The Lowdown
Alright, this is Rusty. Let me tell you what we've got coming.
Right from the start, I’ll be straight with you: surf is going to be a real struggle for most of this outlook. We're looking at a solid run of days with barely anything worth paddling out for. From Wednesday the 19th of August all the way through to Sunday the 23rd, the waves are tiny and the wind is all wrong. You’re looking at knee-high slop at best, with a weak combined energy of just 57. It’s practically flat.
Then we hit Monday the 24th of August, and there's a tiny glimmer. The Lighthouse (Point Judith) finally sees some clean conditions with a light offshore breeze from the WNW. It’s only 3 ft of swell from the south with a poor 6-second period, and the energy is still weak at 62, but it’s the first surfable wave we’ve seen. It’s clean, but it’s not going to set the world on fire. After that, we slide right back into tiny, weak surf for days.
The next genuinely interesting pulse doesn't show up until later. The 27th of August brings a jump in energy, hitting 154 on Thursday morning, with 3 ft of swell from the south. But the wind is a fresh cross-shore at 19 mph, making it lumpy and pretty average. Not a standout, just a step up in size.
Now, if you’re a confident surfer, keep an eye on Friday the 28th of August. We finally get some proper push with 5 ft of swell from the south, combined energy hitting 312 – that’s moderate to strong – and the wind is a cross-offshore, keeping the surface clean. This is the pick of the entire window for experienced surfers only, as it’s a bit too much grunt for beginners. The swell period is still short at 8 seconds, so it’ll be a bit crumbly, but it's the best wave height and energy we see.
After that, the swell fades fast. Saturday and Sunday the 29th and 30th see a drop back to small, weak surf, though Sunday morning looks glassy for the tiny 1 ft leftovers. The very end of the period into September is a write-off with onshore winds and choppy conditions.
Honestly, for the next two and a half weeks, the only real standout is that Friday the 28th. For the rest, it’s going to be a waiting game. The water is sitting at 70°F, which is about average for this time of year, so at least you won’t freeze while you’re waiting.
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.
