The Lowdown
Alright folks, Rusty here. Let's get straight into it for Lighthouse (Point Judith), a reef and point setup.
The water temp is pretty average for this time of year, nothing unusual to report there. But I gotta be straight with ya – this is a tough run. The whole 16-day window is a real mixed bag of tiny, weak, and messy conditions. There's no true standout session, and a whole lot of it is just not worth paddling out for.
Right now, we’ve got nothing. Wednesday is a total write-off with a tiny 0.3ft to 1.0ft swell and cross-shore breezes kicking up a chop. Thursday the 10th is the closest thing to a pulse, with the swell climbing to 5ft to 6ft from the SSW, but with a short period of only 7 seconds. The wind is clean and cross-offshore though. The combined energy hits 330 (moderate), but the score is basically zero. It’s an option, but only just, and it’s not one I’d get excited about. After that, from Friday the 11th all the way through to Tuesday the 24th, it's just a long run of tiny surf, mostly under 3ft, with very weak energy readings (mostly under 100). There's flat spells galore. We get a few glassy moments on Saturday the 12th and Tuesday the 15th, but with only 0.7ft to 2ft on offer, you’re just floating.
There is a little bump on the 20th and 21st with some 4ft to 4ft easterly swell, but the winds are onshore or cross-onshore, making it choppy and poor. By the time we get to the 24th, there’s a long-period 18-second groundswell from the south, but the height is only 2ft and the combined energy is 172 (moderate), so the energy is just not there to make it work.
Honestly, the best recommendation I can give is to keep your gear ready and your expectations low. Thursday morning the 10th is your best bet if you are desperate and the wind holds clean. It’s the only time the swell gets over 5ft, and with that short period, it's not going to be clean or powerful. For the rest, it's a waiting game. This stretch looks like it’s more suited for a kite than a paddle, especially on the 20th when the onshore winds and chop kick in.
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.
