The Lowdown
Alright, Rusty here again. Let’s be honest, the next couple of weeks are looking pretty bleak for a proper surf. We've got a whole lot of small, choppy, or flat days ahead. If you're looking for a reason to wax up, you're going to be waiting until the very end of the month for the first real glimmer of hope.
For the stretch starting the 17th through the 28th, it's a total drought. Day in, day out, we're seeing ankle to waist-high slop. The morning of the 18th has a small bump of about 3ft from the south, but it's weak and the conditions are just ordinary. The swell energy is low, around the 80-range (weak). You might catch a fun little longboard wave on the glassy afternoon, but that's about the peak of it.
The rest of that week is just more of the same – tiny 1-2ft waves and messy winds. Even when the wind goes offshore, there's just no swell to groom. This is a classic blank run that's all too common for this stretch of coast, and with few consistent options, you just have to wait it out.
Saturday, August 29th – The One to Watch
Alright, here we go. The real standout of the whole forecast is the afternoon of Saturday, the 29th. The morning still looks a bit rough, with a 4ft south-southeast swell and a light cross-onshore wind. But the afternoon is the ticket. The wind is forecast to go glassy, and we've got a solid 5ft+ swell from the south-southeast with a nice 12-second period. The combined swell energy pushes up to 693 (strong), which is significant energy for this spot.
For Lighthouse (Point Judith) , a reef and point break, this is the time. That long-period swell is going to wrap in and offer some proper, well-shaped waves. It's not huge, but it's got punch, and the glassy conditions will make it as clean as it gets. The water temp is about average for this time of year. This is your window. It's a long-range call, so it's not set in stone, but if the forecast holds, this is the day to be out there.
After that, it fades fast. The 30th and 31st are back to tiny, weak surf, and the first of September is more of the same. If you've got one day to surf in the next two weeks, make it the afternoon of the 29th. It might be a bit of a gamble, but it's the only real bet on the table.
That's all from me. Stay patient.

Information about the Lighthouse Surf forecast
The above surf forecast table for Lighthouse provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Lighthouse can be found by selecting the local surf guide option on the grey menu. Our Lighthouse 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 (Lighthouse) 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 Lighthouse 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.
Lighthouse is 8 km (5 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.
