Sources & licenses

Seventeen public sources, combined and recalculated every time the site updates. Here is exactly what we use from each, under what terms.

We combine public data into new calculations — percentiles, monthly averages, seasonal patterns, distances — and write our own text around them. Where a source’s own words or photos appear, they are quoted briefly or credited under their license. Headlines from news sites and the city link back to the original articles; we don’t republish their content.

Map data © OpenStreetMap contributors, available under the Open Database License. Weather data by Open-Meteo.com (CC BY 4.0). Wildlife observations and photos © their observers on iNaturalist, used under the Creative Commons licenses they chose. Photos from Wikimedia Commons are credited individually.
