Recent India Meteorological Department forecasts for Lucknow on May 17 indicate a maximum temperature near 42°C under typical pre-monsoon clear skies, with strong solar heating and low humidity across the Ganges Plain driving daytime peaks. This aligns with historical mid-May averages of 40–42°C, though broader seasonal above-normal rainfall has produced cooler-than-expected conditions in parts of northern India, increasing the chance of readings at or below 41°C. Model consensus shows limited cloud cover or moisture incursion that could moderate intensification, while official block-level guidance places values between 41–42.2°C. Traders appear to weigh the narrow window for exceeding 42°C against these stabilizing factors ahead of the final evening observation.
