The 10 warmest places within 15 hours of Paris

Ranked on warmth in July 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 Paris in July within 15 hours is Nefta, 36.0 °C, costing 434 kg CO₂e return. The lowest-carbon option is Dieppe at 4.4 kg — 99× less carbon, for 18.0 degrees less warmth.

Every destination here is on the efficiency frontier: nowhere else this site covers is both warmer in July 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 Córdoba (39.7 kg, 30.7 °C) to Kairouan (401 kg, 32.8 °C) buys 2.1 °C more warmth for an extra 362 kg — 172 kg of CO₂e per degree. That single step is the most expensive warmth on the whole curve.

The same month, asked differently

July 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.

Questions

Where is the warmest place to go from Paris in July?

Nefta, Tunisia, at 36.0 °C. Reaching it emits 434 kg CO₂e return, travelling 5h 48m each way by air (modelled).

Can I get somewhere warm from Paris in July without flying?

Yes. Córdoba reaches 30.7 °C and is reachable by rail or ferry in 14h 36m (modelled), emitting 39.7 kg CO₂e return — though Nefta is warmer still, if you fly.

How much carbon does a return trip from Paris to Nefta produce?

434 kg CO₂e for one person, return, by air. That uses the UK Government's 2026 conversion factors, including radiative forcing for flights.

Carbon uses UK Government (DESNZ/DEFRA) 2026 conversion factors applied to great-circle distance, with radiative forcing included for flights. Rail journey times are modelled estimates, not timetabled services. Full method · download the data.
