Alright, this is Rusty. Let's be straight with you – this forecast for Block Island is a tough one. We’ve got a massive 16-day window ahead of us, but it’s gonna be a long wait for anything that gets the heart pumping. For the first 12 days, from July 3rd right through to July 15th, the surf is just... poor. It’s flat, it’s choppy, it's messy. You’d be wasting your time. There’s a real desert of no-good options there.
Then, finally, things start to look interesting on the morning of Wednesday, July 16th. That morning is your standout window. Block Island is a point break, exposed to the south-east swell, and it finally gets a solid pulse. We’re talking a 7.5ft swell from the south, with a period of 9 seconds. The combined swell energy is hummin' at 866 – that’s strong energy, you’ll feel the push. What makes it special is the wind: a clean cross-offshore breeze from the west. That’s going to groom the faces beautifully. It will be a bit stout for beginners at that size, but for an intermediate surfer ready for a challenge, it’s the one. The optimum swell direction is from the southeast, and we are close enough with a south swell to make it work.
The water’s sitting at 65.7°F, which is just slightly cooler than average for the time of year – a minor anomaly, nothing crazy.
That afternoon the wind swings around and the quality drops. The next morning, July 17th, sees some leftover energy (5.2ft, cross-on breeze) but it’s choppy, and after that it fades right back out. So, if you're on the island, pencil in Wednesday morning, July 16th. The rest of the run-up to the end of the forecast on July 18th is just not worth the paddle.

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.
