About Mausm
Last updated: 22 September 2026
Mausm provides weather forecasts and air-quality information for Indian cities in 20 languages. City pages show current conditions, hourly forecasts, seven-day forecasts and data sources.
Who operates Mausm
Mausm is operated by LabProto. LabProto is responsible for the site’s presentation, forecast calculations and corrections. Forecasts are generated automatically; they are not individually reviewed by a meteorologist.
Corrections and feedback
To report an incorrect label, translation, location or calculation, email hello@laproto.com with the page URL, the time shown and the issue. Reports can be checked against the displayed source and update time. Source readings may be revised by the provider; Mausm does not independently verify every observation.
Where the forecast comes from
Our forecasts use Open-Meteo, which combines numerical weather models from meteorological agencies. Current conditions are model estimates, not a live reading from a weather station at your address. Data is provided under CC BY 4.0; Mausm formats it into charts and plain-language summaries.
How forecast pages are produced
Each city page uses that city’s coordinates and the latest available forecast. The tomorrow, temperature and rain reports calculate their summaries, hourly windows and comparisons from the same dated forecast shown on the page. AQI reports use the air-quality sources described below. Pages are generated automatically, but unavailable values stay unavailable and older cached forecasts remain clearly labelled with their update time.
What the numbers mean
Rain percentages describe forecast precipitation probability. Daily rain chance is the maximum hourly probability for that day. Rainfall is the forecast daily total in millimetres. Rain pages separately label peak probability and maximum wind for the remaining hours. A likely-rain window groups consecutive forecast hours with probability at least 50%; it is not a guaranteed start or duration. Temperature extremes are calculated from the full day’s available hourly values, and can differ from daily model maxima and minima. Wind is in kilometres per hour. All forecast times use India Standard Time.
Hourly data does not predict exactly when rain will begin on your street. Longer-range forecasts are more uncertain. The update time is shown on every forecast; older cached data is labelled when used.
Air quality and history
Where fresh and sufficiently complete CPCB station data is available, Mausm shows Indian AQI using the highest available pollutant AQI sub-index for the selected station. Other cities use a clearly labelled CAMS / Copernicus model estimate on the US AQI scale. We require at least three valid pollutant sub-indices, including PM2.5 or PM10, and a station timestamp within six hours. Among eligible stations in the city snapshot, we select the station with the most available pollutants, breaking ties by distance to the city coordinates. This is one station, not a city-wide average. Indian categories are Good (0-50), Satisfactory (51-100), Moderate (101-200), Poor (201-300), Very poor (301-400), and Severe (401-500).
The previous 24-hour chart remains CAMS model data on the US scale, not the selected station’s history. Its categories and geographic coverage differ, so its values should not be treated as a change from the Indian station reading. Missing values stay unavailable rather than becoming zero.

Official warnings
Mausm is an independent service and is not affiliated with the India Meteorological Department. Direct IMD warning integration is not yet active. Please consult IMD for official weather warnings and severe-weather guidance.
Coverage
Mausm covers 100 Indian cities in 20 languages, with city-specific weather, tomorrow, temperature, rain and AQI reports in every supported language. Location access selects the nearest supported city, rather than generating a forecast for your exact address.
