Table - best surf conditions forecast for Block Island over the next 16 days.
Alright, let’s talk Block Island. This is a point break that doesn’t break often, and when it does, it’s exposed and can get crowded.
The next 16 days start flat and weak. For the first few days, we’ve got small E swell, but the wind is blowing strong and cross-off. Nothing worth getting wet for.
Then, Wednesday morning, July 8th, we get a window: 1.5m E swell, short 8 second period, combined energy 267. The wind is glassy. Dead calm. That’s the one. Clean, rideable surf, and it’s the best wave of the whole run.
By Wednesday afternoon the wind goes cross-on and the surf turns choppy. Thursday and Friday are tiny and messy. The whole weekend into the 14th is small, weak, and cross-on junk.
On the morning of July 15th, another glassy calm setup appears. 1.4m SW swell, period 7 seconds, combined energy 219. It’ll be clean but a bit short-period. That’s your second real option, but we’re over a week out so keep watching.
Then a long gap of poor surf until the 19th. That afternoon, the swell jumps to 3.5m from the SSW, 9 second period, combined energy a massive 1777. That’s expert-only size, but the cross-on wind will ruin it for paddling.
July 20th morning keeps that 3.5m S swell, 10 second period, energy 2055. Wind is light cross-shore. Still huge, heavy, and for experts only. The afternoon is cross-onshore and messy.
Finally, on the morning of July 21st, another glassy moment: 1.6m S swell, 8 second period, energy 356. Clean and solid for intermediate surfers.
So the standout is July 8th morning – 1.5m E, glassy. Second best is the 21st morning – 1.6m S, glassy, but further out. The 15th is a backup.
Water temp is about 20°C, average for the season.
Crowds will be a thing when it’s on, because this spot doesn’t work often.
Keep the wax warm.

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.
