The Lowdown
Alright, let’s talk surf. I’m Rusty, and I’m looking at a long, dry spell ahead.
Honestly, we’re staring at a dead zone. From now until the morning of Saturday, August 16th, there’s nothing worth talking about. That’s a full week of flat, poor conditions. Tiny swell, bad wind – just leave the board in the car.
The first real chance to get wet comes on the morning of Sunday, August 17th at Lighthouse (Point Judith). We’ve got a 7ft SSW swell rolling in with a period around 8 seconds. The wave energy is strong, coming in at 805. The wind is blowing offshore from the NNW at 15 mph, so it’ll be clean. But at that size, over 6 feet, this is for experienced surfers only. It’s a reef and point break, which should work well with that direction, but just know that crowds can show up sometimes.
After that Sunday morning, it fades fast. Monday, August 18th, the swell drops to 2ft from the south, and it’s just ordinary. The afternoon has a weird 1ft SE swell with a 14-second period – too long and straight for the beach break. Not your day.
Now, if you’re hanging on for something cleaner, check the morning of Thursday, August 21st. It’s tiny, about 2ft from the SE, but the wind is glassy – dead calm. That’s a rare treat for clean, small waves. The water is around 73°F, which is about average for now.
The rest of the second week stays weak. August 22nd and 23rd bring onshore wind and tiny junk. August 24th is the same story: 1ft SE swell, clean but not enough to surf.
The one day that stands out, the only real highlight, is the morning of Sunday, August 17th at Lighthouse. That 7ft SSW swell with clean offshore wind is your best bet. After that, it’s a waiting game.
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.
