The 10 coolest places within 15 hours of Nottingham

Ranked on relief from the heat 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 relief from the heat each extra kilogram buys.

The low-carbon trade-off

The coolest place you can reach from Nottingham in May within 15 hours is Reykjavik, 6.4 °C cooler, costing 431 kg CO₂e return. The lowest-carbon option is La Chaux-de-Fonds at 34.8 kg — 12× less carbon, for 4.2 degrees less relief from the heat.

Every destination here is on the efficiency frontier: nowhere else this site covers is both cooler 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 La Chaux-de-Fonds (34.8 kg, 2.2 °C cooler) to Östersund (367 kg, 3.1 °C cooler) buys 0.9 °C more relief from the heat for an extra 332 kg — 369 kg of CO₂e per degree. That single step is the most expensive relief from the heat on the whole curve.

The same month, asked differently

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.

Reykjavik, Iceland, at 6.4 °C cooler. Reaching it emits 431 kg CO₂e return, travelling 5h 48m each way by air (modelled).

Can I get somewhere cool from Nottingham in May without flying?

Yes. La Chaux-de-Fonds reaches 2.2 °C cooler and is reachable by rail or ferry in 13h 36m (modelled), emitting 34.8 kg CO₂e return — though Reykjavik is cooler still, if you fly.

How much carbon does a return trip from Nottingham to Reykjavik produce?

431 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.
