The Lowdown
Right then, folks. I'm Rusty, and I've been staring at the charts for Inchydoney. Let's be honest, it's a rough-looking 16 days ahead. We've got a river break that's sheltered, which usually means it needs a specific push to work, and that push just isn't happening for most of the run. Water temp is sitting at 61°F, which is about average for the time of year, so no surprises there.
The first sniff of anything close to decent is going to be Sunday morning, the 13th of September. It's not much – just 3ft of swell from the SW, but the key thing is that wind is glassy. For a spot like this, that's everything. The combined energy is weak (139), but at least it'll be clean for a few hours. That's your absolute best bet in this whole outlook, but don't expect much.
Then we've got a long dry spell. Monday through the rest of that week is a write-off – onshore winds, lumpy junk, and weak swell. It's just not happening.
The next time the wind lays down is Monday morning, the 21st of September. Again, we get that magic word: glassy. Swell is 3ft from the SW, and the energy is moderate (132). It'll be tiny and weak, but clean. That's your only other real window for a paddle.
After that, it's back to cross-onshore winds and messy conditions. There is a pulse of energy on the 24th of September (Thursday) with a combined energy of 328, but it's blown out by cross-onshore winds from the WSW. That one hurts.
Honestly, for Inchydoney, the highlights are few and far between. The Sunday the 13th and Monday the 21st mornings are your only realistic chances for a clean, grovelly surf. Everything else is a battle against the wind. Keep an eye on it, but don't hold your breath.
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.
