What this can't tell you

A capital is one city, not its country, and one grid point of a weather reanalysis, not a thermometer.
The record starts in 1981, so 'much warmer than normal' means the top tenth of about 45 years.
55 of the registry's countries and territories have no capital in the dataset.

How the answer is decided

Each capital's month is ranked against the same month in every year since 1981; the words follow NOAA's convention.
