50 Cities, 15 Days: The Urban Atmosphere Dataset

UrbanClimate 2026 is a curated collection of daily meteorological observations from 50 of the world’s most significant metropolitan hubs. Covering the first half of April 2026, this dataset provides a high-resolution "pulse check" of the global urban atmosphere.

From the humid streets of Lagos to the temperate sprawl of Tokyo, this data captures the intersection of geography and climate. It is designed for data scientists, meteorology enthusiasts, and urban planners looking to explore patterns in temperature fluctuations, precipitation probabilities, and celestial timing.

Weather data is often siloed by country or station. This dataset consolidates information from 50 unique cities across all inhabited continents, providing a standardized format for cross-border climate analysis. By focusing on a specific 15-day window, users can perform synchronized comparisons of how different global regions transitioned into the second quarter of 2026.

Key Features:

Global Coverage: Includes major capitals and financial centers (New York, Mumbai, London, São Paulo).

Rich Metrics: Beyond temperature, it includes specialized indices like the Heat Index, UV Index, and Moon Phases.

Clean Geometry: Includes Latitude and Longitude for easy geospatial mapping and visualization.
