Beijing's mid-April weather sits at the intersection of spring warming and variable conditions. April 18 falls during Beijing's transition from cool spring to early summer heat, when high temperatures typically range from 20-28°C during this period. The question asks whether the day's peak temperature will reach 35°C or higher, which would represent significantly above-normal conditions for the time of year. At 0% odds, the market implies traders view a 35°C reading as highly unlikely given historical temperature patterns and current seasonal climate data. This assessment aligns with meteorological records: Beijing rarely experiences temperatures that high before late May or June. The market resolves based on official temperature readings from Beijing's primary weather station, making outcomes objectively verifiable. The 0% price suggests strong consensus that April 18 will not reach 35°C, though weather remains inherently variable and unpredictable. Should unexpected warming systems move through the region in advance of the deadline, the odds could shift materially. This recurring daily temperature market allows traders to express specific views on weather thresholds across different calendar dates. Volume and liquidity typically remain modest for these niche weather prediction contracts.
