About
Weather data for 30 prominent cities in Sri Lanka is available, covering the period from 1 January 2010, to 1 January 2023. This collection offers a wide array of meteorological parameters, enabling detailed analysis and insights into the climate patterns of different regions across the country. The data was gathered using a Python script from sources including Open-Meteo and simplemaps and has been pre-processed to ensure it is clean and readable.
Columns
