The 10 sunniest places within 15 hours of Vienna

Ranked on sunshine in September alone, among well-known places (a Wikivoyage travel guide and at least 40,000 Wikipedia readers a year), one per area and at most three per country. The carbon is shown, not used to choose: the list further down is the other question, how much sunshine each extra kilogram buys.

≈ is the model's estimate (air times include getting to and through the airport); ✓ is a rail journey checked against a real timetable, with the date it was checked. Temperatures are historical daily means for 2023–2024, averaged across day and night, so afternoons run warmer.

The low-carbon trade-off

The sunniest place you can reach from Vienna in September within 15 hours is Izmir, 11.6 h, costing 350 kg CO₂e return. The lowest-carbon option is Prostějov at 4.4 kg — 80× less carbon, for 2.1 hours less sunshine.

Every destination here is on the efficiency frontier: nowhere else this site covers is both sunnier in September and lower in carbon. Anything a better option beats outright has been left out.

Warm is not the same as pleasant, which is why sunshine and rainfall are shown alongside temperature. All three are ERA5 monthly means for 2023–2024.

Where the curve breaks

The frontier is gentle until it isn't. Going from Taranto (25.5 kg, 11.0 h) to Izmir (350 kg, 11.6 h) buys 0.6 hours more sunshine for an extra 325 kg — 541 kg of CO₂e per hour. That single step is the most expensive sunshine on the whole curve.

The same month, asked differently

September answers differently depending on what you are after, and the lists genuinely diverge: the brightest places are not the hottest, and in summer the useful question stops being where is warm at all.

Questions

Where is the sunniest place to go from Vienna in September?

Izmir, Turkey, at 11.6 h. Reaching it emits 350 kg CO₂e return, travelling 5h 24m each way by air (modelled).

Can I get somewhere sunny from Vienna in September without flying?

Yes. Taranto reaches 11.0 h and is reachable by rail or ferry in 14h 24m (modelled), emitting 25.5 kg CO₂e return — though Izmir is sunnier still, if you fly.

How much carbon does a return trip from Vienna to Izmir produce?

350 kg CO₂e for one person, return, by air. That uses the UK Government's 2026 conversion factors, including radiative forcing for flights.

Carbon uses UK Government (DESNZ/DEFRA) 2026 conversion factors applied to great-circle distance, with radiative forcing included for flights. Rail journey times are modelled estimates, not timetabled services. Full method · download the data.
