The Lowdown
Alright, I’m not gonna sugar-coat it. We’ve got a long, flat spell ahead. The only spot that’s even in the conversation is the Lighthouse (Point Judith), a reef and point that needs a healthy SSE swell to work. From Friday the 14th all the way through to about Wednesday the 19th of August, it’s tiny dribble. Swell heights barely hitting 0.9 ft, wave energy is a measly 11, and the period is short and feeble. Nothing doing.
There’s a brief pulse on Thursday the 20th of August. The morning shows a bump of 4 ft from the S with glassy conditions. The combined energy climbs to 126, which is moderate. It’s the only time the score even reaches a “1” in the whole window. The water temp is about average for the time of year.
That’s it. Friday the 21st through Saturday the 22nd drops straight back into tiny, messy junk.
Then on Sunday the 23rd of August, a morning pulse of 4 ft from the SSW shows up with a clean cross-offshore breeze from the WSW at 25 km/h (16 mph) and a combined energy of 116. That’s got some push, but the direction is off for the Lighthouse. It’s a cruel near-miss.
After that, it’s back to a long gap of weak, poor surf. Monday the 24th of August morning is glassy but only 2 ft. The next real chance is Friday the 28th of August morning. It’s glassy again, with a 2 ft SE swell and a combined energy of 64. Conditions look clean, but the period is a short 8 seconds, so it’ll be weak and won’t stand you up.
Bottom line: there are two very small windows of clean, rideable surf in 16 days. The potential was there on the 23rd, but the direction let us down. There’s no true standout session on the cards.

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.
