Official IMD forecasts for Lucknow on October 13 indicate mainly clear skies with a minimum temperature near 22°C, following an observed low of 21.8°C the prior night. Post-monsoon conditions favor strong nocturnal radiative cooling under low humidity and light winds, though urban heat island effects and any thin high clouds could moderate the drop by 1–2°C. The tightly clustered market-implied odds around 20–23°C reflect uncertainty in exact overnight minimums, as small shifts in cloud cover, boundary-layer mixing, or local wind patterns can alter the final reading recorded by official stations. Updated model guidance and evening observations will refine these probabilities ahead of resolution.
