Will this summer break records? Since 1981 your city has changed: heat, rain, sun, air. Real NASA and Copernicus data, free. Find your city.
You remember summers differently. The heat waves that used to be exceptional now feel routine. The winters that used to be cold barely freeze anymore. Climio shows you the data behind that feeling, for your city, from 1981 to today.
Not a weather forecast. A climate history. Your city.
Backed by 40+ years of NASA and Copernicus data, Climio covers temperatures, air quality, precipitation and sunshine for any city in the world.
TEMPERATURE TRENDS
• Temperature history from 1981 to today for any city on Earth
• See exactly how many degrees your city has shifted over the decades
• Year-over-year charts reveal how each season is changing over time
SEASONAL INSIGHTS
• Spring, Summer, Autumn and Winter trends side by side
• See which season is warming fastest in your city
• Monthly hottest and coldest records for every year in your range
AIR QUALITY
You can't see PM2.5. You can't smell NO₂. But they affect your lungs every day. Climio surfaces the air quality data that health agencies monitor, and shows whether your city is getting cleaner or more polluted, with WHO thresholds always visible.
• PM2.5, PM10, NO₂ and O₃ levels from Copernicus CAMS
• WHO guideline thresholds shown on every chart
• Track whether air pollution is improving or worsening over time
CITY COMPARISON
Thinking of moving? Choosing between two cities goes beyond cost of living. Climio puts them side by side: temperature trends, air quality, rainfall, sunshine hours. Decide based on data, not assumptions.
• Compare any two cities: temperature, air quality, precipitation and sunshine
• Full pollutant breakdown: PM2.5, PM10, NO₂, O₃ side by side
• Perfect for deciding where to live, work or travel
PRECIPITATION & SUNSHINE
• Historical rainfall trends to understand drought and flood patterns over decades
• Annual sunshine hours to compare climates beyond temperature alone
PDF EXPORT
• Export a complete climate report with all charts, ready to share, present or save
