The 10 coolest places within 15 hours of Lisbon

Ranked on relief from the heat in March 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 relief from the heat each extra kilogram buys.

The low-carbon trade-off

The coolest place you can reach from Lisbon in March within 15 hours is Rovaniemi, 19.8 °C cooler, costing 885 kg CO₂e return. The lowest-carbon option is Castelo Branco at 5.5 kg — 161× less carbon, for 17.4 degrees less relief from the heat.

Every destination here is on the efficiency frontier: nowhere else this site covers is both cooler in March 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 Guarda (7.6 kg, 6.5 °C cooler) to Rhondda (379 kg, 7.8 °C cooler) buys 1.3 °C more relief from the heat for an extra 371 kg — 285 kg of CO₂e per degree. That single step is the most expensive relief from the heat on the whole curve.

The pick of them

The same month, asked differently

March 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.
