The Lowdown
Alright, this is Rusty checking in from Point Judith.
It’s a pretty quiet stretch ahead for our little corner of the Rhode Island coast. Honestly, I'm lookin' at the next couple weeks and things are flat. Real flat. There are no green lights in sight for a proper surf session here.
The problem is, we've got a whole lot of small, short-period swell coming in from the south and southeast, but it's barely making it past a ripple. The combined swell energy is stuck in the weak zone, mostly between 12 and 42 for days, which tells you there's just no push. You've got that combo of onshore or cross-off winds from the north and east, with a side dish of rain showers later on, making the whole thing look like a mess.
Even a brief bump in swell energy up to 140 and 284 later on the 20th and 23rd brings some poor wave height, but they're attached to gusty onshore winds. While there's an offshore breeze popping up on the morning of the 28th, the swell is only 1.3 feet at a 9-second interval. It's clean as a whistle, but with no waves to speak of, it's just a pretty, empty ocean.
The very best chance we see in the whole outlook, by a long shot, is the afternoon of September 24th. The combined swell energy hits 799 with a 6.2 foot swell from the ESE and a 10-second period, but the wind is a fresh cross-onshore that will make it a lumpy, choppy, expert-only mess. The swell in the first week is barely a knee-high dribble; the only size appears after a week, but the wind ruins it. There's a reason every single forecast is rated "poor surf conditions."
Bottom line, boys and girls: leave the boards at home for the next couple weeks. Nothing's worth paddling out for. The water temp is holding average for this time of year, but she's just not giving us anything to ride.

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.
