The 10 warmest places within 15 hours of Brussels

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.

The low-carbon trade-off

The warmest place you can reach from Brussels in August within 15 hours is Kom Ombo, 36.8 °C, costing 894 kg CO₂e return. The lowest-carbon option is Düren at 4.4 kg — 203× less carbon, for 17.4 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.

By rail or ferry By air

Carbon against warmth, August, departing Brussels. Journeys of up to 15 hours each way.

What the 15-hour limit costs: at this budget Andujar can only be reached by air — 395 kg CO₂e, in 5h 36m. Allow up to 24 hours and the train does the same journey for 46.3 kg in 18h 42m — 9× less carbon for 13h 6m more travelling.

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 (612 kg, 35.9 °C) to Kom Ombo (894 kg, 36.8 °C) buys 0.9 °C more warmth for an extra 282 kg — 313 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.
