The Lowdown
Alright gang, Rusty here. Let’s break down what we’ve got for Inchydoney. I’ll tell you right now, this is a tough outlook. The whole 16-day window is a dead run – there are no good surf options on the cards. Every single session in the forecast is flagged as “poor surf conditions,” so there are no standout days or breaks. For this spot, that kind of quiet spell is more normal than you’d think, so we just have to ride it out.
From the 4th of September through the first weekend, the swell is weak and the wind is messy. We see a little bump on Sunday the 6th with waves around 5 ft out of the S, but it’s a short 6-second period and the combined energy is only moderate at 241. The wind is onshore and blowing hard at 22 mph, making it a complete mess. It stays choppy through Monday the 7th, even with a bigger 785 energy reading and a 5 ft swell from the WSW, but that 22 mph SW wind just kills it.
After that, it’s a long, drawn-out stretch of tiny surf. The 8th of September looks cleaner with a cross-off breeze, but the swell is dropping fast from 5 ft down to almost nothing. That pattern holds for days on end. The second week doesn’t get any better – we get a glassy morning on the 15th of September with no wind and a tiny 2 ft wave, but the combined energy is a weak 54. The winds are light and mostly cross-shore or cross-off, which is the only good thing, but there’s simply no swell to work with.
Water temps are about what you’d expect for this time of year, nothing unusual.
Bottom line: this is looking more like a kiting window if the wind holds, not a surfing one. Inchydoney is a sheltered river mouth that needs a decent SW swell, and we’re just not getting it. Keep your board stashed and your eyes peeled; these blank runs don’t usually last forever, but for now, there’s nothing doing.
Rusty.

A general guide to surfing at Inchydoney can be found by selecting the local surf guide option on the grey menu.

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 Inchydoney 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.
