The Lowdown
Alright, let me tell you what's cookin' at Lighthouse (Point Judith) for the next couple of weeks.
Honestly, we’re looking at a pretty grim stretch of small, weak surf. The first week and a half is a real struggle. From Tuesday, September 15th, right through to the 22nd, it's just tiny, mostly messy waves. We're talking knee-high or less, with hardly any energy behind 'em – the combined swell energy barely gets past the 20s or 30s. The wind is all over the place, mostly onshore or cross-shore, keeping things choppy and frustrating. The water temp is at 69°, which is pretty normal for this time of year, but it won't matter much when you're bobbing around on waves that are barely there. There's a brief moment of hope on Friday the 18th afternoon when it goes glassy, but with a tiny 1ft easterly swell... it's just a tease.
Finally, things start to look a bit more interesting late in the window. It's a long wait, but around Wednesday the 23rd of September, things are shaping up. There's a noticeable pulse of energy arriving. On Wednesday morning the swell picks up to 6ft from the ESE, with a combined energy of 266 – that's some proper push. It's a bit raw and cross-off in the morning, but by the afternoon it cleans right up with a light offshore wind from the W, dropping to 6ft. That's the standout moment here. That's solid, clean surf. The swell period is only 6 seconds though, so it'll be a bit of a choppier,
The following Thursday the 24th is a mess with onshore winds, and after that it fades back down to small and clean but weak stuff for the 26th and 27th. So, if you've got some patience, that Wednesday the 23rd afternoon is your best bet for a proper session at the Lighthouse.

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.
