Table - best surf conditions forecast for Block Island over the next 16 days.
Alright, Rusty here. Let's have a look at what's on the menu for the next couple of weeks.
Honestly, it's a tough one to start. We're looking at a long stretch of pretty poor surf. The first real recommendation doesn't pop up until the 21st of July, so we're talking about a solid ten-day gap with nothing worth paddling out for. The waves are just too small, the wind is all over the place, and it's just not happening.
Block Island is a point break that rarely breaks, so it's a bit of a special spot. For the first ten days, forget it. Small swell, rotten wind directions – it's a no-go.
Then, on Tuesday, the 21st of July, we get a bit of a pulse. The swell direction is from the S, about 8ft, with a period of 8 seconds. The combined energy is strong (732). That's a solid size. For a spot that's rarely breaking, this is a real event. The morning has a clean, cross-off wind from the NE, which is a major positive. However, that 8ft is big. It's in the expert-only zone. This is the standout of the whole forecast, but it's not for the faint-hearted. It's also a point break, so the long period swell (8 seconds is moderate) might actually be better here than at a beach. Crowds are possible at this spot.
Thursday the 23rd still has some size, around 5ft from the S, but the wind is a cross-on from the ESE, which will chop it up. Not a patch on the 21st.
So, if you're an expert, mark the 21st of July on your calendar. For everyone else, it's a waiting game. The water temperature feels about average for the time of year.
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.
