The Lowdown

Alright folks, Rusty here. Let's have a good look at what's on the cards for the next couple of weeks. I've gotta be straight with you, it's a pretty bleak picture overall. We're looking at a long stretch of small, weak surf and poor conditions, so don't get too stoked just yet. The whole run is just one break, Coastguard Beach, and it's not looking good.

The forecast starts on Monday, August 24th, with waves a tiny 1 foot coming from the SE with a short 6-second period. The wind is a moderate cross-offshore at 15 mph, so it's clean, but the energy is pathetic, just a 12 (weak energy). The water temperature is about average for the time of year at 69°. Honestly, it's poor surf. This sets the theme for the next week or so.

Tuesday the 25th is more of the same, with a max of 1 foot in the morning, dropping to 0.7 feet in the afternoon, all with short period swells. Winds are moderate. The following days through to the end of August don't get any better. We're looking at daily heights hovering between 0.3 feet and 2 feet. Periods are short, under 9 seconds, and the combined energy stays in the weak range (never hitting triple digits). It's just not worth paddling out.

Now, into early September, things get interesting, but not in a good way. We get some serious swell energy arriving around September 1st. The Tuesday afternoon sees a bump to 2 feet from the ENE with a 14-second period, and the energy jumps to 227 (moderate). But here's the kicker—it's a light cross-onshore wind, so it'll be bumpy. Then things go wild. From Wednesday the 3rd through to the weekend, the swell height hits 4 feet, but the wind turns into a full-on gale. We're talking 34-37 mph winds from the N and NE. The combined energy rockets up to 1243 (very strong) on the 4th, but the wave comment is "poor surf conditions" and it's described as messy. For a beach break like this, that kind of wind just turns it into a washing machine. If you've got a kite, this might be your window, but for a paddle board, it's a write-off.

The last few days, from September 7th onwards, the swell drops back down to 2 feet and 2 feet, but the wind stays onshore and choppy. The conditions just never line up for a decent session. The whole 16-day window is a dud with no standout options. Sorry, crew, but it is what it is. Sometimes the ocean just takes a holiday.

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.
