The Lowdown
Alright folks, Rusty here. Let’s get straight into it for the Lighthouse (Point Judith). This is a reef and point setup, exposed to the swell, and it’s the only game in town for the next couple of weeks.
Right off the bat, we’ve got a long stretch of nothing. From Friday, September 4th, right through until the morning of Thursday, September 10th, the surf is just flat or too junky to bother with. You’re looking at a solid five-day gap with no real waves. The water is sitting at about 69° right now, which feels about normal for this time of year—nothing weird going on there.
So, the first real chance to get wet comes late on Thursday, September 10th. The morning is where it’s at. We’ve got a 7ft swell pushing in from the southwest, and the wind is blowing clean offshore from the WNW. The combined energy is up there at 966 (moderate, but punchy for this place). That’s a solid sized wave for the Lighthouse, probably too much for the beginners, but for the experienced crew, it’s game on. The period is short at 8 seconds, so it’ll be a bit sectiony and bumpy, but with that offshore wind, it’ll be plenty rideable.
The afternoon on the 10th drops off to 5ft, still from the SSW, but the energy is down to 228. The wind holds offshore from the NW, so it stays clean, but it’s a step down in size. You’ll still get a few, but that morning window is the standout.
After that, it’s back to the doldrums. From Friday the 11th right through to the end of the forecast on Saturday the 19th, the swell is tiny, mostly under 3ft, with a mix of cross-shore and onshore winds. There’s a brief moment on Thursday the 17th with glassy conditions and a 2ft ESE swell, but it’s weak with only 37 energy. It’s pretty much a write-off for the second week.
Honestly, if you’re looking to surf, the only real window is the morning of Thursday, September 10th. Set the alarm early. Otherwise, it’s a long wait.
Rusty.

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.
