Recent India Meteorological Department forecasts and model consensus place Lucknow’s minimum temperature on October 17 in the low-to-mid 20s °C, with most block-level guidance showing 22–24 °C under largely clear to partly cloudy skies and light winds. This narrow band creates tight market-implied odds because small differences in overnight radiative cooling, boundary-layer humidity, or localized wind shifts can easily move the reading one or two degrees either way. Post-monsoon conditions favor rapid surface cooling once solar heating ends, yet residual moisture and variable cloud cover introduce modest uncertainty. Updated IMD briefings and final observational data on the 17th will resolve the precise value within this tight range.
