The Lowdown
Alright, this is Rusty, and I’m looking at the forecast for Block Island. Honestly, it’s a tough one for us paddle surfers. The guidance points to a spot that’s a point break, but it’s a consistent theme: we’re in for a really long stretch of poor conditions.
The first bit of hope doesn’t show up until Thursday morning, the 30th of July. That’s our only real standout. We’ll see a 4ft swell coming from the SSE with a period of 9 seconds, and crucially, the wind is offshore from the NNW. That’s going to clean things right up. The combined wave energy is moderate (239), so there’s some push there. The water temperature is 68°, which is a bit colder than normal for this time of year, so you might want a spring suit.
But here’s the thing: Block Island is a point break that rarely breaks, so to see it even pop up with a decent score is a bit of a treat. It’s an intermediate-level wave, and with it being an offshore wind day, it’ll be clean. The swell direction is SSE, which isn’t the absolute optimum (SE is the guide’s preferred direction), but it’s close enough. Be prepared for crowds, because this spot is often busy, and when it’s the only game in town, it’ll be even more popular.
After that Thursday morning, it’s a total wipeout. The rest of the entire 16-day window is a desert. From Thursday afternoon all the way through to the 12th of August, every single entry is either poor surf conditions or marginal. You’ll see some small bumps, like a 8ft ESE swell on the 29th, but it’s cross-shore wind and a short period, so it’ll be a washing machine. That Wednesday afternoon might look interesting on paper, but it’s messy and not worth the paddle out.
There’s a tiny flicker of swell on the 11th of August with a 6ft from the NE, but the period is short (6 seconds) and the wind is cross-shore, so it’s going to be a choppy, sloppy mess. The energy is moderate (238), but without good wind, it’s just a struggle.
So, to sum it up: Thursday morning, the 30th of July, is your one and only chance. Get it while it’s clean. After that, it’s a long, blank run. For a spot that’s rarely consistent, this kind of stretch is a bit more normal. It’s a shame, but the forecasts can change, and we might get lucky. For now, I’d be looking at the kite gear if you’re into that, because the wind is going to be the main event for most of the period.
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.
