Alright folks, Rusty here. Let’s be straight with you – we’re looking at a pretty bleak run at Coastguard Beach over the next 16 days. There’s nothing here that gets the heart pumping for a paddle out; the score is a flat zero right through the entire window. We’re talking about a solid two and a half weeks with nothing worth calling surfable.

The first couple of days, the 4th and 5th of July, are just tiny waves. Saturday morning we’ve got a pathetic 0.7 ft from the ESE with a light breeze that’s keeping things clean, but it’s just not enough to ride. The energy is next to nothing (8). Saturday afternoon actually turns glassy, which is a tease – the swell is still a mere 0.7 ft. By Sunday, a strong onshore wind from the east just messes everything up.

We finally see a bit of size pop up on Tuesday the 7th, but it’s a total write-off. We get 6 ft from the ESE with some moderate wave energy (625), but it’s in the middle of heavy rain and a 7-second period that just makes for a lumpy, messy closeout. The afternoon cleans up a touch with a cross-shore wind, but the quality is still poor. This is one to skip.

Wednesday the 8th is where we get our *only* slight glimmer in the whole outlook. The afternoon shows a clean 3 ft from the NE, and the wind is a light cross-offshore. The water temp is sitting at 67°, which is a touch warmer than normal for this time of year by about 3°. But even then, the energy is weak (131) and the period is a short 7 seconds. It’s 'surfable but very ordinary' – and even that feels generous. It’s the closest we get to a recommendation, and it's still not a standout; it's just the least-bad option.

The rest of the run is a desert. From the 9th onward, we see nothing but tiny swell under 3 ft, mostly with weak energy in the teens and single digits. The 13th and 14th of July swing in with some offshore wind, which is a positive sign for clean conditions, but the swell is still only 3 ft to 3 ft. It just never links up. Later in the second week, we see periods jump to 13 seconds on the 18th, which would be a dream at a point break or reef, but here at a beach break like Coastguard, that long period groundswell just won’t bend into shape. Plus the swell height is barely a ripple at 0.3 ft.

Honestly, look elsewhere. The setup here is more interesting for a kite than a surfboard for the next 16 days. Nothing to get excited about.

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.
