Shanghai in mid-April experiences spring weather with typical daily highs between 15°C and 22°C. The market asks whether the highest temperature on April 20 will be exactly 13°C, a cooler-than-normal outcome that would require unusual meteorological conditions. The current 0% YES odds reflect extremely low probability assigned by traders to this precise temperature threshold. Weather prediction markets depend on official data from Shanghai's meteorological network, ensuring transparent and verifiable resolution. A high of exactly 13°C would represent an unusually cool day for late April in Shanghai, possibly resulting from a strong cold air mass or persistent rainfall. At current odds, the market consensus suggests other temperature ranges are vastly more likely. The specificity of weather markets—targeting exact temperatures rather than ranges—creates naturally low probabilities for any single outcome, as multiple temperature values are possible. This daily temperature market is part of recurring weather trading opportunities, allowing traders to express views on specific meteorological outcomes. The liquidity pool suggests consistent interest in Shanghai's daily weather prediction markets.
