The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s coming up for Lighthouse (Point-Judithlighthouse). It’s a reef and point setup, exposed to the south, so it needs a decent southerly kick to get moving. The water temp is about average for the time of year, nothing unusual there.

We’ve got a bit of a slow start, but honestly, there’s not much to get excited about for the first few days. Sunday the 19th and Monday the 20th offer small, weak swell. The standout is Monday morning, the 20th, with clean, glassy conditions. The swell is tiny at 3 ft from the south, and the combined energy is low (90). It’s not a wave you’d paddle out for, but if you’ve got a longboard and you’re desperate, it’ll be the cleanest of the small stuff.

The real hope comes on Wednesday the 22nd. We’ve got a solid pulse of swell pushing in, with heights around 7 ft to 7 ft from the south. The combined energy is strong (616 to 775), so there’s real power. The wind is cross-offshore from the SW, keeping things clean. This is a bigger, more powerful wave, and over 7 ft, it’s really only for experienced surfers. The period is short though, around 7 to 9 seconds, so it’ll be a bit lumpy and less organised than a true groundswell, but the reef and point will handle it better than a beach break.

Thursday morning the 23rd is the best of the whole run. Swell holds at 6 ft from the south, with a period of 9 seconds. The combined energy is still strong (586), and the wind swings light out of the north, giving us a clean, cross-off breeze. The conditions are set to be very good. This is the one to circle on the calendar. After that, the swell drops off quickly. Friday the 24th sees 4 ft from the SSE, but with a light onshore breeze, it’s not as clean. The combined energy is moderate (276).

From Saturday the 25th all the way through to the end of the first week of August, the surf goes flat or near flat. There are gaps of several days with no real recommendations. The swell drops to under 3 ft, and the energy is weak. There’s a brief pulse around Tuesday the 28th of July, with 5 ft from the SSW, but the wind is cross-off, so it’s just surfable, not special. The combined energy is moderate (176). Then it fades again.

Into the second week, we’ve got a small uptick on Sunday the 2nd of August. It’s 3 ft from the south, with a light cross-off breeze and weak energy (91). It’s surfable, but nothing to write home about. Monday the 3rd of August is glassy and tiny at 2 ft. Don’t expect much.

The true standout is Thursday the 23rd of July, morning session. That’s the best of the swell, with clean conditions. Wednesday the 22nd is also a good option for those who can handle the size. Everything else is small, weak, or blown out. Keep your eyes on that Thursday morning.

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.
