Table - best surf conditions forecast for Kerhillio over the next 16 days.
Alright folks, it’s Rusty here. I’ve looked over the numbers for Kerhillio and I gotta be straight with you – it’s a grim stretch ahead. The whole 16-day window is a write-off for any decent surf. We’re talking a full sixteen days of flat, blown-out, or just plain tiny waves.
Let’s start with the pattern. The swell energy is weak, barely a whisper, with the combined energy of all swells directed here hovering around 40 (40 kilojoules) on Saturday morning the 11th. That’s the peak of the whole run, and it’s for a pathetic 1ft wave from the west with a short, weak 8-second period. The wind is a cross-off shore on Saturday morning, but the swell is just too small to do anything with. After that, it gets worse. There’s a brief moment of flat calm on Monday morning the 13th with glassy conditions and a 0.3ft swell, but that’s not surfable.
The water is much warmer than normal for this time of year, running at 68°F – that’s 5°F above the long-term average, so it’s notably warm, but you won’t feel it on a board that’s sitting on dry sand.
The only flicker of something, and I mean a flicker, is on Wednesday the 15th afternoon. The swell bumps up to 4ft from the west, but it’s a 4-second period, which is basically wind chop, and the combined energy is still only 58 (58 kilojoules). The wind is a fresh cross-onshore at 30 km/h, so it’ll be lumpy and messy. That’s too big for beginners at 4ft for a beach break, but it’s not clean enough for anyone else. The rest of the run is just day after day of onshore or cross-onshore winds, with tiny swell that never gets above 3ft, and that’s only on the last day, Sunday the 26th, with a 3ft swell from the west with a 4-second period and onshore wind.
This is a blank run, plain and simple. There are no standouts, no hidden gems, nothing. For a spot like Kerhillio, which is fairly consistent, this is a brutal stretch. It’s the kind of run where you’d be better off checking the forecast for a different spot or just taking the time off. Don’t even bother paddling out.
Rusty.

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