The Lowdown
Right then, let’s have a look at what’s on the cards for Inchydoney. It’s a bit of a slow start, I won’t lie to you. The first few days are looking pretty flat with only knee-high slop on offer, and that wind is just all wrong. You’ll be battling a stiff cross or cross-off breeze for most of the first week, and the swell energy is weak, barely registering over 100 (106) at its best. The water temp is about average for the time of year, nothing to write home about.
We’re looking at a real gap in quality surf right through until the 25th of August. There’s a tiny window on the afternoon of the 22nd of August where the wind drops right off to a light breeze and the conditions clean up, but the swell is still only 1 ft from the SSW. It’s surfable, but ordinary. Forgive me for being blunt.
Then, out of nowhere, the 25th of August afternoon kicks in. The wind swings to a gentle cross-off from the NW, and the swell jumps to 8 ft from the SSW with a short period of 8 seconds. The combined energy is massive at 1696. This is a powerful, lumpy wave that’s going to be a handful. It’s clean, but that size is only for the experienced crew. Beginners, stay well clear.
The rest of the run into early September is a real mixed bag of onshore winds and messy conditions, with a few clean patches but nothing to get excited about. The 2nd of September morning looks like the next solid chance with a 6 ft SW swell, clean conditions from a light NW cross-off, and moderate energy (439). It’s the best of a pretty average outlook.
So, to be honest, if you’ve got the skills, the standout is the afternoon of the 25th of August – that’s your big, clean, powerful session. For everyone else, the morning of the 2nd of September is the most promising for a fun, clean wave, but it’s a long way off and the forecasts could change.

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.

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.
