The Lowdown
Alright crew, Rusty here. Let’s break down what’s happening at Coastguard Beach for the next couple of weeks.
Honestly, I’m not going to sugarcoat it – this one’s a bust. The whole 16-day window is looking flat and disappointing. There’s a big gap with no real surf to speak of. We get a little bump on Monday the 3rd of August, but it’s messy and ugly. After that, it’s day after day of tiny, weak waves. The water is 67°, which is a touch colder than usual for this time of year, so you’ll want a decent wetsuit.
The only thing that even comes close to a highlight is that first day. On Monday afternoon, the 3rd of August, we’ve got a 6ft S swell rolling in with a 9-second period. The combined energy is moderate at 537, so there’s some weight behind it. But the wind is howling at 25 mph from the SSW, and it’s a strong cross-off breeze. It’ll be clean-looking, but the quality is just poor. It’s going to be a blown-out mess. For a beginner break, this is too big and too windy. Forget it.
Tuesday morning, the 4th of August, the swell crashes down to a tiny 2ft SSE swell. The wind switches to a light offshore from the west at 6 mph, so the surface will be glassy. But with a combined energy of just 47, you’re looking at knee-high slop at best. It’s clean, but there’s no wave to ride.
From there, it’s a long, flat grind. Wednesday through to the end of the forecast, the swell barely registers. Most days we’re stuck with 0.7ft to 2ft waves and combined energy often below 50. The wind swings around – cross, cross-off, onshore – but it doesn’t matter because there’s no wave to work with. The occasional clean morning, like Thursday the 6th of August with a light offshore, just means you’ll be staring at a flat, glassy ocean.
This is one of those dead runs for the area. It’s normal to have a stretch like this. Forecasts can change, and it won’t stay poor forever, but for now, leave the boards at home. There’s nothing here worth paddling out for.
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.
