Recent heavy rainfall across Uttar Pradesh, including over 100 mm in parts of Lucknow on September 25–26, has suppressed daytime maxima to the mid-20s Celsius, with persistent cloud cover and high humidity limiting solar heating. As the system weakens and partly cloudy conditions return on September 28, models from the India Meteorological Department and international guidance indicate a rebound to a maximum near 29–30 °C under light westerly winds. Market-implied odds cluster tightly on these values because forecast spreads remain narrow, with only modest model disagreement on exact peak timing and moisture retention. Historical September averages near 34 °C provide context, yet the recent cool anomaly keeps probabilities for 31 °C or higher low. Official IMD updates and real-time observations will resolve the market.
