The Lowdown
Alright, Rusty here. Let's cast an eye over the next sixteen days for this stretch of coast. To be straight with you, it’s a tough watch for the most part. There’s a proper run of grim days before we get a glimpse of something half decent, and even then, it’s not going to be world-class.
The first real chance of a surf comes Tuesday morning, 22nd September. It’s a tiny little thing with swell at 1.6ft from the WSW, but the kicker is the wind – dead calm, glassy. At Inchydoney, a river break that’s sheltered and usually inconsistent, that glassy surface is a major positive. The water temp is 61°, which is about normal for the time of year. Even so, the wave energy is weak (93), so you’re looking at a small, clean roll. The afternoon turns onshore with a Southerly breeze, so that morning window is the one.
Wednesday the 23rd is a write-off with small, weak, onshore junk. Thursday the 24th is even smaller. A real flat spell.
Then we jump to Saturday the 27th of September. The afternoon shapes up with offshore wind out of the North, around 2ft of swell from the WSW. That’s clean, rideable, but tiny. The morning of the 28th also looks clean with a light Northerly, but again, it’s ankle to shin high. Nothing to get excited about.
Now, here’s the one standout in the whole pack – Saturday the 26th of September. We see a surge of long-period groundswell, a solid 4.3ft from the WSW with a very long period of 15 seconds. The combined swell energy jumps to strong (774). That’s serious power for this spot. The catch? The wind is cross-onshore from the SSE, which will chop it up and make it messy. This is a sheltered river break, and a long-period swell like that can wrap in nicely, but the wind is going to be a problem. For a beginner, 4.3ft is okay, but the conditions won’t be friendly. It’s likely to be more interesting for a kite surfer than a paddle surfer on that particular day.
Honestly, the best on offer in this whole 16-day window is that glassy Tuesday morning, the 22nd. It’s not big, but it’s clean. The Saturday the 27th afternoon is a close second for clean, tiny waves. Everything else is blown out, tiny, or both. The water stays around average temps the whole time.

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.
