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 1,000 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 data comes from the European AQI standard with PM2.5 and PM10 measurements.

Technology

Mausam Online is built as a Progressive Web App (PWA) using modern web technologies. The site is statically generated for maximum speed, uses minimal JavaScript (under 7KB), and works offline with cached data. We support English and Hindi, with more languages planned.

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.
