The 10 sunniest places within 15 hours of Sheffield

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.

The low-carbon trade-off

The sunniest place you can reach from Sheffield in September within 15 hours is Izmir, 11.6 h, costing 689 kg CO₂e return. The lowest-carbon option is Colwyn Bay at 12.1 kg — 57× less carbon, for 4.8 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.

By rail or ferry By air

Carbon against sunshine, September, departing Sheffield. Journeys of up to 15 hours each way.

What the 15-hour limit costs: at this budget Jaén can only be reached by air — 439 kg CO₂e, in 5h 48m. Allow up to 24 hours and the train does the same journey for 64.2 kg in 24h — 7× less carbon for 18h 12m more travelling.

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 Jaén (439 kg, 11.4 h) to Izmir (689 kg, 11.6 h) buys 0.2 hours more sunshine for an extra 250 kg — 1249 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 Sheffield in September?

Izmir, Turkey, at 11.6 h. Reaching it emits 689 kg CO₂e return, travelling 7h 12m each way by air (modelled).

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

Yes. Aix-en-Provence reaches 10.8 h and is reachable by rail or ferry in 13h 18m (modelled), emitting 47.2 kg CO₂e return — though Izmir is sunnier still, if you fly.

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

689 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.
