About Mausam Online
Mausam Online is a free, fast, and mobile-first weather service designed for people in India, Pakistan, and Bangladesh. We provide real-time weather forecasts, hourly updates, 7-day outlook, and air quality data for over 800 cities across South Asia.
Our Mission
Weather affects daily life — from commuting and farming to health and travel planning. Our goal is to make accurate, up-to-date weather information accessible to everyone, especially on low-cost mobile devices with limited internet connectivity.
Data Sources
All weather data is sourced from Open-Meteo, which aggregates data from global meteorological agencies including ECMWF (European Centre for Medium-Range Weather Forecasts). Air quality is reported on each country’s own national index — the CPCB National AQI for India, Pakistan, Bangladesh, Nepal and Sri Lanka, the US EPA AQI elsewhere — computed from 24-hour means, with the PM2.5 and PM10 readings shown alongside.
Technology
Mausam Online is built as a Progressive Web App (PWA) using modern web technologies. The site is statically generated for maximum speed, uses JavaScript for interactive forecasts, and can display previously cached data offline. We support English, Hindi, Bengali, Urdu and Tamil; available languages vary by region.
Coverage
We cover cities across 35 Indian states and union territories, 7 Pakistani provinces, and 8 Bangladeshi divisions. Each city page includes current conditions, hourly forecast, 7-day forecast, and air quality index.

The network itself: which sites belong to it, and how they fund an animal sanctuary. In English.
These are listed here rather than in the footer of every page. They are separate services for separate audiences, and a reader in India has no use for a Czech forecast.
