Lucknow is the capital of Uttar Pradesh in North India, home to over 3 million residents. April marks the transition from spring to early summer, typically one of the hottest months in the region. A temperature threshold of 39°C (102°F) represents typical late-spring heat for the area, well within the range of conditions experienced during this season. This market resolves based on the highest temperature recorded in Lucknow on April 20, 2026, as officially measured by standard weather stations. With current YES odds at just 5%, the market is pricing in a very low probability of temperatures staying at or below 39°C, implying widespread expectation of hotter conditions. This reflects historical climate patterns: Lucknow regularly experiences temperatures in the 40-45°C range during mid-April. The market ends at midnight UTC on April 20, giving a tight 24-hour window for final resolution. The low YES odds suggest traders expect the daily high to exceed 39°C, placing confidence in above-threshold temperatures for the date.
