The Lowdown
Alright, this is Rusty checkin' in from Matunuck. It's a reef setup here, sheltered from the main swell, and it's intermediate-level, very consistent spot. Water temps are sitting right about 73°F, which is pretty normal for this time of year, so nothing freaky going on with the ocean temp.
Let's be straight with you – the next couple of weeks are looking pretty grim. We've got a long stretch of nothing worth paddling out for. From Friday afternoon, August 14th, right through the weekend, we're talking tiny, choppy junk. A few 0.7ft to 1ft waves with short periods, all cross-onshore. It's a write-off. The combined energy is basically zero, with a reading of just 14 on Friday afternoon, and it stays in the single digits and low teens through to Sunday.
Monday the 17th sees a little bump in size, with 5ft coming in by the morning, but it's accompanied by a fresh 35 km/h cross-onshore wind and rain. That's not surfable, that's a washing machine. The energy climbs to 143, but the conditions are horrible. That afternoon, the wind switches to a cross-off from the NNE at 30 km/h, and the swell pushes to 6ft with a combined energy of 422. That's the biggest energy we see in this window, but the wave comment says it all – "poor surf conditions." The swell is short period, onshore directed, and sloppy. It's not the one.
Tuesday morning, August 18th, offers a brief moment of hope. The wind goes light and cross-off from the NNE, and the swell is 4ft from the SE with a period of 7 seconds. The energy is moderate at 143. The comment says "surfable waves but very ordinary conditions" – that's the best we get for the whole fortnight, and it's still a 1 out of 10. It's borderline. After that, it's back to tiny, weak, and choppy.
We have a gap of several days where the combined energy readings are all below 100, and the scores are all zeros. The second week, from the 21st of August onwards, is a total dead zone. The swell drops to 1.0ft to 3ft, but the periods are short and inconsistent. The wind is mostly cross-onshore. There's a cleaner patch on the 21st and 22nd with cross-off winds, but the swell is just too small to do anything with.
The tail end of the window, around the 27th of August, sees a little 2ft swell with an 11-second period, but the energy is weak and the wind is onshore again. Nothing to get excited about.
So, here's the honest truth: there are no standout days in this 16-day outlook. The only mention of "surfable" waves is a one-star morning on Tuesday, August 18th, with a 4ft cross-off swell. If you're desperate, you could poke around on a longboard, but it's not going to be pretty. The combination of tiny swell, poor wind direction, and short period makes this a tough stretch for Matunuck. Even the bigger energy spike on Monday afternoon is just a lumpy mess.
Forget the board for a bit. The cross-onshore winds and lumpy, choppy conditions on days like Monday the 17th and Thursday the 28th would be more interesting for kite surfing than paddle surfing. The rest of the time, it's just flat and clean or flat and choppy.
This is Rusty, signing off. Keep your eyes on the horizon, but don't hold your breath.

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.
