**Official forecasts from the India Meteorological Department (IMD) and supporting model guidance indicate a minimum temperature of 27–28°C for Lucknow on August 29, 2026, during active southwest monsoon conditions.** Nighttime radiative cooling remains limited by high humidity (often 80–95%), persistent cloud cover, and scattered thunderstorms, which keep surface temperatures elevated compared to drier periods. Recent observations show night temperatures running normal to slightly above normal across Uttar Pradesh, with light-to-moderate rainfall recorded in the preceding 24 hours. Key variables that could shift the exact minimum between 25°C and 28°C include overnight cloud thickness, the timing and intensity of any thunderstorms (which can either suppress cooling or briefly lower readings via evaporative effects), and boundary-layer wind speeds. Stronger or more persistent convection would favor the lower end of the range by enhancing mixing, while clearer intervals would support readings closer to 28°C. Model consensus and official outlooks place the most likely outcome near 27–28°C, aligning with the closely matched market-implied probabilities around those levels. Updated IMD briefings and late-evening observations on August 28 will provide the final inputs before resolution.
