The Lowdown
Alright, let's have a look at what's on offer for Matunuck over the next couple of weeks.
To be straight with you, folks, it's a tough stretch ahead. We've got a long run of flat and poor conditions kicking things off that's tough to stomach. From today, Wednesday the 12th, right through to Monday the 24th of August, the wave quality is just not happening. There's a sea breeze that messes things up most afternoons, and when the wind is good, the swell is essentially non-existent. It's a solid stretch of days where you're better off doing something else.
Now, it's not all bad news. The calendar flips to Saturday the 22nd of August and we finally see some life. The swell builds to a solid 5.6ft out of the S with a period of 6 seconds. The combined swell energy jumps to a moderate 238, so there's some proper push behind it. The morning looks promising with a clean cross-offshore breeze from the NNE at 9 mph. That sets up a window for some punchy waves here at Matunuck (Rhode Island). The catch? This is a sheltered reef break, and it's very consistent, which is great, but with that amount of energy and a short period, it's going to be a bit lumpy and peaky. This is one for the experienced folks; 5.6ft is getting up there for beginners. It could get crowded, so be prepared to share.
Keep an eye on Sunday the 23rd of August as well. The morning session sees a 4.3ft SSW swell with a 7-second period and light NNE winds that are going glassy. The energy is still moderate at 161. It's smaller than Saturday, but those clean, glassy conditions will make it look a million times better. Those are the moments when Matunuck can really shine. If I had to pick, that Sunday morning is the standout of the whole run—a real chance for some clean, fun waves.
Beyond that, we slip back into small, choppy stuff for the rest of the forecast period. The water temperature is sitting around 72.5°, which is pretty much normal for this time of year, so you won't need a full winter suit just yet.
Hang in there, the end of the drought is in sight.

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.
