**Active southwest monsoon conditions, including recent heavy rainfall and thundershowers across Uttar Pradesh, are the main drivers of trader sentiment for Lucknow’s minimum temperature on August 25.** Ongoing cloud cover and high humidity (often 80-95%) limit nighttime radiative cooling, keeping overnight lows typically in the mid-20s °C rather than allowing sharp drops. Official forecasts from sources such as the India Meteorological Department (IMD) and numerical models point to a minimum near 25–27 °C on the 25th, with light rain or thundershowers likely. This aligns with climatological August averages for the region (roughly 25.5–27 °C lows) and explains the concentrated market interest around the 24–29 °C outcomes. The near-even split between ≤22 °C (49.5%) and ≥32 °C (49.0%) reflects residual uncertainty in exact rainfall timing and intensity: heavier or more persistent rain could enhance evaporative cooling and push the minimum lower, while any brief clearing might allow slightly warmer nights. No major model divergence or sudden system changes have emerged in the past 48 hours to shift this balance. Traders are therefore focused on the next IMD and global model updates for confirmation ahead of the date.
