Mosam (मौसम) Meaning: Why the Word Is Trending and How It Leads to IMD's Live Weather Forecasts

Mosam is the Roman-script spelling of the Hindi/Urdu word मौसम (mausam), meaning weather or season. Google Trends India recorded the term as a rising query over the past 12 months, with about 40% growth as observed on 17 September 2026 — though the normalized interest score of 1 out of 100 shows this is modest curiosity, not a mass event. People typing 'mosam' into Google usually want one of two things: the meaning of the word, or today's weather forecast. Both answers are below.

What does 'mosam' mean?

In Hindi and Urdu, मौसम covers both 'weather' — the day-to-day state of the atmosphere — and 'season', as in mausam-e-bahaar (spring) or the monsoon season. The word appears constantly in everyday speech, film songs and poetry, which is why it remains one of the most commonly transliterated Hindi words in Indian search. When someone searches 'aaj ka mosam', they almost always want a local forecast rather than a dictionary definition.

From a word to a website: IMD's 'Mausam' branding

The word has an official home. The India Meteorological Department (IMD) runs its public portal at mausam.imd.gov.in, and its headquarters is literally named Mausam Bhavan on Lodi Road, New Delhi. IMD, formed on 15 January 1875, is India's principal agency for weather observations, forecasting and seismology under the Ministry of Earth Sciences. It is also one of six Regional Specialised Meteorological Centres of the World Meteorological Organisation, responsible for forecasting and naming tropical cyclones in the North Indian Ocean, including the Bay of Bengal and the Arabian Sea.

What you can check on the Mausam portal

For anyone whose 'mosam' search is really a forecast request, the IMD portal offers:

• District-wise and station-wise nowcast warnings and five-day rainfall forecasts
• Current city weather — for example, on 21 September 2026 the portal showed Delhi at 33.2°C with haze, Mumbai at 30.0°C and Chennai at 25.0°C under overcast skies
• Flash flood bulletins, heat wave guidance, thunderstorm and lightning forecasts
• Specialised products such as agromet advisories for farmers, highway and railway forecasts, and interactive cyclone tracking

Live alert: Bay of Bengal depression watch, 21 September 2026

The timing of the trend is notable. In a press release dated 21 September 2026, IMD said a well-marked low-pressure area over the northwest Bay of Bengal was 'very likely to become depression and deep depression during the next 48 hours.' This is a forecast, not a confirmed cyclone — systems at this stage can intensify, weaken or change track. Residents of coastal Odisha, West Bengal and adjoining areas should follow IMD's updates rather than rely on a single bulletin.

Why the trend needs context

Google Trends data confirms rising search interest in 'mosam', not the reason behind it. Intent could range from checking the rain before a commute to looking up song lyrics or poetry. What the data does show is that a growing number of Indians type Hindi words in Roman script when searching — and in this case, that habit leads directly to one of the country's oldest scientific institutions and its free, multilingual weather services.
