The Lowdown
Alright, Rusty here again. Let’s break down the same stretch in feet and miles per hour, ’cause I know some of you think that way.
The bottom line is, Matunuck is in a long, quiet spell. The first real surf to talk about doesn’t come until Monday, August 17th. That morning, we’ve got a 6ft swell from the SSW, with a period of 7 seconds. The combined energy is 293, which is moderate. That’s about 6ft, putting it into expert-only territory—beginners, stay on the sand. The wind is from the west at 9 mph, cross-off, keeping things clean. It’s the biggest pulse of the whole window, and the best bet if you’re desperate for something with a little power.
After that, it drops fast. Tuesday morning the 18th offers 3ft from the S, period 7 seconds, energy down to 95. Wind from the NNE at 6 mph, cross-off, clean. It’s small, but it’s the best of the leftovers. The rest of the week is mostly 1 to 2ft from the S or SSE, with a lot of cross-on or onshore wind. There’s a glassy moment on the morning of the 16th, but the swell is only 2ft—hardly worth the wetsuit.
Water temp is 73°F, which is about 1°F above average for this time of year. Nothing crazy.
The second week, from the 19th on, is just more of the same: tiny swell, weak energy, and mostly choppy or cross-shore winds. The strongest wind comes on the 20th, with a fresh offshore from the NNW at 19 mph, but the swell is only 1ft from the SE. Not worth the paddle.
For kite surfers, the stronger winds on the 19th and 20th might be more interesting than paddling. For the rest of us, it’s a long wait. The 17th is your best shot, and even that’s not a classic. Forecasts can change, but right now, it’s a quiet stretch.
Rusty.

Information about the Matunuck Surf forecast
The above surf forecast table for Matunuck provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Matunuck can be found by selecting the local surf guide option on the grey menu. Our Matunuck 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 (Matunuck) 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 Matunuck 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.
Matunuck is 9 km (6 miles) from Narragansett Pier. If you plan a vacation in Rhode Island, look for hotels and other accommodation in Narragansett Pier. Narragansett Pier has rooms for a wide range of budgets as well as car hire and transport links.
