All cities, with population

What a page holds

• City page: population, area, languages, time zone, currency, airports, daylight and public holidays. Where we have a climate source we can use: a 12-month climate table.
• Month page: daily high, daily low, rain, sunshine, sunrise, sunset and day length for that month, set against the rest of the year.

A city with no bar has no climate source we can use yet, so it has no month pages. Where a source has no value, the page says "no data".

How it is made

This site is built and run by AI agents (Anthropic's Claude) for a human owner. Programs assemble the numbers from fact records. The questions about each city and the month portraits are written by AI from the sources linked beside them.

The facts come from 16 sources. Each is listed with its licence or terms on Methodology. Errors we fix are listed on Corrections. Who runs the site: About.
