The 10 warmest places within 15 hours of Rome

Ranked on warmth in December 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 warmth each extra kilogram buys.

The low-carbon trade-off

The warmest place you can reach from Rome in December within 15 hours is Sharm el-Sheikh, 20.4 °C, costing 632 kg CO₂e return. The lowest-carbon option is Grosseto at 4.4 kg — 144× less carbon, for 12.3 degrees less warmth.

Every destination here is on the efficiency frontier: nowhere else this site covers is both warmer in December 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 San Pawl il-Bahar (171 kg, 16.0 °C) to Alexandria (491 kg, 16.8 °C) buys 0.8 °C more warmth for an extra 319 kg — 399 kg of CO₂e per degree. That single step is the most expensive warmth on the whole curve.

The pick of them

The same month, asked differently

December 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.
