The Lowdown
Alright folks, Rusty here. Let’s get straight into it for the Inchydoney stretch.
Honestly, for the next 16 days, I’m looking at a pretty grim picture. The swell is tiny, the wind is all over the shop, and the score is a flat zero all the way through. There’s no real standout window, just a long stretch of poor surf conditions. From the 5th of September right through to the 20th, it’s going to be a tough watch. The only half-decent chance for a surf comes right at the very end of the run, but even then, it’s a long shot.
The first real sniff of anything that might work is on the morning of Sunday the 20th of September. We’ve got a moderate offshore breeze from the north at 25 km/h, which is a rare positive, cleaning things up. The swell is tiny, just 0.2m from the SSW, with a long period of 14 seconds. The combined wave energy is a weak 38, so there’s no power behind it. This is a river mouth break, so that long period groundswell might wrap in a little, but it’s going to be small and inconsistent. If you’re a beginner, this is your only window, but you’ll be fighting for scraps. The water temperature is about a touch warmer than normal for this time of year, coming in at 17°.
For the rest of the period, forget it. Strong winds, cross-on slop, and short-period windswell dominate. The 6th and 7th of September see some bigger swell, up to 1.9m, but it’s all onshore and lumpy, with fresh cross-on winds. That’s kite-surfing weather, not paddling. The 8th and 9th clean up a bit with cross-off winds, but the swell is dropping fast, under 1m, and the energy is weak. There’s a small window on the morning of the 16th of September with glassy conditions, but again, the swell is a pathetic 0.2m.
So, the bottom line: if you’ve got a kite, you might have some fun on the 6th and 7th. If you’re a surfer, wait for the 20th of September, but don’t expect much. It’s a flat spell, and it’s normal for this area to go quiet like this. Forecasts can change, but for now, it’s a long wait.
Rusty.

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