The Lowdown
Alright folks, Rusty here. Let’s talk about what’s on offer for Inchydoney over the next 16 days. Honestly, it’s a tough stretch. The surf is small and the wind is a problem for most of it. We’ve got a long gap of poor conditions, but there are a couple of windows where it cleans up just enough to get a few so-so ones.
The first glimmer of hope comes on Tuesday the 8th of September. A clean morning with a light NW cross-off breeze and small 3ft swell from the SW. The energy is low though, at 130 (moderate wave energy). It’s nothing to write home about, but it’s the cleanest we’ve seen. The afternoon holds similar, with 2ft and 19 mph NW wind keeping it clean, but the swell is fading. Then Wednesday the 9th morning is glassy – absolutely dead calm with 2ft of SW swell. That’s the kind of morning you’d take a longboard out for a cruise, but the wave energy is only 53 (weak). It’s the best it’s going to get for a while.
After that, a real doldrum sets in. From Thursday the 10th right through to the 20th of September, the surf is either too small, blown out, or both. There’s a big pulse of energy on the 10th afternoon with 6ft SW swell, but the wind is a fresh 19 mph cross-on, making it a total mess (combined energy 405 – strong). That’s not for paddling; that’s more of a kite-surfing kind of day. We get a brief clean-up on Friday the 11th morning with a 3ft SW swell and a light 9 mph offshore wind from the NNW, but the energy is only 114 (moderate). Anything over 5ft here is too big for beginners, and when it’s over 8ft (no sign of that) it’s for experts only.
The best of a bad bunch comes later. On Sunday the 20th of September, the morning session looks clean again with a light WNW wind, 3ft SW swell, and 117 (moderate) energy. The water is a touch warmer than normal for the time of year at 63°F. It’s small, but it’s clean. And then Tuesday the 22nd morning offers a similar vibe: 4ft SW swell, clean cross-off wind from the WNW, and moderate energy at 115. That’s the pick of the second week.
Inchydoney is a river break, sheltered and inconsistent. It rarely gets proper, punchy waves. Given the constant onshore winds and the small sizes, there’s no standout session here. The best you can hope for is a small, clean, glassy morning with a longboard. The long periods (like the 16-second swell on the 19th) will be too straight and won’t offer much shape at a river mouth. For the experts, there’s nothing to get excited about. For the beginners, the washes are too small and messy. Keep your eye on the forecasts; things can change.

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.
