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 each page from a fact record. No fact comes from a language model.

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.
