The Lowdown

Alright folks, Rusty here. Let’s have a proper look at what’s coming down the line for our local waves at Lighthouse (Point Judith) .

Straight up, I’m not gonna sugarcoat it—this 16-day window is a tough one. We’ve got a long stretch of flat, weak, or just plain messy conditions to get through. The first real chance of anything that even looks like a surf comes way down the track. For almost the entire first two weeks, we’re dealing with tiny, short-period slop and angry cross-offshore winds. Don’t get your hopes up.

The story starts on Wednesday, 5 August afternoon: a tiny 2ft S swell at 7 seconds, with cross-off winds. The combined energy is pitiful at 57 – that’s barely a ripple. That theme carries on day after day. Thursday, Friday, Saturday, Sunday... all we get is knee-to-waist-high slop (2ft to 4ft) from the SSW, with periods stuck around 6 to 7 seconds. The wind is mostly a moderate cross-off, which keeps the surface clean-ish, but there’s just no power whatsoever. The best we see in that first week is a combined energy of 104 on Sunday afternoon – still just moderate at best. Honestly, it looks more like a day for a paddle on a longboard than a proper surf.

We do get a little bit of a silver lining on Monday, 11 August morning – the wind goes glassy from the NE, but the swell has dropped to an embarrassing 0.3ft. That’s not even a ripple. The crowd situation at Lighthouse can be "sometimes" busy, but with nothing showing, it’ll be a ghost town.

The second week is more of the same. Small swells and mostly cross-off or cross winds. The water temp at the start of the period was a pleasant 70°F, which is about normal for this time of year. But that won’t help the surf. The only moment that even raises an eyebrow is Thursday, 20 August morning. Swell jumps to 5ft from the SSW, period 7 seconds, with a moderate cross-offshore wind. The combined energy comes in at 281 – that’s actually moderate to strong energy. For a second, it looks like something might happen. But the rating is marginal, and it’s still short-period windswell. By the afternoon, the wind switches to a messy cross-shore and the waves drop to 5ft with a chop. For the groms and beginners, that 5ft swell is pushing the limits – definitely not a learner day. For the experienced crew, it’s the best we’ve got, but don’t expect perfection.

The Best of a Bad Bunch: Honestly, the only true standout in this whole 16-day slog is that Thursday, 20 August morning (Lighthouse). It’s not a classic, but with 5ft from the SSW and moderate cross-offshore wind, it’ll be the most powerful, cleanest wave we see all window. The swell direction is SSE, which works well for the break. Just remember, it’s still a short-period wave, so don’t expect long, lined-up walls. And take the forecast with a grain of salt – it’s way out there.

The rest of the days are a write-off. We’re talking about a 12-day gap with no real recommendations before that Thursday blip. It’s a classic Rhode Island summer lull. Keep your board waxed and wait.

Stay patient.
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.
