Alright folks, Rusty here. Let’s look at what we’ve got on the cards for the next couple of weeks.
Honestly, I gotta be straight with you – it’s a rough stretch ahead. The whole 16-day window is a write-off for any decent surf. There’s nothing here that’s going to get you out of bed. We’re looking at a long, blank run with no real standouts at all.
The first few days are a total mess. Monday and Tuesday the 6th and 7th of July are plagued by onshore and cross-shore winds whipping up lumpy, chopped-out conditions. The swell is small and weak, with combined energy barely cracking 100 (63 to 99). Not worth a second look.
We do get a brief window of cleaner conditions on Wednesday morning, the 8th, at Block Island with a cross-offshore breeze, but the swell is still tiny at 5ft from the ENE and the period is short. The energy is moderate at best (168). It’s clean, but there’s just no power behind it. The next few days see more of the same: small, weak swells from the SSW with cross-shore winds keeping things average. The water temp is sitting around 68°, which is pretty normal for this time of year.
The swell picks up a bit around the 13th and 14th of July, with waves hitting 6ft to 8ft from the east. The combined energy jumps up into the strong range (272 to 498), but the wind is blowing cross or cross-onshore, turning it into a bumpy, choppy mess. That setup is honestly more interesting for the kite surfers than for paddling a regular board.
We finish the period with some glassy mornings on the 17th and 19th of July, but the swell is tiny – 3ft to 3ft – and the energy is low. It’s clean, sure, but barely a ripple.
Bottom line: surf wise, there’s nothing good to chase. The combination of inconsistent swell, poor wind direction, and weak energy means you’re better off waiting for the next system. It’s a grim outlook, but that’s how it goes sometimes.

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.
