The Lowdown
Alright, let me have a look at what's coming down the pipe for Matunuck.
Honestly, mate, it's a bit of a tough stretch. The next week or so is looking pretty grim. We’ve got a run of weak, mostly onshore or cross-off junk that just isn't going to produce anything worth paddling out for. From Sunday the 13th right through to around the 19th, you’re looking at a whole lot of nothing. Swell heights are barely scraping 3ft at best, with periods so short they’re not holding any shape, and the wind just won't play ball. That's a solid week of flat, frustrating conditions. The wave energy is weak, sitting in the low double digits to fifties (35 to 56) so there's just no grunt in the water.
We do get a nudge of energy on the morning of Sunday the 20th of September, with the swell bumping up to 6ft from the SW. The energy jumps to a moderate 225, so there's suddenly some life. But here's the kicker—the wind is a moderate cross-onshore breeze at 12 mph, which is going to chop it right up. For a sheltered reef like Matunuck, that’s not ideal. That south-west swell is coming from more of an open window, so it’ll wrap in, but the surface will be a mess. It’s more of a grumpy session than a good one. The breeze eases a bit in the afternoon as the swell drops to 3ft, but it's still cross-onshore. Water temp is sitting around 69°, which is actually pretty normal for this time of year, so you won’t need a winter suit yet.
After that, it’s back to tiny waves and messy wind for a few days. Then things start to look interesting towards the end of the run.
The real standout is shaping up for Friday the 25th of September. The swell builds nicely to 4ft in the morning, pushing up to 5ft by the afternoon, all coming from the ESE. The swell period is a solid 9 seconds, so it’ll have a bit of push. The wave energy gets strong, hitting 367 in the afternoon. Best of all, the wind swings to a clean cross-offshore breeze from the NE at 16 mph. That’s going to scrub the surface and leave it glassy. Even though the swell direction is ESE and the optimum for this reef is SE, it’s close enough to wrap in and produce some lined-up, clean walls. This is the one to point the van at.
Saturday the 26th keeps that energy alive with a bit more size—4ft from the ESE and energy sitting around 339-346. The wind is still NE at 16 mph, but it goes more cross-shore, so expect a little texture on the face. Still very surfable, just not as perfect as Friday.
Sunday the 27th is similar, with 4ft to 4ft of ESE swell and moderate cross-shore breeze. Monday the 28th offers a cleaner morning with a gentle cross-offshore breeze, but the swell is dropping back to 4ft and the energy fading to 181. It’s still a session, but the peak of the run is definitely Friday and Saturday.
So, to keep it real—you’ve got a long wait, then a sloppy day on the 20th, then the real deal arrives on the 25th and 26th. That’s your window. Crowds are always possible at Matunuck, so get in early.

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.
