The Lowdown

Alright, let's get into it.

Look, straight up, the next couple of weeks are looking pretty flat and ordinary around here. We’ve got a long stretch of tiny, weak swell and iffy winds, so you’re not missing much if you’ve got other plans. There’s a glimmer of hope toward the very end, but we gotta work for it.

For the first week and a half, it's a struggle. From Sunday the 13th to about Friday the 25th of September, it’s mostly waves under 2 ft, with a few small bumps here and there. The combined swell energy is almost always below 100 (weak), and the wind is never really on our side – mostly cross or cross-on, and often moderate to strong. Even the cleaner moments, like Monday afternoon the 14th with a light N cross-off, only gave us 1 ft on a short 8-second period. Not worth paddling out for.

We get a tiny spike on Sunday morning the 20th – 4 ft from the SSW, period 7 seconds, combined energy hitting 146 (moderate). But the catch? That morning it’s cross-shore with a light breeze, and the afternoon cleans up with a SW cross-off. Still, the quality is described as poor. The swell direction is from the SSW, but Lighthouse (Point Judith) is exposed to SSE. That’s not a great match. The waves will be there, but messy and short period. Not the standout.

The real, and I mean only, window of hope shows up on Saturday the 26th of September. Saturday morning brings a clean 2 ft from the SE, with a 9-second period, and we finally get offshore wind out of the W at 15 mph. That’s clean. The combined swell energy is 81 – still moderate – but the conditions are finally working together. This is the best on offer. It's not a big swell, but with offshore wind, Lighthouse should have some clean little lines. The SE swell direction matches the optimum SSE well enough. Expect a few rippable waves. After that, Sunday the 27th morning also looks clean with 2 ft from the SE at 11 seconds, cross-off wind, and combined energy of 99 (moderate). That’s a good follow-up session. But after Monday the 28th, it gets messy again with a cross-onshore 3 ft from the E.

So if you’re hanging for a surf, mark your calendar for the weekend of the 26th and 27th. It’s not a swell of the century, but it’ll be the cleanest you’ll see in this forecast. Before that, don’t bother.

Water temp at the start of the forecast is 69°, which is about normal for this time of year, with a tiny anomaly of 2°. Nothing to write home about.

Stay patient.

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.
