The Lowdown
Alright, I’ve had a good look at the charts for Block Island, and I gotta be straight with you – it’s a tough stretch. This is one of those times where you might be better off waxing the longboard for a dusty cobweb removal than paddling out.
We’ve got a rare point break here on Block Island that needs a specific SE swell direction to really wake up, and it hardly ever breaks. Looking at the whole 16-day run from August 1st, we are looking at a real dry spell. There’s nothing on offer for the first week. The waves are tiny, the wind is ugly, and everything is labeled “poor surf conditions.”
We finally see a little glimmer of hope on Tuesday morning, August 4th. The wind swings light from the NW, which cleans things right up and gives us a brief window of clean conditions with a SSW swell around 6ft. The combined energy is a moderate 392. But that's it. That's the only real bright spot in the whole run, and it’s just a morning window before the wind turns ugly again. For a spot that "rarely breaks," getting a clean window is a big deal, but the swell direction is SSW, not that optimum SE. It's a promising but lonely standout in a desert of flatness.
After that, it’s back to small, wind-affected slop. We get another clean-looking morning on Wednesday, August 12th, with a light northerly offshore wind, but the swell is tiny at 2ft with weak energy (56). It's clean but barely surfable.
To be honest, from August 1st through August 16th, there’s only that one Tuesday morning that offers anything decent. The rest is a long, flat, blown-out gap. The setup looks more interesting for kite surfing than paddle surfing for most of it. This kind of blank run is pretty normal for the area when the swell direction isn’t cooperating.
Rusty out.

Information about the Block Island Surf forecast
The above surf forecast table for Block Island provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Block Island can be found by selecting the local surf guide option on the grey menu. Our Block Island 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 (Block Island) 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 Block Island 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.
