The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the Point Judith area over the next couple of weeks.

To be honest, we’re in for a long, slow, frustrating stretch. The surf window is pretty much closed for the next week and a half, with hardly anything worth paddling out for. The first real bump of hope doesn’t show up until almost two weeks away, on Monday the 3rd of August. Before that, we’ve got a whole lot of nothing.

Here’s the rundown: The water temp is sitting at 68°F, which is about 2°F cooler than normal for this time of year – a bit of a chill in the air, but nothing a spring suit can’t handle.

The first session that has my heart beating a little faster is Monday morning, August 3rd at Lighthouse (Point Judith). We’re looking at a solid 5 ft swell from the south, with a period of 9 seconds. That’s a nice, punchy groundswell that’ll wrap in with some decent energy (combined energy of 368). The wind is light offshore from the west at 6 mph, which means the surface will be clean and glassy. This is a reef and point setup, so even with a slightly longer period, it should hold up well. The waves will be in the fun, head-high range, and with the offshore breeze, it’ll be a proper session. Just a heads up – it’s over 5 ft, so it might be a bit much for the absolute beginners, but for intermediate and up, it’s the standout of the whole forecast.

That Monday afternoon on the 3rd sees the swell jump to 6 ft from the south, with the energy cranking up to 768. That’s a lot of power, but the wind goes cross-offshore from the southwest at 12 mph. It’ll still be clean, but at that size, this is strictly for the experts – the rip will be strong, and the sets will be meaty. If you’re not confident in the bigger stuff, give it a miss.

Everything else before that date is a write-off. We’ve got weak, short-period windswell, onshore or cross-shore winds, and a lot of chop. The few days that do show a little bump (like Wednesday the 22nd and Thursday the 30th of July) are only marginal, with questionable conditions. The 30th of July morning has a clean 4 ft from the south with a gentle offshore wind, but it’s still just a one-star day at best – surfable, but nothing to write home about.

So, in short: save your energy for the morning of Monday the 3rd of August. That’s the one true standout. The waiting is the hardest part, but it’ll be worth it.

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.
