Alright, Rusty here. Let's talk about what's cooking for Block Island. Gotta be straight with you – the next couple of weeks are gonna be a bit of a grind. There’s a rough patch ahead, but we might just get a little reward at the end.

The pattern shaping up is pretty grim for a while. We've got a mix of strong cross-shore winds and messy cross-chop that’s going to kill the quality for a long stretch. The water temp is sitting about average for this time of year, nothing unusual there.

Starting off Tuesday the 7th, it’s a write-off. A strong 25 mph ENE breeze is pumping in a 5 ft ESE windswell with a short, gutless 6-second period. The combined energy is a moderate 212, but it’s all cross-chop and poor conditions. That afternoon is not much better with a 6 ft swell but still a strong 25 mph wind. You’d be mad to paddle out.

Wednesday the 8th is still marginal. The morning has a cleaner look with a light 6 mph E breeze, but the 5 ft swell only has a 7-second period and the energy is 248. It's a pass. The afternoon goes sour with onshore chop again.

From Thursday the 9th right through to the morning of Monday the 20th, it’s pretty much a flat, blown-out mess. Swell sizes are mostly under 3 ft and what little energy there is gets destroyed by onshore or cross-shore winds. There’s a tiny break of clean conditions here and there, but nothing worth getting wet for. This is a solid 11-day gap with no real offers.

Now, Monday the 20th is the one highlight in the whole outlook. The morning looks bloody promising. We’ve got a clean 3 ft southerly swell with an 8-second period pushing in 221 units of moderate energy. The real kicker is the wind: calm, glassy conditions with 0 mph wind. That’ll mean silky smooth waves. The swell direction (S) matches the optimum direction for the spot.

Block Island is a point break here, and it’s rated for intermediate surfers. It rarely breaks, so when it does line up like this, it’s a special window. The water will be glassy and the peaks will be clean. That said, keep in mind the crowds come often at this spot, and with the conditions looking this good, you can bet it’ll be busy.

Tuesday the 22nd is a bit of a wildcard. The morning has a 5 ft southerly swell with a clean offshore NE wind, giving a moderate energy reading of 277. The conditions are clean, but the score is only marginal. Could be worth a look if you’re desperate, but don’t expect much.

So, there you have it. A long, dry spell, but if you’re patient, Monday the 20th is your best shot for some clean, glassy waves at Block Island.

Stay tuned, forecasts can always shift. This is Rusty, signing off.

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.
