The Lowdown
Alright, Rusty here. Let’s talk about what we’ve got for the next couple weeks. To be straight with you, it’s a tough stretch. We’re looking at a long, long gap of poor conditions before anything even starts to look interesting.
We’re starting off with nothing. From now through Thursday the 24th of September, it’s pretty much a write-off. Small, weak swells, periods are short and gutless, and the wind is mostly messy or just wrong. There are a few glassy moments here and there, but the energy just isn’t there – combined swell energy barely hits three digits at best, and mostly sits in the teens or twenties. You’d be chasing ankle-snappers. The one little blip on Sunday the 13th has a bit of height at 3 ft, but it’s from the south with a 5-second period and 22 mph southerly wind and heavy rain. That’s not surfing, that’s just punishment.
The first real flicker of hope doesn’t come until Friday morning, the 25th of September. Lighthouse (Point Judith) finally sees something we can call surfable – still very ordinary, but surfable. Swell runs 3 ft from the ESE with a 9-second period, and the wind is a light cross-off from the NNW at 6 mph. That’ll clean it right up. The combined energy sits at 106, so there’s a bit of life. It’s small, and the break is a reef and point setup, so that longer 9-second period should wrap in okay. Crowds are sometimes an issue here, so you might have some company.
Honestly, that Friday morning is your best bet for the whole outlook. It’s not a standout in the classic sense, but it’s the only window where the wave comment even says “surfable.” After that, it drops right back off. Saturday the 26th has clean conditions but the swell is tiny, and the wind is howling at 25 mph from the southwest, so it’s a no-go for paddling.
To sum it up: there’s a 14-day stretch of basically nothing, then a small, clean window on the morning of the 25th. If you’re desperate for a paddle, that’s your moment. Otherwise, leave the board in the car.

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.
