The 10 sunniest places within 15 hours of Bristol

Ranked on sunshine 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 sunshine each extra kilogram buys.

The low-carbon trade-off

The sunniest place you can reach from Bristol in May within 15 hours is Gävle, 14.7 h, costing 399 kg CO₂e return. The lowest-carbon option is Hemel Hempstead at 12.2 kg — 33× less carbon, for 5.0 hours less sunshine.

Every destination here is on the efficiency frontier: nowhere else this site covers is both sunnier 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 Plymouth (13.0 kg, 12.0 h) to Odense (242 kg, 12.6 h) buys 0.6 hours more sunshine for an extra 229 kg — 382 kg of CO₂e per hour. That single step is the most expensive sunshine 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.
