Official IMD forecasts for Lucknow on August 22 project a minimum temperature near 26–28°C under generally cloudy to overcast skies with spells of rain or thundershowers amid active southwest monsoon conditions. Persistent cloud cover limits nocturnal radiative cooling, elevating overnight lows compared to clearer periods, while high humidity and scattered precipitation further moderate temperatures. Recent observations show minimums near 25–27°C, aligning with seasonal monsoon norms. Model consensus supports this range, though minor variations in rain timing or intensity could shift the exact low by 1–2°C. Traders price 25–28°C outcomes highest because these thresholds best match current guidance, with lower probabilities assigned to outliers reflecting forecast uncertainty and typical local microclimate effects.
