The 10 sunniest places within 15 hours of Stockholm

Ranked on sunshine in May 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 Stockholm in May within 15 hours is Gävle, 14.7 h, costing 4.7 kg CO₂e return. The lowest-carbon option is Gävle at 4.7 kg — 1× less carbon, for 0.0 hours less sunshine.

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

The same month, asked differently

May 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.
