The Lowdown
Alright folks, Rusty here. Let’s get real about Block Island. It’s a rare-breaker, a point that needs a whole lot of love to line up, and honestly, the next 16 days are looking bleak. We’ve got a big gap of time with nothing to recommend, so let’s be straight about it.
The water is sitting at 67°F around the start, which is a bit colder than normal for this time of year—almost 4°F off, so stick a thicker top on if you’re paddling out.
The first chance of anything halfway decent is Thursday morning, July 23rd. A 5ft south swell with a short 8-second period pushes in, and the wind is a cross-offshore from the NE at 9 mph. That’s clean, no doubt. Combined swell energy is moderate at 291, but it’s still a weak period for a point. The problem is, this break rarely breaks, and even with clean conditions, it’s a gamble. The swell direction is south, but the optimum for this spot is SE, so it’s not a perfect match. The rest of that day and the following days are a write-off — poor surf, onshore winds, or just too small.
After that, there’s a long dry spell. From Friday, July 24th, all the way through to the end of the forecast on August 6th, it’s nothing but poor surf conditions. Swells are tiny, mostly under 3ft, and the wind is either cross-on or onshore, keeping things choppy and messy. The combined energy barely cracks triple digits most days, and when it does, it’s weak. There’s no standout, no hidden gem, just a flat, frustrating stretch. For a spot that’s already inconsistent, this kind of blank run is normal for the area.
If you’re desperate, bring a kite. The beach setups will see some wind, but for paddle surfing, it’s a no-go.
All in all, the best bet is that Thursday morning window, but it’s a long shot. Stay patient.
Rusty.

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.
