Alright, this is Rusty. Let’s talk about what’s happening around Block Island.
Honestly, it’s a grim outlook for the next couple of weeks. We’ve got a solid 16-day window here, but the first stretch is basically a write-off. From Saturday the 4th right through to Friday the 17th, the surf is either tiny, messy, or blown out. There are gaps of several days where there’s just nothing worth paddling out for. The wind is mostly cross or cross-onshore, and the swell is weak, short-period junk. You’ll see combined wave energy mostly under 200 (weak to moderate) and a lot of choppy, lumpy conditions.
The water temperature is sitting around 19° – that's about average for this time of year, so no surprises there, but it won’t help the quality.
Now, the one bright spot – and it’s a long way off – is Saturday the 18th. The afternoon finally shows some promise. We get a clean, cross-offshore breeze from the west at 9 mph, with a southwest swell pushing in at 5 ft. The period is 7 seconds, so it’s a short-period wind swell, but with that clean wind, it should shape up. The combined energy jumps to 258 (moderate), so there’s some push behind it. This is the standout of the entire run, but being two weeks out, keep your expectations in check.
This spot is a point break (Block Island) that rarely breaks, so if it does come together, it’s a special deal. It’s exposed to the south-east, and the swell direction is southwest – a bit off the optimum of SE, but with clean conditions, it could still be fun. The crowds are often around here, so you won’t be alone if it fires.
On Sunday the 19th morning, there’s a glassy moment with a 4 ft southwest swell and a 7-second period. Combined energy is 172 (moderate). It’s surfable, but very ordinary. Not a headliner, just a consolation prize for those who missed Saturday.
That’s the long and short of it. A lot of flat or ugly days, and one date circled on the calendar. Stay tuned, forecasts can shift.
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.
