Updates in hr min s Forecast update imminent
Alright folks, Rusty here. Gotta be straight with you – the next couple of weeks are looking real quiet for Block Island. The good news is, there's nothing dangerous out there, just a whole lot of nothing for surfers.
Looking at the full 16-day window, we start off pretty flat and it stays that way. The first swell worth paddling for doesn't even show up on the calendar. For the first week of July, from the 4th right through the 11th, we're looking at weak, short-period swell with poor to fair winds. You'll see tiny waves on the buoys, but with onshore and cross-shore breezes making a mess of things, it's just not worth suiting up. Even the so-called 'clean' days are on tiny waves.
The best chance to get wet around here might actually be midweek, around Wednesday the 10th, into the weekend of the 13th and 14th. But let's be real, we're talking about ankle to knee-high slop. The water temp is sitting around average for the time of year, so no surprises there.
Honestly, for the first 10 days, the strongest energy we see is moderate (values in the 100-200 range), and that's with the wind howling from the wrong direction. For a spot like Block Island that rarely breaks, this is a tough run. It’s not unusual for this area to have blank spells, and this is a prime example.
We finally see a slightly more interesting pulse of energy building late in the second week. Around Saturday the 18th and Sunday the 19th, the combined swell energy jumps up to 372 and 497 (moderate to strong energy), with waves pushing to 5ft to 6ft from the south. However, the wind will be fresh cross-on from the SSW, making for lumpy, messy conditions. This is the kind of setup that looks more interesting for kite surfing than paddle surfing out at the point. For the dedicated surfer, if you have to go, the cleanest window might be a glassy morning on Sunday the 12th, but that wave is just 3ft and weak.
There’s really nothing to get excited about here. I wouldn't be planning a trip to Block Island for a surf for at least the next two weeks. Things might change, but right now it’s a big ol' dud.
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.
