Delhi weather today: forecast, observation and warning are different
Understand IMD observations, forecasts and warning validity before interpreting a Delhi weather bulletin.
For Delhi weather, check the station, observation time, forecast validity and district warning separately. A measured temperature, a future forecast and a nowcast answer different questions.
Why this query needs careful timestamps
Delhi weather and weather Delhi appeared on Google Trends India’s original past-24-hours page observed on 12 October 2026. This article answers how to read the official information. It does not substitute yesterday’s measurement for today’s temperature or claim a current alert without checking its validity.
Three different products
IMD’s official API documentation separates current-weather observations, city forecasts, district warnings and nowcasts. Its current-weather fields include station, observation date and observation time; that time is specified in UTC. City forecasts distinguish recorded maximum/minimum temperatures from forecast maximum/minimum values.
The past-24-hours rainfall field in the city forecast is defined from 08:30 IST on the previous day to 08:30 IST on the current day. That is a measurement window, not a prediction of how much rain will fall during the next 24 hours. Check which field a website is displaying before interpreting its number.
Read the warning, not just its colour
The nowcast documentation supplies a warning message, issue time and valid-until time. Its categories include rain, thunderstorms and lightning. The district-warning product also has separate dates and day-specific warning fields. Read the location and hazard text alongside the graphic.
A useful habit is to write a small note containing the district or station, issue time, validity and weather hazard. A cropped coloured map can lose all four. Do not assume that an alert for one district covers every location described casually as Delhi NCR.
What to check before leaving home
Start at the official IMD portal and follow its city forecast, district warning or nowcast links according to your question. A commute happening soon needs a different time window from an outdoor event several days away. Recheck the relevant bulletin close to departure rather than relying on a forwarded morning screenshot.
At research time, IMD’s homepage displayed an 11 October 2026 press-release link mentioning isolated heavy rain over Haryana, Chandigarh and Delhi on 11 October. Its explicit date must be preserved: that statement alone is not a verified forecast for 12 October. This is why dated bulletin text is more useful than a headline with the word today added.

Frequently asked questions
Is observed temperature the forecast maximum?
No. IMD documents measured observations and forecast maximum/minimum temperatures as different fields.
Can yesterday’s Delhi warning be called today’s warning?
Only a bulletin whose stated validity includes today can establish that; check the original issue and validity dates.
