The 10 warmest places within 15 hours of Lisbon
Ranked on warmth in May 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 Lisbon in May within 15 hours is Edfu, 31.4 °C, costing 986 kg CO₂e return. The lowest-carbon option is Figueira da Foz Municipality at 4.7 kg — 210× less carbon, for 14.7 degrees less warmth.
Every destination here is on the efficiency frontier: nowhere else this site covers is both warmer in May 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 (247 kg, 27.6 °C) to Assiut (922 kg, 29.0 °C) buys 1.4 °C more warmth for an extra 676 kg — 483 kg of CO₂e per degree. That single step is the most expensive warmth on the whole curve.

May 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.

Edfu, Egypt, at 31.4 °C. Reaching it emits 986 kg CO₂e return, travelling 9h 6m each way by air (modelled).
Can I get somewhere warm from Lisbon in May without flying?
Yes. Seville reaches 21.7 °C and is reachable by rail or ferry in 6h 30m (modelled), emitting 9.3 kg CO₂e return — though Edfu is warmer still, if you fly.
How much carbon does a return trip from Lisbon to Edfu produce?
986 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.
