The Lowdown
Alright folks, Rusty here. Let's have a look at the surf outlook for Lighthouse (Point Judithlighthouse). Straight up, I gotta be honest with you – this is a tough one for the next 16 days. We're looking at a real dry spell, a proper flat spell that stretches from now all the way through to the 16th of September. There's barely a ripple to get excited about for nearly two weeks, and that's a long time to be staring at a flat ocean. The combined wave energy is in the doldrums, barely cracking triple digits for most of that period, with readings like 24, 14, and 6 – it's weak, it's tiny, and it's not worth paddling out for.
The water temp is sitting at 69°F with a positive anomaly of 0.7°F, so it's about average for this time of year at Lighthouse – not a shocker, just standard late-summer warmth.
Now, the only real blip of interest comes on the morning of Thursday, 10th September. We see a bit of a pulse of swell push through, with a combined energy of 365 – that's a moderate wave energy. The swell height jumps to 6ft, coming from the SSW, but the period is a short 7 seconds. That's a windswell, not a proper groundswell. It's going to be messy and lack any real power. Even then, the wind is a cross-off from the SW at 19 mph, which is a fresh breeze. It's gonna be clean, but it's choppy, and the quality is described as poor. For an intermediate spot like Lighthouse, a 6ft swell with a short period and that much wind is just not going to line up well. It's not a standout.
After that, things get interesting in a bad way around the 17th and 18th of September. We see a bigger swell, over 7ft, coming from the ENE and E. The combined energy hits 416 on the 17th morning, which is strong wave energy. But the wind is a moderate cross-onshore from the ENE at 12-16 mph, and it's described as choppy. A 7ft ENE swell with a 7-second period and onshore wind is a total mess. For a reef and point break that's exposed to the SSE, that swell direction is coming from a bad angle anyway. This setup is more interesting for kite surfing than paddle surfing, honestly. The conditions are poor, the crowd factor is a "sometimes" here, but with this kind of junk, it won't matter.
So, to sum it up: there's not a single day in the 16-day window I'd call a true standout. The 10th of September is the only date with any size, but it's a windswell with too much wind. The rest is a flat, drawn-out lull. It's a tough run for the area, but keep the faith – forecasts can shift, and it tends not to stay this poor for long.
Rusty, signing off.

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.
