stretch for surf. We’re talking a long, dry run with barely a ripple to get excited about.
Right now and for days to come, Nantasket Beach is flat. The swell energy is next to nothing, with readings like 37, 30, 26 – all weak (less than 100). The water temp is sittin’ around 68°, which is pretty much average for this time of year. No surprises there.
We start on Thursday the 27th of August with tiny 2ft to 1ft easterly slop and short 8 to 9-second periods. The wind is cross-off, but with waves that small, it’s just not worth wettin’ a suit. Friday the 28th is even smaller – 1ft to 1.0ft – with a risk of t-storms, and even though Friday afternoon has a light offshore wind, the swell is just pitiful.
Saturday the 29th and Sunday the 30th are a write-off – we’re talkin’ 2ft to 0.7ft of junk. The whole first week is a bust, and that run of flatness just keeps goin’. Monday the 31st through to Wednesday the 2nd of September has swell staying under 2ft, with energy numbers that barely crack double digits. It's a ghost town out there.
The only flicker of life comes on Wednesday afternoon the 2nd of September, when a 5ft south-easterly swell shows up with a period of just 6 seconds. The combined energy hits 207 (moderate), but the wind is light cross-onshore and it’s a short-period windswell – not exactly gonna set your world on fire. The wave comment says it all: "poor surf conditions."
Thursday the 3rd of September is similar – 3ft to 4ft from the east-northeast, energy around 129 to 172, but it’s onshore and choppy. Still no quality.
Friday the 4th of September morning is the only time that even sniffs at “surfable.” We get 3ft from the east at 8 seconds, and here’s the kicker – glassy conditions. Wind is calm (0 km/h). But the energy is only 90 (weak), and the waves are still just “very ordinary.” That’s the best we get, and it’s barely a whisper.
From there it’s back to flat or tiny, choppy junk for the rest of the run. Saturday the 5th and Sunday the 6th have 3ft to 2ft easterly dribble with moderate cross-onshore winds – choppy and messy. The second week is just more of the same: tiny swell, weak energy, and nothin’ worth paddlin’ out for.
Honestly, there are no standout days here. The only “best on offer” would be Friday morning the 4th of September – glassy, 3ft east swell, but it’s weak and ordinary. If you’re desperate for a splash, that’s your window. For everyone else, this is a solid 16-day gap with no real surf. Forecasts can change, so keep an eye on it, but right now Nantasket Beach is takin’ a nap.

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.
