The Lowdown
Alright, this is Rusty. Let’s get real about Coastguard Beach.
Right now, and for the foreseeable future, there’s just nothing happening here. The entire 16-day window is a tough one for surfers. The finder shows zero recommendations, and the guidance confirms it’s a beginner spot, consistent, but the conditions are just flat-out poor for any rideable waves. We’re looking at a long stretch of almost nothing.
The first few days, starting Thursday the 30th of July, are a write-off. There’s a weak 4ft swell from the NNE, but it’s a short period of 6 seconds, and we’ve got a 30 km/h north wind creating a lumpy cross-chop. The combined energy is only moderate at 200, but the wind is just ruining any chance of a clean wave. The water temp is 69°, which is about normal for this time of year, nothing to write home about.
Friday the 31st sees a drop in swell to 3ft, and by the afternoon, it’s a glassy 1ft, but the wave energy is a measly 58. It’s flat. Saturday and Sunday the 1st and 2nd of August are even worse, with swell heights dropping to 0.3ft and 0.7ft. The combined energy bottoms out at 3 and 7. There’s just no push.
The pattern continues all through the first week of August. We see tiny 1ft and 2ft swells, but the period is short, and the energy is always below 100. The wind is mostly cross-off or clean, but it doesn’t matter when there’s nothing to ride. The 7th of August at least shows a 3ft swell from the south, but it’s got a period of only 4 seconds and a fresh wind, so it’s just messy mush.
The second week doesn’t improve. From the 8th to the 14th of August, it’s the same story: tiny swells, low energy. The 14th of August sees a 4ft swell from the NNE again, with a 6-second period and a choppy cross-onshore wind, but the energy is finally decent at 114. Still, the overall quality is marked as poor, and the wind is bad.
So, the honest truth is there are no standout days. No secret session to get excited about. The only thing close to a “best” option would be the late afternoon of the 31st of July, when the wind goes glassy and the swell is 1ft from the SE with a 9-second period, but even then, the energy is only 58. It’s a flat, clean, and disappointing option.
Given the consistent poor surf conditions, this setup is much more interesting for a kiteboarder than a paddle surfer. It’s a blank run for us, and it’s just how it is here sometimes.

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.
