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 Taroudant (599 kg, 20.9 °C) to Akhmim (943 kg, 21.7 °C) buys 0.8 °C more warmth for an extra 344 kg — 430 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
March answers differently depending on what you're after. The sunniest destinations from Cardiff in March are a different list — the brightest places are not always the hottest, and in winter the difference is large.
