The Lowdown
Alright folks, Rusty here. Let’s talk about what’s on the menu for Block Island over the next couple of weeks.
Honestly, straight up, the outlook is a bit of a tough one. We’ve got a long stretch of very ordinary conditions, and I mean *ordinary*. The first hint of anything decent doesn’t arrive until the morning of Thursday, July 30th. That’s a full week of paddling around in flat, choppy, or wind-affected slop before we get a sniff of something real.
The standout session, and really the only one I’m getting excited about, is that Thursday morning, July 30th. We’ve got a clean, waist-high plus swell from the SSE rolling in with a little bit of period, around 9 seconds. The wind is light and cross-off from the west, which is a dream for this spot. Wave energy is moderate (245), and it’s going to be clean. The best part? The crowd situation at Block Island (point) can be a bit of a battle, but it’s a point break, and with a little S swell, it should line up nicely. The water temp is about average for the time of year, nothing weird to report.
Don’t get too excited about the afternoon of the 30th, though. The wind swings southwest and gets on it, blowing the top off that 5ft swell. It’ll be a choppy mess.
Before that, the morning of Thursday, July 23rd, offers a brief glimmer. A clean 5ft swell from the S with a light cross-off breeze, wave energy at 252. It’s the first decent wave on offer, but the period is a short 8 seconds, so it’ll be a bit weaker and more broken up than ideal. It’s surfable, but not the full power.
After the 30th, it’s pretty much back to the same story. The morning of Tuesday, August 4th, is worth a mention. A clean 4ft S swell with a light cross-off wind from the west, but the period is only 7 seconds and the wave energy is moderate (180). It’s a flat, weak wave, and the crowd at Block Island point is likely to be there, so it’s really just a paddle for a few grovelly ones.
The truth is, the consistency is shocking. This spot rarely breaks, and this forecast shows that. You’re looking at a blank run of about 7 days before the first real surfable window, and then it’s mostly poor again. It’s a quiet spell for the island. We’ll see if the forecasts change, but for now, keep your eyes on that Thursday, July 30th morning.
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.
