The Lowdown
Alright, let’s talk surf for the Point Judith Lighthouse area over the next sixteen days. I’m Rusty, and I’ll keep it real.
First thing’s first: it’s a rough start. From Monday, August 10th through Saturday, August 16th, we’ve got a solid week of nothing. Poor surf, tiny waves, and messy winds. Swell heights are barely 2 feet to 2 feet, all from the south or south-southwest, with short periods of 4 to 8 seconds. That’s just weak windswell. The winds are all over the place, but it doesn’t matter because there’s no energy. The combined swell energy is weak, mostly in the teens to low sixties. Don’t even bother.
We finally get a pulse on Monday, August 17th. The morning is the best we’ll see. A 5 foot swell from the south-southwest with a 7-second period. The combined energy hits 223 (moderate), which is the strongest of the whole run. The wind is light from the north, making for clean, offshore conditions. That’s your window. The break at Lighthouse (Point Judith) is a reef and point, and with that swell direction (optimum is SSE) and light offshore wind, it’s going to be clean. The water temp is 73°, which is about 1° warmer than normal – pretty average for this time of year. The session won’t be huge, but it’s the only decent one. The afternoon drops off, with the swell down to 4 feet and energy at 176.
After that, it’s back to the doldrums. Tuesday, August 18th brings a tiny 1 foot swell with a very long 15-second period from the southeast. That’s a groundswell, but it’s way too small to do anything useful, and the wind is onshore. The energy is moderate (111 to 155) but the waves are poor.
From the 19th through the 25th of August, it’s all poor surf. Swell heights are mostly under 3 feet, periods are all over the place, and the winds are generally cross-shore or onshore. There’s a bump on Friday the 21st with a 3 foot swell and fresh offshore winds, but the conditions are still rated poor. Saturday the 22nd sees a 4 foot swell from the southeast, but it’s onshore and only 6 seconds – that’s just choppy junk. The energy hits 211, but it’s not worth paddling out.
So, the only real standout is the morning of Monday, August 17th. That’s your one shot. Everything else is a long gap of poor conditions. The crowds at Lighthouse can show up sometimes, so keep an eye out. For beginners, the 5 foot swell might be a bit much, but for the experienced crew, it’s a solid little session.
To keep it short: a long, disappointing stretch from the 10th to the 16th, one decent morning on the 17th, then another long, quiet spell. Not great, but that’s the way it is. Forecasts can change, but for now, the 17th is your best bet.
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.
