Without flying, it is Grosseto, Italy, 11.8 h of sun a day, about 9h 48m each way by train, for about 35× less carbon (16.2 kg CO₂e return against 567 kg).

The 10 sunniest places within 15 hours of Zurich

Ranked on sunshine in April 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 Zurich in April within 15 hours is Toledo, 12.1 h, costing 329 kg CO₂e return. The lowest-carbon option is Lugano at 4.5 kg — 73× less carbon, for 2.6 hours less sunshine.

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

By rail or ferry By air

Carbon against sunshine, April, departing Zurich. Journeys of up to 15 hours each way.

What the 15-hour limit costs: at this budget Toledo can only be reached by air — 329 kg CO₂e, in 5h 12m. Allow up to 24 hours and the train does the same journey for 38.6 kg in 18h 30m — 9× less carbon for 13h 18m 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 Marseille (15.2 kg, 11.7 h) to Toledo (329 kg, 12.1 h) buys 0.4 hours more sunshine for an extra 314 kg — 785 kg of CO₂e per hour. That single step is the most expensive sunshine on the whole curve.

The same month, asked differently

April 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.

Toledo, Spain, at 12.1 h. Reaching it emits 329 kg CO₂e return, travelling 5h 12m each way by air (modelled).

Can I get somewhere sunny from Zurich in April without flying?

Yes. Marseille reaches 11.7 h and is reachable by rail or ferry in 9h 30m (modelled), emitting 15.2 kg CO₂e return — though Toledo is sunnier still, if you fly.

How much carbon does a return trip from Zurich to Toledo produce?

329 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.
