Alright, grab a coffee and settle in. Rusty here. Let’s have a look at what's going on around Block Island.

Honestly, mate, it’s a tough stretch. We’re looking at a 16-day window and honestly, the first half is a real struggle. I wouldn't bother paddling out for the first week at all. There’s hardly a pulse of decent, rideable surf until we get deep into the second week. You’re looking at a solid 13, maybe 14 days of basically flat to weak, blown-out junk before anything worth a proper mention shows up.

The water temp’s sitting around 68°F, right bang on average for this time of year, so no thermal surprises there, but you wouldn’t know it from the lack of energy.

Block Island (United States) is the only game in town, but it’s a tricky one. It’s a point break that *rarely breaks* and it often gets crowded, which is a lot of risk for very little payoff right now. The early window is full of onshore and cross-shore winds, with lumpy, choppy, messy conditions. Swell energy is weak to moderate at best—a reading of just 106 on Monday the 6th for example, and it goes down from there. You’re looking at short-period, weak windswell mostly under 3 ft, with nothing to get excited about.

Now, we do start to see a pulse of energy from the South-Southwest kicking in around the 18th and 19th of July. It’s still not clean, but the combined energy climbs to a moderate 209 (Sunday morning the 19th) with a 3 ft swell. The real standout, though, and the only one I’d even circle on a calendar, is Monday the 20th of July. We get a jump in swell to 7 ft from the SSW, with a combined energy reading of 505. That’s a solid, moderate-to-strong pulse. But there’s a massive caveat: the wind is onshore from the SSE, which is going to make it messy. At 7 ft it’s pushing into that territory where it’s really only good for experienced surfers. This spot is a point, which can handle a bigger swell, but with an onshore wind, it won’t be the clean, peeling wave you want. The period is only 8 seconds, so it's a short-period swell, more of a windswell than a clean groundswell. Still, it’s the only real window of size in the whole outlook.

So, if you’re an expert and you’re desperate for a wave, keep an eye on the 20th. But the winds will likely wreck it. For everyone else, the forecast is a long, dry spell. It’s a tough run for the area, but forecasts can change.

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.

Block Island is 33 km (20 miles) from Westerly. If you plan a vacation in Rhode Island, look for hotels and other accommodation in Westerly. Westerly has rooms for a wide range of budgets as well as car hire and transport links.
