Where would you live better? Freely compare the climate of any two cities worldwide.
Method
Type any two cities and confirm the right place in the search results.
For each coordinate, we request the NASA POWER 1991–2020 climatology without mixing it with a forecast.
We compare 12 months of highs, lows, rain, humidity and solar radiation and create a reproducible CSV.
Your inputs
Search by city and country. If names repeat, choose the right location before comparing.
Result
NASA POWER monthly climatologies for 1991–2020. Place geocoding by OpenStreetMap Nominatim.
Example retrieved from NASA POWER on 24 September 2026 for the displayed coordinates and 1991–2020 period. Download the original responses and the twelve-month CSV. It does not describe current weather or every neighbourhood.

Similarity averages twelve monthly scores: temperature 45%, rainfall 30%, humidity 15% and solar radiation 10%. These editorial weights measure neither comfort nor the probability of rain. Each difference is divided by its scale and bounded between 0 and 1; high and low temperatures have equal weight within their component.
