The Lowdown

Alright folks, Rusty here. Let’s be straight with you. If you’re looking for a solid session at Coastguard Beach over the next couple of weeks, you’re going to be doing a lot of looking. This stretch is shaping up to be a real flat spell, and honestly, there’s not a single day that gets the nod for a proper surf. It’s a tough run, and we’ll be scratching our heads for a while.

The water is sitting at 71°F, which is a touch warmer than usual for this time of year. That’s about the only thing that’s firing.

We kick things off on Sunday the 9th with a tiny 1ft of southeast swell and a 6-second period. The morning is clean with a light west wind, but there’s just no energy in the water – the combined swell energy is a weak 8. It’s the same story through Monday and Tuesday. We’re talking ankle-biters at best, with the swell barely registering. By Wednesday the 12th, the swell direction swings north for a bit, but it’s still only 1ft and the energy is weak at 10. The wind is cross-off in the morning which will keep it clean, but there’s nothing to ride.

Things get a little more interesting by Thursday the 13th. The swell bumps up to 3ft from the southwest with a period of 5 seconds, and the energy climbs to 39 – still weak, but a bit more push. The morning is clean with a cross-off breeze. It’s not going to be good, but it’s the best of a bad bunch. That’s not saying much.

Then we hit a real lull from the 14th through the 16th. Swell heights drop right back down. We have some glassy moments on Friday afternoon with no wind, but the swell is a pathetic 0.3ft. There’s just nothing to work with.

The first real pulse of energy shows up on Monday the 17th. The swell jumps to 5ft from the south, and the combined energy finally gets into the moderate range at 216. But the period is a short 7 seconds, and the wind is a cross-shore breeze that will chop it up. The comment says poor surf conditions, and I’m inclined to agree. It’s a messy, weak windswell. At that size, it’s also a bit much for the beginners out there. The setup at the beach looks more interesting for kite surfing than paddle surfing, to be honest.

After that, we’re back to small, weak slop. The swell energy dips back into the weak range for most of the following days. We get a little bump to 150 in the energy on the 20th with a 2ft swell, but the wind is cross-shore and the period is a meh 10 seconds. It’s not clean, and it’s not powerful.

As we push into the third week, there’s nothing to get excited about. We see some moderate energy on the 21st with a 3ft swell from the ESE, but a short 5-second period is a complete no-go. It’s just hoping for anything.

The final weekend on the 22nd and 23rd stays small. Saturday is clean but tiny. Sunday the 23rd brings in a strong cross-off wind – near gale force – with a risk of thunderstorms, but the swell is still only 1ft. That’s just frustrating.

So, there you have it. A long, flat washout for the next 16 days. We’ve got a few moments where the ocean looks pretty, but there’s no power behind it. It’s a blank run, which does happen around here. We just have to wait for the ocean to switch back on. Forecasts can change, but right now, I’d be finding something else to do.

Rusty, signing off.

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.
