The Lowdown
G'day, Rusty here. Let's be straight with you: it's a tough stretch ahead for Coastguard Beach. Over the next 16 days, there's really only a sniff of something just about surfable right at the very end, and even that's nothing to write home about. For the first two weeks, you're looking at a long, frustrating gap with nothing worth paddling out for.
Let's run through it. From Saturday the 12th of September all the way through to pretty much the end of the following week, it's a write-off. Tiny little wind slop, mostly under 2 ft, with short, weak periods under 8 seconds. The wave energy is pitiful, with readings down around the 10 to 47 mark (weak energy). On top of that, the wind is almost always cross, cross-on, or onshore, making it choppy and messy. There's one brief moment on Thursday the 17th and Friday the 18th where it goes clean with a light cross-offshore breeze, but the swell is barely 2 ft with a 12-second period on the Friday – that long-period groundswell at that size won't even show at a beach break like this. Too much paddle for nothing.
Then we get into a proper gale-force mess from the 22nd through to the 25th. Winds howling 28 to 44 mph, swell bumps up to 3 ft but it's completely blown out and dangerous. Not for surfing.
The only day that even gets a mention is Saturday the 26th of September. The morning shows some hope: a 3 ft swell from the east at 7 seconds, but with a clean, cross-offshore breeze from the north-northwest. Wave energy ticks up to 88 (still weak to moderate). That's about as good as it gets here. The afternoon gets messy again though. Then Sunday the 27th of September morning has a 3 ft east swell with a longer 11-second period and a clean cross-offshore from the southwest. The energy jumps to 254 (moderate). That's the only real window of cleanish, surfable waves across the whole 16 days. But don't kid yourself – this is still "poor surf conditions" by swell standards and the break is exposed to that east swell with a cross-off wind. It'll be a long way from epic.
Given the constant onshore and cross-shore winds, and the small, weak swell for most of it, this setup looks a whole lot more interesting for kite surfing than paddle surfing. The consistent, consistent crowds here are "sometimes" a thing, but honestly, you won't have to worry about anyone else out there with you for 99% of this forecast.
That's the tough news. It's a long blank run for Coastguard Beach. Forecasts can change, but as it stands, keep your board in the car for a while longer.
Rusty.

Information about the Coastguard Beach Surf forecast
The above surf forecast table for Coastguard Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Coastguard Beach can be found by selecting the local surf guide option on the grey menu. Our Coastguard 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 (Coastguard 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 Coastguard 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.
Coastguard Beach is 14 km (9 miles) from Brewster. If you plan a vacation in Massachusetts, look for hotels and other accommodation in Brewster. Brewster has rooms for a wide range of budgets as well as car hire and transport links.
