The Lowdown
Alright, folks, Rusty here. Let's be straight with you about the next 16 days. Honestly, we're looking at a pretty bleak stretch overall. The only break that's even on the radar is Coastguard Beach, and even that's a struggle.
The water temperature is sitting at 70°, which is a touch warmer than normal for this time of year. Not a game-changer, but a nice little detail.
The big picture is that we start with a few days of very small, messy surf. The combined energy is weak, in the double digits (43 or less), and the swell is short-period windswell. It's rideable for a beginner on a longboard, but nothing to get excited about. We're basically looking at a surf drought until the first week of September.
Things try to build a little around Thursday, September 3rd. We get a pulse of swell pushing 6 ft, but it's a short-period (6 seconds) SSE windswell, and the wind is a fresh cross-shore creating a lumpy chop. The combined energy hits 218, which is at least moderate, but the conditions are rated poor. It's a no-go for a good session.
We go through another dry spell with nothing but tiny, weak surf until Wednesday, September 9th. That morning, we finally see a glimmer of hope. It's not a standout, but it's the best we've got. The swell is a clean 2 ft from the SE, with a period of 12 seconds – that's a proper groundswell, which is a big positive. The wind is offshore from the west at 12 mph, keeping things clean. The combined energy is 69, still weak, but those better period and wind conditions are a real plus. The waves will be small and clean, surfable for a longboard or a funboard. The report says "surfable waves but very ordinary conditions," which is the most positive note in the entire run.
Then, later that same Wednesday afternoon, the energy jumps massively to 452 (strong) with a 3 ft, 12-second SSE swell. But the wind is a fresh 19 mph cross-offshore from the NW. It's clean, but that wind is strong. It's a short window of potential for a more experienced surfer on a bigger board, but it's a gamble.
After that, we're back into a pattern of small, weak, and often windy surf for the rest of the forecast period. The wind is consistently from the north or north-east, creating choppy, onshore conditions. The last few days are just tiny, periodless slop.
So, is there a highlight? Not really. The Wednesday, September 9th morning session at Coastguard Beach is the only thing that even qualifies as a "maybe." It's a small, clean, offshore window with a bit of real groundswell energy. For a beginner, it's one of the few times the water will be flat and clean. For anyone else, it's a serious low-tide longboard session.
This is a tough run for the area. It's a consistent break, so it tends not to stay this poor for long, but right now, the forecasts are showing a real blank period. Hang tight, check back in a few days.
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.
