The Lowdown

Alright, let’s get this straight. The next couple of weeks are looking pretty flat and uninspiring around here. We’ve got a long stretch of small, weak swell and mostly cross-offshore winds that’ll keep things clean but gutless. Out of the whole 16-day window, there’s really only one morning that’s going to get the heart beating, and it’s a ways off.

Right now, on the 4th, we’re looking at a pathetic 3ft of SSW swell with a short 8-second period. The wind is cross, the energy is weak (141), and the surf report is calling it poor. Honestly, it’s a lake out there. The 5th and 6th aren’t much better – we’re in that 2ft range, and the energy is dropping off a cliff (down to 50-71). There’s nothing to get excited about, just clean but tiny slop.

We’ll stay locked in this pattern through the 7th and into the 8th, with swell hovering around 3ft. The wind stays cross-offshore, which is good for keeping things tidy, but there’s just no power behind it. By the 10th, we see a slight bump, with swell pushing 4ft and the energy climbing back into the moderate range (121-168). It’s still not good, the report says poor, but at least there’s a hint of life.

The 11th through the 14th are more of the same, a whole lot of nothing. Swell stays under 3ft, and the energy is mostly weak (43-83). On the morning of the 13th and 14th, we get a bit of a glassy window with the wind going light and variable, but the waves are just too small to bother with. It’s the kind of flat spell where you’re better off fixing your dings or going for a paddle.

Then, finally, on the morning of the 15th, things look like they might turn on. We’ve got a pulse of SSW swell coming in at 6ft with an 8-second period, and the energy jumps to a solid 386. The wind is light and cross, and while it’s not glassy, it’s the most interesting surf we’ve seen all window. This is the standout, the one to keep an eye on. It’s still going to be a bit raw, with a short-period swell, but it’s the best chance for a real wave.

After that, it fades again. The 16th sees a drop back to 4ft, and then we slide back into the sub-3ft junk for the rest of the window. The 17th and 18th bring in some onshore winds and a risk of a thunderstorm, and it just looks messy, the kind of surf that’s only good for kites. The energy drops right off, down into the 18-44 range.

So, the long and short of it is: don’t get your hopes up for the next ten days. It’s flat, it’s weak, and the water’s sitting at 70°, which is about average for this time of year. The only real highlight is that Saturday morning, the 15th, where we get a pulse of real swell. It’s a ways off, so treat it as promising, not a guarantee. But it’s the only thing on the board worth planning around.

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.
