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 Gdansk (16.4 kg, 17.8 °C) to Nyiregyhaza (324 kg, 19.2 °C) buys 1.4 °C more warmth for an extra 307 kg — 220 kg of CO₂e per degree. That single step is the most expensive warmth on the whole curve.
The pick of them
If you'd rather have sunshine than heat
September answers differently depending on what you're after. The sunniest destinations from Stockholm in September are a different list — the brightest places are not always the hottest, and in winter the difference is large.
