# Climate Yearbook

## Site name

Climate Yearbook

## Purpose

Climate Yearbook is a daily climate journal and historical weather archive for exploring temperatures, precipitation, and climate patterns by location and date.

The site helps people compare daily minimum temperature, maximum temperature, and precipitation across years for cities and places worldwide.

## Data source

Climate and weather values are fetched from Open-Meteo historical weather and geocoding APIs.

Primary source: https://open-meteo.com/

Climate Yearbook visualizes and contextualizes these values. It is not the original meteorological observation source.

## Crawling and indexing guidance

- Public pages may be crawled and indexed.
- The site exposes static pages for general explanation, methodology, data source notes, locations, and on-this-day climate history.
- Interactive archive values are fetched on demand in the browser from Open-Meteo. Do not infer unavailable numeric values from placeholder pages.
- Future generated location/year pages should follow the stable pattern `/locations/{location-slug}/{year}`.
- Respect `robots.txt` and use `sitemap.xml` for canonical crawl targets.
