The Lowdown
Alright, folks, Rusty here. Let’s get real about the next couple of weeks. We’re looking at a long, dry spell for surf at Lighthouse (Point Judith). This is a reef and point setup, exposed to the SSE, which is the right direction for it. But the swell engine is just not firing.
Right now, the water temp is sitting at 69°, which is pretty much normal for the start of September. We’ve got a tiny bit of energy in the water, but nothing to get excited about.
For the first few days, it’s all small, weak, and messy. Thursday the 3rd and Friday the 4th are just tiny scraps with poor conditions. No real swell to speak of. This continues through the weekend. Honestly, the board is staying in the car.
We do get a pulse of energy around Thursday the 10th of September. The morning shows a 6ft swell from the SSW, with a combined energy of 360 (moderate). That’s the biggest we’ll see, but it’s coming with a strong 19 mph cross-offshore wind from the SW. That’s a lot of breeze for a 6ft wave. It’s going to be bumpy and challenging. The period is only 7 seconds, so it’s a weak, short-period windswell, not a proper groundswell. This is more of a kite-surfing setup than a clean paddle session.
The best chance for a surfable wave comes on Friday the 11th of September. Early morning, we get a 3ft swell from the SSW, with a combined energy of 106 (moderate). The wind is offshore from the NW at 12 mph, which is the best wind of the whole run. The period is still a short 7 seconds, so it won’t be the most powerful, but it will be clean. This is the only day that gets a score of 1 out of 10, and even that is a stretch. It’s the standout, but only because everything else is a goose egg.
After that, the forecast flatlines again. The rest of the second week is tiny, weak, and forgettable, with a few days of promising offshore winds but absolutely no swell to push them. The tiny 0.7ft swell on the 18th with a 12-second period is a tease – it’s a long period, but there’s simply no height to it.
Bottom line: this is a tough 16-day window. The only real chance to get wet is early on the 11th, and even then, keep your expectations on the floor. There’s just no energy in the water.
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.
