The 10 sunniest places within 15 hours of Oslo

Ranked on sunshine 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 sunshine each extra kilogram buys.

The low-carbon trade-off

The sunniest place you can reach from Oslo in July within 15 hours is Nice, 14.3 h, costing 457 kg CO₂e return. The lowest-carbon option is Karlstad at 4.9 kg — 93× less carbon, for 1.8 hours less sunshine.

Every destination here is on the efficiency frontier: nowhere else this site covers is both sunnier in July and lower in carbon. Anything a better option beats outright has been left out.

July from Oslo — 4 destinations on the frontier, 3 without flying.

Karlstad, Sweden	Rail	4.9 kg	16.7 °C	12.5 h	5.9 mm	4h 24m

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 Stockholm (12.3 kg, 13.7 h) to Nice (457 kg, 14.3 h) buys 0.6 hours more sunshine for an extra 445 kg — 741 kg of CO₂e per hour. That single step is the most expensive sunshine 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 sunniest place to go from Oslo in July?

Nice, France, at 14.3 h. Reaching it emits 457 kg CO₂e return, travelling 5h 54m each way by air (modelled).

Can I get somewhere sunny from Oslo in July without flying?

Yes. Stockholm reaches 13.7 h and is reachable by rail or ferry in 7h 24m (modelled), emitting 12.3 kg CO₂e return — though Nice is sunnier still, if you fly.

How much carbon does a return trip from Oslo to Nice produce?

457 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.
