The 10 warmest places within 15 hours of Glasgow

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 Glasgow in July within 15 hours is Nefta, 36.0 °C, costing 658 kg CO₂e return. The lowest-carbon option is Whitehaven at 12.3 kg — 54× less carbon, for 21.4 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.

By rail or ferry By air

Carbon against warmth, July, departing Glasgow. Journeys of up to 15 hours each way.

What the 15-hour limit costs: at this budget Aranjuez can only be reached by air — 443 kg CO₂e, in 5h 48m. Allow up to 24 hours and the train does the same journey for 83.1 kg in 23h — 5× less carbon for 17h 12m 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 Avignon (71.7 kg, 25.4 °C) to Zaragoza (402 kg, 27.1 °C) buys 1.7 °C more warmth for an extra 330 kg — 194 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.

Nefta, Tunisia, at 36.0 °C. Reaching it emits 658 kg CO₂e return, travelling 7h each way by air (modelled).

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

Yes. Avignon reaches 25.4 °C and is reachable by rail or ferry in 14h 24m (modelled), emitting 71.7 kg CO₂e return — though Nefta is warmer still, if you fly.

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

658 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.
