The 10 sunniest places within 15 hours of Lisbon

Ranked on sunshine in June 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 Lisbon in June within 15 hours is Turku, 15.7 h, costing 818 kg CO₂e return. The lowest-carbon option is Figueira da Foz Municipality at 4.7 kg — 174× less carbon, for 3.2 hours less sunshine.

Every destination here is on the efficiency frontier: nowhere else this site covers is both sunnier in June 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 Bragança (11.8 kg, 13.5 h) to Aalborg (620 kg, 14.3 h) buys 0.8 hours more sunshine for an extra 609 kg — 761 kg of CO₂e per hour. That single step is the most expensive sunshine on the whole curve.

The same month, asked differently

June 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.

Can I get somewhere sunny from Lisbon in June without flying?

Yes. Bragança reaches 13.5 h and is reachable by rail or ferry in 7h 18m (modelled), emitting 11.8 kg CO₂e return — though Turku is sunnier still, if you fly.

How much carbon does a return trip from Lisbon to Turku produce?

818 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.
