The Lowdown

Alright, Rusty here. Let's talk about what we've got on the cards for Block Island over the next couple of weeks. I'm not gonna lie to you, it's looking like a bit of a waiting game. We're staring down a long, dry spell here.

The whole picture is pretty flat for a while. We don't see any real action coming in until Thursday morning, July 23rd. Before that, forget about it. Wednesday the 22nd is a total write-off – we've got a lumpy cross-shore wind and a messy 7ft southerly swell that's just blown out. The combined energy is a moderate 603, but with that wind and a short 8-second period, it's not doing anyone any favours. Water temperature is sitting at 67°, which is a bit colder than normal for this time of year.

So, your first real chance to get wet doesn't come until Thursday morning, the 23rd. The swell drops to 5ft from the south, and the wind swings around to a light NE offshore. That's clean surf, and the energy drops to 298. It's small, but it's rideable. Later that afternoon the wind goes light cross-onshore and the quality drops right off.

From there, it's a grim stretch. Friday the 24th through to Tuesday the 29th, the swell is tiny, the period is short, and the wind is mostly onshore or cross-shore. We're talking mostly under 3ft and combined energy below 200. Wednesday the 29th morning sees a clean cross-off wind from the WNW, with a 5ft south swell (257 energy), but the "poor surf conditions" call is still there, so it's not a standout.

Now, if you're looking for the one and only real bright spot in this whole 16-day run, you have to set your sights on the morning of Sunday, August 2nd. It's still over a week away, so keep that in mind, but the models are hinting at something. We have a 7ft southerly swell rolling in with a moderate 559 combined energy. It's a solid bump of swell, and the wind is a moderate cross-shore from the WSW. The report calls it "marginal," but this is the biggest swell of the entire period. It's not perfect, but it's the best option we have by a long shot. With that size, it'll be too much for beginners – more for the experienced crew out at Block Island. The afternoon goes back to choppy cross-on junk.

After that, it fades again. Monday the 3rd has a clean morning with a small 3ft SE swell, but nothing to write home about, and the rest of the week looks tiny.

Honestly, the first week and a half is mostly a blank run. For Block Island, this is a pretty typical quiet stretch. The only day that even gets close to being a recommendation is Sunday, August 2nd. It's a long-range promise, so temper your expectations, but that's the one to circle on the calendar if you're desperate for something with a bit of push.

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.
