The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for Coastguard Beach over the next couple of weeks.
Honestly, it’s a tough outlook. We’re looking at a long stretch of nothing special. The first actual surf recommendation doesn’t pop up until Monday, the 7th of September, and even then it’s a real struggle to get excited. The whole period is dominated by small, weak swell and unfriendly winds.
For the first several days, the energy is just pitiful—combined swell energy bounces between 19 and 37 (weak energy) for most of it. The wind is mostly cross or onshore, making a mess of things. There’s a tiny window on Monday afternoon, the 7th, where things get a little less ugly. The swell is still tiny at 3 ft from the ENE, with a period of 9 seconds, and the combined energy sits at 105 (moderate wave energy). The wind finally goes light and cross-offshore from the NW, and the model says it’s clean. That’s your best bet, but it’s still “surfable waves but very ordinary conditions.” The best of a bad bunch.
After that, it drops right back off. We get a few clean-looking sessions with the wind blowing offshore, but the swell is just too small to do anything with—1 ft or less, not enough to push a log along. There’s a late possibility on the afternoon of the 17th of September: a 2 ft swell from the E with an 8-second period, light offshore wind from the W, and clean conditions. The energy is still only 63 (weak), but it’s glassy and clean. Again, it’s the best of a quiet period.
The water temperature is sitting at 70°F, which is a touch warmer than normal for this time of year. Other than that, there’s no standout. No big swells, no perfect conditions. It’s one of those periods where you just have to wait for the forecasts to change.
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.
