The Lowdown
Alright, Rusty here again. Let’s be honest – this is a rough stretch for Inchydoney. We’re looking at a 16-day run that’s mostly flat, with just a couple of tiny windows that might get you a splash. The water is at 66°F, which is a solid 5°F warmer than usual for this time of year, so you won’t need a thick suit, but you’ll be praying for a wave to go with it.
The first real glimmer of hope doesn’t show up until Saturday, August 22nd. Even then, it’s pretty small. That morning, a clean 1ft swell from the SSW with a long 15-second period (groundswell) is blowing in with a moderate offshore wind from the NNE. The afternoon is the real highlight of the entire period – glassy conditions with a 3 mph breeze from the ESE, and the same tiny 1ft SSW groundswell giving you clean, glassy lines. The combined wave energy is still weak at 95, so don’t expect much power, but for a river break that’s sheltered and often inconsistent, this is as good as it’s going to get. It’s still very much a beginner-friendly size, and the crowds will be there sometimes.
Sunday, August 23rd morning offers a similar setup – 1ft SSW groundswell with a clean offshore breeze from the NNE – but the energy drops slightly. The afternoon turns onshore, so it’s a morning-only session.
After that, we dive back into a barren stretch from Monday the 24th right through to Thursday the 28th. Small, weak, and often messy. Finally, on Friday, August 28th, we get a bit of a pulse. The morning shows 5ft from the SW with a short 7-second period, and a clean cross-offshore breeze from the NNE. The combined energy hits 199 – still moderate, but it’s the biggest we’ve seen. The afternoon holds similar 4ft WSW swell. The surf is ordinary but surfable, though with that short period, it’s going to be a bit lumpy and weak. Not one for the beginners.
The last few days tail off into nothing again. The best bet for a paddle is the glassy window on the 22nd afternoon. It’s a waiting game after that.
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.
