The Lowdown
Alright folks, Rusty here. Let’s talk about what’s cookin’ at our local patch.
To be straight with you, the next 16 days look pretty grim for paddlin’. We’ve got a long stretch of flat, weak energy and messy conditions. There’s a brief pulse of swell on Thursday the 10th, but it’s short-period junk that’s more of a hassle than a treat. Honestly, if you’re lookin’ for a proper session, you’re gonna be waiting a while.
The first real chance we see is Thursday morning, September 10th at Lighthouse (Point Judith) . We get a bump of 6 ft from the SSW, with a short, choppy period of 7 seconds – so it’s not gonna be pretty. The combined energy hits 321, so there’s some push there, but with moderate cross-off winds from the WSW, it’ll be clean on the face at least. That said, this is a shifty, mushy wave that’s really for experienced locals who know the peak. It's gonna be too big and unruly for beginners. By the afternoon, same size, same story.
After that, things drop right back. Friday the 11th offers knee-high slop around 3 ft from the SSW, with a weak 67 energy reading. It’s surfable but very ordinary. You might get a fun little wave on the morning offshore flow from the NNW, but don’t expect much.
Then we hit a dead zone. From Friday afternoon all the way through the weekend and into the following week, it’s tiny – 0.6 ft to 1 ft – with cross-shore or onshore breezes. Absolutely nothing worth paddling out for. There’s a tiny window on Monday the 14th morning with clean 1 ft swell from the SE, but it’s barely a ripple.
We get a brief tease on Monday, September 21st when a 4 ft SSW swell shows up with 126 combined energy. The wind is clean from the WSW, so it could look okay. But the period is only 6 seconds, so it’s gonna be lumpy, crumbly, and frustrating. It’s a pass for me.
The standout – and I’m using the term loosely – is that Thursday morning, September 10th pulse. It’s the only time we see any real size, and the cross-off wind keeps the surface clean. But with that short period and poor quality score, it’s a last resort for the desperate. Don’t get your hopes up.
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.
