Ongoing southwest monsoon activity, with widespread cloud cover and intermittent thundershowers over Uttar Pradesh, is the main driver keeping Lucknow's projected maximum temperatures clustered around 29–31°C for August 6. Official India Meteorological Department guidance and short-range models indicate overcast skies and light-to-moderate rainfall that limit daytime heating and evaporative cooling, while humidity near 90% further moderates peaks. Historical August climatology shows similar suppressed highs during active monsoon spells, and current ensemble guidance shows only modest day-to-day variability tied to exact rainfall timing and steering winds. With market-implied odds nearly even across 29°C, 30°C, and 31°C, traders are weighting the latest model consensus on convective coverage and any last-minute shifts in the monsoon trough position.
