The Lowdown
Alright crew, Rusty here. Let's dig into this 16-day run. We've only got one spot on the map, the Lighthouse, which is a reef and point break. Let’s be real, the water's running a bit colder than normal for this time of year, so you might want that extra wetsuit.
We’re kicking off with a flat, messy start. Saturday the 1st and Sunday the 2nd are a washout. You're looking at tiny 2 to 2-foot windswell from the south with a short period, and the wind is junk. The combined energy is a measly 52. Not worth paddling out.
Monday the 3rd, we see a spike to a chunky 6 to 7-foot south swell (combined energy of 457 to 639). That’s a lot of water, but the period is short at 7-8 seconds, meaning it’s gonna be a lumpy, powerful mess. Add in a fresh breeze and a risk of thunderstorms, and this is strictly expert territory. For most of us, it’s a hard pass.
Now for the only real highlight. Tuesday morning, August 4th. For a few hours, everything goes right. The wind drops to glassy – dead calm. We’ve got a 5-foot south swell, still a short 8-second period, but with that clean surface, the waves could actually be fun (combined energy of 295). That’s the best call of the whole outlook by a long shot. At 5 feet, it's getting a bit big for beginners though.
After that Tuesday morning window, the outlook goes completely flat. From Tuesday afternoon all through to Sunday the 16th, it’s a brutal stretch. The swell dies to barely 2 to 3 feet, with periods stuck on 6-7 seconds. The wind is mostly a clean cross-off, which is nice, but there’s just no power. The combined readings are stuck in the double digits – weak sauce.
There's a flicker on the 12th with another glassy morning, and on the 16th a Sunday with a light offshore breeze, but the swell is a pathetic 2 feet. At that size, you're just floating around. The longer-range stuff is uncertain, so don’t bet the farm on it.
Bottom line: If you can only surf once this whole window, set your alarm for first light on Tuesday, August 4th at the Lighthouse. That glassy morning and solid 5-foot swell is your only chance at something good. Be on it.
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.
