The 10 warmest places within 15 hours of Madrid

Ranked on warmth in August 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.

≈ is the model's estimate (air times include getting to and through the airport); ✓ is a rail journey checked against a real timetable, with the date it was checked. Temperatures are historical daily means for 2023–2024, averaged across day and night, so afternoons run warmer.

The low-carbon trade-off

The warmest place you can reach from Madrid in August within 15 hours is Kom Ombo, 36.8 °C, costing 897 kg CO₂e return. The lowest-carbon option is Ciudad Real at 4.7 kg — 191× less carbon, for 8.0 degrees less warmth.

Every destination here is on the efficiency frontier: nowhere else this site covers is both warmer in August 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 Zagora (286 kg, 35.9 °C) to Kom Ombo (897 kg, 36.8 °C) buys 0.9 °C more warmth for an extra 611 kg — 678 kg of CO₂e per degree. That single step is the most expensive warmth on the whole curve.

The same month, asked differently

August 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.
