The Lowdown
Alright folks, Rusty here. Let’s talk about what’s cooking in our corner of the ocean. Right now, the outlook is pretty slim, so don’t go getting your hopes up for any hero sessions just yet. The first few days are a write-off with hardly any energy to speak of.
We’re looking at Lighthouse (Point Judith) , a reef and point set-up that’s exposed to the swell. The water temp is sitting at 72°, which is about average for this time of year, so no wetsuit drama there.
Sunday the 16th is a total dud with tiny 0.7 ft swell and poor conditions. Monday the 17th and Tuesday the 18th aren’t much better, though Tuesday morning does show a tiny pulse. The swell jumps to 3 ft from the south, and with a 7-second period, wave energy is moderate (106). The wind goes glassy from the NNE at 3 mph – a glassy morning with clean conditions, but honestly, the waves are still very ordinary. The crowd factor is "sometimes" at this spot, so it might be worth a paddle just for the peace and quiet, but don’t expect much.
The rest of that first week (Wednesday 20th through Saturday 24th) is a real struggle. We’re looking at mostly poor surf with swell sizes barely scraping 1 ft to 3 ft. The combined energy is weak, and the winds are all over the place. The only half-decent moment might be Monday afternoon the 24th, where we get a slight bump to 3 ft from the SSW and a clean, gentle offshore from the WNW (9 mph). It’s surfable, but nothing to write home about.
Now, toward the end of the month, things get interesting but a bit tricky. On the 26th of August, we see a long-period groundswell showing up from the SSE (15 seconds) with a combined energy of 105, but the swell height is only 1 ft. For a point break like Lighthouse, that long period could mean some fun, lined-up waves, but the size is just too small to really get going. Then on the 27th, the energy jumps to 194 in the morning and 179 in the afternoon, with a clean cross-off wind from the SW (12 mph). The swell is still small at 2 ft to 3 ft, but the energy is there, suggesting some punchy little waves if you’re on the right board.
The standout? If I had to pick one, I’d say Thursday morning the 27th of August. The swell is 2 ft from the SSE, period 12 seconds, and the combined energy is a solid 194. The wind is clean from the SW (12 mph). It’s still small, but for a point break, that longer period and clean wind should offer the best shape and most fun of the whole window. Don’t expect barrels, but you’ll get some nice little runners.
After that, the final days of August and into the 31st fade back into weak, ordinary surf. So, if you’re itching for a paddle, aim for that Thursday morning session. It’s the only real standout in a pretty flat run.
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.
