The Lowdown
Alright, Rusty here. Let me break it down for Inchydoney.
Looking at the full 16 days, and I gotta be honest with you, it’s a whole lot of nothing. Almost every single session is a dud. The river mouth is barely showing any life, and I’m not seeing a single day that I’d call good. You’re gonna need some patience.
The water temp is sitting at about 65°, which is a touch warmer than usual for this time of year. That’s the only bright spot.
From Wednesday the 12th all the way through to Friday the 21st, it’s all tiny waves under 3 feet. On Wednesday the 12th, there’s a 3-foot swell from the SW with a period of 9 seconds, but the wind is onshore from the S at 9 mph, and it’s just poor. By Friday the 14th, the wind turns cross-offshore from the NW, but the swell drops to 2 feet. It’s clean, but barely a bump.
The mornings on the 15th and 16th are clean with offshore winds, but the swell is tiny, around 1 foot or less. You could sit out there, but you won’t be riding much.
We get a little bump around Tuesday the 18th with a 3-foot swell from the SW, but the wind is a fresh cross-shore from the W at 22 mph, making it lumpy and choppy. Not for surfing. The combined wave energy hits 103 (moderate), but the quality is still poor.
Towards the end, on Thursday the 27th, there’s a 4-foot swell from the WSW, but the wind is a fresh cross-shore from the W at 22 mph, and the period is a terrible 5 seconds. That’s just wind chop. By the afternoon the wind goes offshore from the NNW, but the swell drops to 3 feet with a 4-second period. Still messy.
Because it’s a river break, it’s sheltered, but with such weak swell and bad wind, there’s nothing going on. Even the clean days with offshore wind only have 1 to 1-foot waves. For kite surfers, the windier days on the 18th and 27th might look fun, but for a paddle surfer, you’re better off waiting for the next proper swell.
This is a dry spell for Inchydoney. It won’t stay flat forever, but right now, there’s nothing worth your time.
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.
