The Lowdown
Alright folks, Rusty checking in. I’ve looked at the charts for Matunuck, and I gotta be straight with you: it’s a dry run for the next week or more. The swell is flat, the wind is all over the place, and the scores say it all. It’s just one of those summer lulls. But you know how it goes around here – it never stays this bad forever, and a change is always just a forecast away.
The first tiny glimmer comes on the morning of Monday, August 24th. We’re looking at a 1-foot (0.3m) swell from the SE, which is nothing to write home about, but listen to this: the period is a very long 12 seconds, so it’s got that groundswell quality. And the wind? It goes off from the NNW at 3 mph. That’s a light offshore wind, meaning glassy, clean conditions. The combined wave energy is weak (35), so it’s not going to be a blower, but for a sneaky early session on a reef break, you might scratch out a couple of clean ones. Don’t expect much power, but the window is open.
We sit through a few more days of junk, and then we hit the real target. The standout session of this whole 16-day outlook is Thursday afternoon, August 27th. Now we’re talking. A 2-foot (0.5m) SE swell, period of 11 seconds – classic groundswell – and the wind goes glassy. Dead flat. Zero wind. That is a major positive for Matunuck, which will be as smooth as a mirror. The combined wave energy registers at 120, which is the highest we see, and the swell direction is right in the sweet spot for this reef. This is the one. Circle this date. Just know that with that long period, the sets might be a little walled-up at a beach setup, but a reef break like this can turn that into a gem. Crowds are sometimes a thing here, so if the conditions hold, expect company.
After that, the mornings of the 29th and 30th show clean, cross-off winds on tiny ankle-biters, but nothing that’ll light a fire. On the 31st of August, we see a bump to 4 feet (1.1m) from the SW, but with a weak 5-second period, that’s just sloppy windswell – not worth the paddle.
So to wrap it up: the one to chase is that Thursday, August 27th afternoon. Glassy groundswell, the best combo we’ve seen. The rest is a waiting game. Stay tuned, the water might wake up.
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.
