The Lowdown
Alright folks, Rusty here. Let's have a look at the surf situation for the Point Judith Lighthouse area.
Honestly, it's a pretty bleak 16 days on the whole. We're looking at a whole lot of small, weak surf with poor conditions. The water temp is sitting at 72°, which is about average for this time of year, nothing to write home about.
The first few days are a write-off. Sunday the 16th through to Wednesday the 20th of August is a long stretch of tiny waves with messy wind or no energy. The combined swell energy is struggling into the double digits (20) at the start, barely climbing into the hundreds by the 18th and 19th, but the waves are all under 3 feet with short 6 to 8 second periods and onshore or cross winds making a mess of things. You'd be battling chop for nothing.
Thursday the 21st through to Monday the 26th of August looks like more of the same – small, weak, and mostly poor. We do get a little bump on Wednesday the 26th with 3 feet of south swell and energy hitting 130, but it's blown out by a cross-onshore wind. Not worth paddling out.
The only real glimmer in this entire outlook comes right at the end. On Thursday the 27th of August, we've got a clean-up in the afternoon. The wind goes glassy, calm as can be, with a 2 foot swell from the south-east. The period stretches to a decent 11 seconds, so there's some long-period groundswell energy in there, and the energy reads 120. It’s small, but for the point and reef setup, that long period should wrap in clean and make for some smooth, peelable lines if you're on a longboard or a fish. Friday the 28th morning is also promising with a light offshore wind from the northwest and similar 2 foot surf, clean as a whistle. It’s still tiny, but it’s the only time in the whole window you'll find a truly clean wave face. These are the best on offer.
Because the waves barely crack 3 feet, this whole period is fine for beginners to be out learning, just don't expect much push. The bigger issue is the lack of quality. This is a proper flat spell. Forecasts can change, but right now, don't hold your breath.

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.
