Official India Meteorological Department observations and forecasts establish the primary driver behind the market's overwhelming 23°C consensus, with Lucknow Airport recording a 21.8°C overnight minimum and models projecting a daily low near 23°C under mainly clear skies and light winds. Post-monsoon subsidence and typical October climatology—where average minima hover around 19–20°C but recent departures run slightly above normal—support this positioning, as stable high pressure limits further cooling. Trader sentiment reflects high confidence in the IMD's 33/23°C outlook, with minimal model spread evident in current guidance. Only a sharp, unforecasted nocturnal drop or station-specific measurement variance could realistically shift the outcome below 22°C before resolution.
