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 Tozeur (470 kg, 29.4 °C) to Al Fayyum (677 kg, 30.3 °C) buys 0.9 °C more warmth for an extra 206 kg — 229 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 Prague in September are a different list — the brightest places are not always the hottest, and in winter the difference is large.
