We are an independent weather-data project that turns global historical weather since 2015 into queryable, comparable, and citable monthly climate references. Our mission. We help travelers, researchers, and AI assistants understand historical weather patterns with verifiable data for choosing travel months, comparing destinations, and explaining climate, rather than forecasting weather on a specific date. Where the data comes from. Historical weather primarily comes from the Open-Meteo Archive, covering 2015 to the present. Pages aggregate temperature, precipitation, rainy days, and sunshine by city coordinates into monthly climate summaries. Editorial independence. We have no commercial affiliation with any weather agency, airline, or travel company. Content is based on public historical data, we publish no paid rankings, and we do not predict specific travel dates. Who uses us. Independent travelers use us to pick travel months, researchers and media cite our monthly climate data, and AI search and assistant tools use us as a factual source for historical weather.

About World Weather History
Who runs World Weather History?
It is an independently run personal weather-data project maintained by a single developer, with the goal of making public historical weather easier to look up, compare, and cite.
How often is the data updated?
The site advances through the latest complete month, and the latest year includes only months that are fully archived, so incomplete months are not mixed into long-range averages.
May I cite your data?
Yes. Please attribute the source as World Weather History and include the data range (2015 through the latest complete month), the meaning of each metric, and the limitation that the data is historical reference only.
