Updates in hr min s Forecast update imminent
Alright folks, Rusty here. Let’s have a look at what’s on the table for Block Island over the next few weeks. Gotta be honest with you straight up – this one’s a tough stretch. There’s not a single standout session in the whole 16-day window. The forecast is a long, flat, choppy mess with hardly a window of clean, rideable surf. We’re looking at a blank run from now, starting Friday July 3rd, right through to Saturday July 18th. That’s a solid two weeks with nothing worth paddling out for.
The energy in the water is weak for the first week, with combined swell energy values barely scraping past 100 (like 91 on Friday morning, 100 Friday afternoon). Even when we see a bump in size around Tuesday July 7th, with waves hitting 6.2 ft from the ESE, the period is a short 6 seconds and the wind is cross-onshore. That combo gives you messy, lumpy lines – more of a kite-surfing setup than a paddle session. The combined energy on that Tuesday hits 269 (moderate), but the quality just isn’t there with onshore winds and rain.
Water temps around the island are sitting at about 65.7°F, which is pretty normal for this time of year – nothing weird going on there.
We get another pulse of size around Wednesday July 15th, with swell going 5.9-7.2 ft from the south, combined energy pushing up to 440 (strong). But again, the wind is howling from the SW at 15-16 mph and it’s cross-onshore. That’s big, blown-out, lumpy slop. Not for beginners (anything over 5 ft is getting too much for them), and honestly not much fun for anyone unless you’re on a tow board.
There is absolutely no day with glassy or offshore wind conditions and a decent swell. The few mornings with clean conditions, like Saturday July 4th morning, have waves a tiny 1.3 ft from the SE – barely a ripple.
Block Island (point) is an exposed spot that rarely breaks, and with this outlook, it lives up to that reputation. No standout options. No hidden gems. Just a long, quiet spell.
Hang tight, folks. It tends not to stay this poor forever, and forecasts can shift. But for now, leave the boards in the van.

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.
