**Persistent heavy monsoon rainfall and extensive cloud cover are suppressing daytime heating in Lucknow, driving trader consensus toward a maximum temperature of 24–25°C on September 26.** Official India Meteorological Department forecasts project a high near 25°C (with some guidance citing 24°C) amid thunderstorms, gusty winds, and over 60 mm of expected rain that limits solar insolation and maintains high humidity near 90%. This aligns with recent observations of sharply below-normal maxima (around 24°C on September 25, departures exceeding –9°C). Numerical weather models show broad agreement on these conditions through the 26th, with limited scope for brief clearing that could push readings to 26°C or higher. Updated IMD briefings and model runs on the 26th will provide the final resolution data.
