The Lowdown
Alright, folks, it’s Rusty here. Let’s be straight with you: the next couple of weeks are looking pretty bleak for any real surf around the Point Judith Lighthouse (Rhode Island). We’ve got a long dry spell ahead, and it’s going to test your patience.
For the first stretch, from Tuesday through the weekend, it’s a total write-off. We’re talking tiny, weak swells with barely any energy behind them. The combined energy is in the low tens to twenties, which is just about nothing. Water temp is sitting at 73°F, which is pretty much spot on for this time of year. You’d be better off finding a lake to paddle on than trying to get a wave here.
We finally see a little bump of life on Monday the 17th. The swell jumps to 5ft, and the energy reading climbs to a solid 214, which is the first sign of moderate wave energy all week. It’s coming from the SSW, but the wind is a cross-off from the NNE. Still, with a period of only 7 seconds, it’s going to be a short-period, crumbly mess. It’s a marginal call at best, but it’s the only game in town.
After that, it’s back into the doldrums for the rest of the week. A few small pulses here and there, but nothing that will get your heart racing. The energy readings bounce between 87 and 164, but the wave heights just don't get there. The wind stays messy, mostly cross or cross-off.
Now, for you patient ones, there’s a glimmer of hope in the second week. Sunday the 23rd is looking like the standout of the whole period. The swell builds to over 4ft, hitting 4ft in the afternoon, with the combined energy jumping all the way to 278. That’s the strongest energy we’ll see in this whole run. It’s also a clean south swell, and the wind should be light, making for some tidy conditions. This is the one to circle on the calendar.
The swell holds into Monday the 24th, but it drops back a touch. Still, with clean conditions and a moderate cross-off wind, it will be worth a paddle. After that, the window closes again quickly.
So, there you have it. A long, flat, and frustrating outlook, with one promising day a week from Sunday. Don’t hold your breath, but keep an eye on that forecast. The ocean might just surprise us.
Rusty, out.

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.
