The Lowdown
Gap at the start, no question. From Wednesday the 16th to Monday the 21st, it’s a write-off. Cross-shore winds, lumpy chop, weak swell. Combined energy is stuck low—62, 26, 149—nothing with any punch. You’d be fighting for nothing. Sunday the 20th is glassy with 2ft but no push, and Monday the 21st has 0.7ft with a long period that’s going nowhere. Save your energy.
Tuesday the 22nd starts stirring, but it’s still poor. Morning has 1ft with an 18-second period and energy at 109, but the direction’s off. Afternoon gets 1ft but it’s bumpy and cross-onshore. Wednesday the 23rd is more of the same. Thursday and Friday are ordinary—rideable moments, nothing special. Wind stays messy.
The window opens Sunday the 27th. Finally, offshore light winds from the north, clean conditions. Swell is small—around 3ft—but it’s clean, with periods around 10 seconds and energy at 158 and 173. It’s not big, but it’s surfable, and after a week of nothing, you’ll take it.
Monday the 28th is the standout. Morning has 2ft from the west, 13-second period, offshore north wind at 20 km/h, energy at 152. Afternoon is better: 2ft from the WSW, 12-second period, light north wind, clean, energy at 154. This river break here at Inchydoney is sheltered, and with this clean, lined-up swell, it’ll be fun. It’s small enough for beginners, and crowds are only sometimes, so you might get some space. This is the best of the run.
Tuesday the 29th starts clean but the afternoon turns sour with fresh east winds and lumpy chop as a short-period south swell rolls in at 5ft. That’s a drop-off. Wednesday the 30th is choppy and messy.
Thursday the 1st of October looks promising—4ft from the SSW, east-northeast offshore at 10 km/h, clean, and energy at 300. That’s got push. It’s a long way out, so don’t bank on it, but it could be a decent finish.
Overall, first week’s a bust, then the 27th and 28th are your best bets, with the 28th a clear standout. The 1st is a promising maybe. Water temp’s about average for the time of year. Keep expectations low early, and you’ll be rewarded later.

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.
