Table - best surf conditions forecast for Block Island over the next 16 days.
Alright, let’s break it down.
It’s a tough stretch ahead here at Block Island. This is a point break that only rarely fires up, and honestly, most of the next two weeks are going to have you staring at flat, messy, or just plain unappealing conditions. The water’s sitting at about 68°F, which is pretty much normal for this time of year. Nothing to write home about.
The whole run starts with a real dud. Tuesday the 7th has light rain and a stiff 28 mph cross-offshore wind, but the swell is a weak 3 ft from the ESE with a short period of 6 seconds. The energy is pathetic (105), and it’s just poor surf.
Wednesday morning the 8th is the one true standout in the entire forecast, so pay attention. We’ve got a 6 ft swell from the ENE with an 8-second period, and the combined energy jumps up to a moderate 547. What makes this the pick is the wind: a light 6 mph from the NE is cross-offshore, meaning clean lines. The forecast says “very good surf conditions.” This is your window. Get out early. The swell direction isn’t a perfect match for the spot’s optimum (SE), but with that size and clean wind, it’s the best on offer. Keep in mind, this spot rarely breaks, so if you see it working, don’t hesitate. Crowds are likely here when it’s on.
From Wednesday afternoon onward, it’s a long, bleak run. The wind swings onshore or cross-shore, and the swell drops off into the 2 ft to 4 ft range with short periods and weak energy. Thursday the 9th through to Monday the 21st is basically a write-off. There’s a brief flicker on Sunday the 19th morning with glassy conditions and a 3 ft SSE swell, but the energy’s still low (115) and the period is short. It’s not going to be worth paddling out for.
Later on, Monday the 20th and Tuesday the 21st see the swell pick up a bit – 4 ft to 5 ft from the SSE and S with 9-second periods and energy around 300. But the wind is cross-onshore or onshore, chopping it up. For a spot that rarely works, these are not the conditions to roll the dice on.
Overall, Wednesday morning July 8th is your only real chance. The rest of the 16-day window is a bust. Don’t hold your breath.

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.
