Alright folks, Rusty here with a look at the upcoming surf window for Block Island.
Right off the bat, I gotta be straight with you – the charts are looking pretty bleak for the next couple of weeks. We've got a long stretch here where it's just not gonna be worth paddling out. From now through the 16th of July, every single session is rated as poor. The winds are mostly onshore or cross-shore, and the swell is either tiny, short-period junk or blown out. You're looking at a solid 11-day gap with nothing to get excited about.
The only day that even gets a nod of recognition is Friday the 17th of July. On the morning of the 17th, we might see some surfable waves but in very ordinary conditions. It's clean, with a light breeze from the West at 9 mph, and the swell is from the SSW at 4ft with a 6-second period. The combined energy is moderate at best (151). It's not a standout, it's just the only thing on the menu that isn't a total write-off. Don't expect any magic.
There's a big pulse of swell that shows up on Monday the 13th of July, with an 8ft SSW swell, but it's all onshore wind from the SSE with a moderate breeze, and the wave comment says "poor surf conditions". That's a messy, blown-out mess for the experts only, and I wouldn't even bother.
Block Island is a rarely-breaking point break, and this is one of those times where it's living up to that reputation. It's a tough run of weather and swell. The water temp is sitting at 68°F, which is normal for this time of year, but you won't be feeling it because you'll be on the beach.
Hang in there, lads. It can't stay this quiet forever.

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.
