Warsaw experiences variable spring weather conditions in mid-April. The city's highest daily temperature on April 20, 2026, could range anywhere from near freezing to mild spring conditions depending on atmospheric pressure systems and seasonal patterns. This prediction market resolves based on the exact high temperature recorded for that specific date, requiring verified meteorological data from official sources. A daily high of exactly 8°C would represent typical cool but seasonally appropriate spring weather for the region, neither unusually cold nor warm. Currently trading at 0% odds, the market indicates extremely low probability that the highest temperature will reach this precise value. Such narrow precision requirements typically show low certainty in markets unless multiple independent weather forecasts converge on the exact outcome. The 0% odds suggest traders believe the actual high will deviate meaningfully from 8°C in either direction. Resolution depends on verified temperature data from Warsaw's official weather monitoring station. Historical April 20 highs in Warsaw typically range from about 5°C to 20°C, making any single-degree specific target inherently a low-probability event. These granular weather markets serve as tools for traders seeking precision climate outcomes.
