Alright, grab a coffee, let's have a look at what's coming. To be straight with you, for the next 16 days it's a pretty tough watch for our little stretch here. I've been staring at the numbers and honestly, there's no real green light or standout sessions ahead. We're looking at a long, quiet run with barely a ripple worth getting wet for.

Let's start at the beginning. This Sunday, the 5th of July, is a non-starter. We're talking about tiny 0.7ft slop, cross-shore winds, and a combined wave energy of just 8. It's flat, it's messy, and it's honestly not worth paddling out for. That sets the tone for a classic flat spell.

Monday the 6th and Tuesday the 7th offer a tiny pulse, but it's a waste of energy. Monday sees 1ft of short-period, choppy slop with a moderate breeze ruining any chance of a clean face. Tuesday actually shows a jump to a 4ft swell, but look, the period is a shocking 6 seconds and the wind is a strong 28 mph onshore. It's going to be a complete washing machine, and at 5ft in the afternoon with that wind, it's just ugly. The combined energy hits 196 (moderate) but the quality is zero.

Wednesday the 8th is a bit better in size with a 4ft swell, but the period is still short at 7 seconds and it's choppy. Thursday the 9th cleans up a bit with some cross-offshore winds and a 2ft swell from the east with an 8-second period, but the energy is weak at 58-82. It's surfable for a beginner, but nothing to write home about. Friday the 10th has a tiny clean window with a 1.0ft swell and light offshore winds from the west in the afternoon, but it's ankle-biters.

The rest of the run from the 11th through the 20th is basically a ghost town. We see tiny 0.3ft to 2ft swells, most with weak energy figures in the single digits or low 20s, and winds that are either cross or cross-off. The water temp is sitting at 67°F, which is a touch warmer than normal for this time of year, but you won't even feel it on a day you're not surfing. For a spot like Coastguard Beach (SC, United States) which is exposed and can be consistent, this is a bummer. It’s a beginner-friendly, consistent beach break, but when it's this flat, it's just a sandbox.

You'd have more fun flying a kite than trying to paddle out on these days. The setup is more interesting for the kite crew than us paddle surfers right now.

Bottom line: there is absolutely nothing to recommend in this 16-day window. It's a solid two-week blank. Forecasts can change, but right now, it's a waiting game.

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.
