Free 30-year historical weather forecasts for 473+ destinations, plus embeddable widgets for planning trips, weddings and events.
30YearWeather provides long-range historical weather forecasts built from 30 years of NASA satellite data (NASA POWER Project, 1991-2021), supplemented by Open-Meteo and ERA5 sources. Rather than short-range meteorological predictions, the site shows probability-based weather patterns for a given date and location, covering 473+ destinations worldwide and 365 days per city, aimed at travel planning, weddings, photography, and outdoor events months in advance.
Beyond the core forecast tool, 30YearWeather offers free embeddable weather widgets for travel blogs and websites (iframe-based, no coding or registration required) with configurable size, layout, theme, and content, plus an official free WordPress plugin (Gutenberg blocks and shortcodes). A location comparison tool lets users evaluate weather across multiple destinations side by side.
