How to read this
- Each value is the country-wide monthly average compared with the same calendar month averaged over 1991–2020.
- Nothing is adjusted for the long-term warming trend, so recent years show more red. That is the trend, not an error.
- Rainfall is shown as a percentage of normal. Months that are normally almost dry (under 0.2 mm a day) are left blank, because a percentage of almost nothing is meaningless.
- Country averages hide local extremes: a heatwave in one region can vanish in a large country's average.
