Ongoing heatwave conditions across northern India, with recent Lucknow maxima near 41°C and IMD forecasts pointing to 40–42°C amid above-normal temperatures, drive the market's clustering around 39–41°C. Key variables include the timing of monsoon advance, which could introduce cloud cover and reduce peaks, versus persistent clear skies and dry westerlies sustaining highs; local factors like humidity, wind speed, and urban heat island effects add variability. Short-term model runs from IMD and global ensembles show divergence on exact intensification, while historical June baselines around 37°C highlight the current anomaly. Traders weigh these against potential rapid shifts from updated 48-hour forecasts ahead of June 28 resolution.
