Alright folks, Rusty here. Let’s have a look at what Block Island’s got cooking for the next couple of weeks. I’ll be straight with you – this outlook is a tough one. The finder didn’t serve up a single recommendation across the entire 16 days, which tells you all you need to know about the quality on offer. It’s a blank run, and for this area, that kind of run can happen when the swell and wind just won’t line up.

The overall pattern is pretty grim. We’ve got a mix of small, weak swell and a lot of cross-onshore or messy wind. The water temp at the start is sitting at 66° which is about 3° colder than normal for this time of year – definitely on the nippy side, so you’ll want a good wetsuit.

Let’s walk through it chronologically. The first surf we see is on Sunday, July 12th afternoon, but it’s a total dud. We’re looking at a tiny 2ft swell from the south, period of just 7 seconds, with an onshore breeze. The combined energy is only 36 – that’s weak, barely a ripple. The call is “poor surf conditions,” and I’m not paddling out for that.

Monday the 13th and Tuesday the 14th are much the same story. Small, weak swells, a bit of cross-onshore wind, and everything tagged as poor. On Tuesday afternoon, the swell bumps up to 7ft from the SW, but the period drops to 6 seconds and wind is strong cross-onshore at 28 mph. The energy hits 308, which is moderate, but the quality comment is “messy.” That’s blown-out, lumpy junk. For a beach and reef setup, this looks far more interesting for kite surfing than paddle surfing.

Wednesday the 15th through Friday the 17th is still a write-off. We get some cleaner windows on Friday morning with a light offshore from the NW, but the swell is barely 2ft with a short period. You could probably float around on a log, but there’s nothing to ride.

Saturday the 18th and into the next week doesn’t get any better. There’s a pulse on Monday the 20th with a 5ft to 7ft SSW swell, period around 6 seconds, but the wind is onshore or cross-onshore. The energy climbs to 298 on Monday afternoon, so there’s power, but with those onshores, it’s going to be a choppy, ugly mess.

The rest of the period into late July just repeats the theme: small swell, cross-onshore wind, poor conditions. There’s no standout day, no hidden gem. If you’re desperate for a paddle, maybe Friday the 17th morning with the offshore wind and clean conditions, but you’ll be surfacing more than surfing on that 2ft dribble.

Stay optimistic though – forecasts can change, and it tends not to stay this flat and messy forever. But for now, I’d save the gas and wait for the next update.

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.
