Alright, let’s look at Carrownisky in feet and miles per hour. The outlook is basically the same, mate—it’s a tough read for the next couple of weeks.
There’s a big gap from the 6th of July onward, with no decent surf. We’re talking weak, tiny swell with barely 1 to 2 feet of wave height, and cross-onshore winds making a mess of it. The wave energy is in the low double digits, nothing to write home about.
Things clean up a bit around Saturday the 11th of July, with the wind turning light and cross-offshore. The swell is still tiny, only about 1 foot from the WNW, but the surface will be clean. For a beginner on a foamie, you might just find a little 1-foot bump to practice on. Sunday the 12th is even smaller, with waves barely breaking.
The best of a bad situation comes from Monday the 13th of July onward. The wind goes fully offshore from the east, and while the swell is still pathetic—only 0.3 to 0.6 feet—the conditions will be glassy. Carrownisky is a very consistent, beginner-friendly spot, so even these tiny clean ripples offer a chance to learn. The water is sitting at about 59°F, which is spot on for the season.
But let’s be honest, there is no proper surf forecast here. For anyone wanting a wave you can actually ride, it’s a no-go. The long blank run is pretty standard for this area when the swell is out.

Information about the Carrownisky Surf forecast
The above surf forecast table for Carrownisky provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Carrownisky can be found by selecting the local surf guide option on the grey menu. Our Carrownisky 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 (Carrownisky) 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 Carrownisky 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.
