The low-carbon trade-off
The sunniest place you can reach from Oslo in May within 15 hours is Sundsvall, 15.1 h, costing 13.2 kg CO₂e return. The lowest-carbon option is Karlstad at 4.9 kg — 3× less carbon, for 0.8 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.
By rail or ferry By air
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.
The pick of them
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.
