This prediction market focuses on forecasting the maximum temperature recorded at Warsaw Chopin Airport on March 26, 2026. The market resolves to a specific temperature range based on data from Wunderground's historical records for the EPWA station. This type of market belongs to the growing category of climate prediction markets, where participants bet on specific meteorological outcomes rather than traditional financial instruments. Interest stems from both meteorological enthusiasts tracking seasonal weather patterns and financial participants seeking to profit from accurate forecasts of measurable events. The specific date of March 26 places the prediction in the early spring period for Warsaw, a time known for significant temperature variability as winter transitions to warmer conditions. The use of a single, authoritative weather station (EPWA) ensures a clear, unambiguous resolution source, which is critical for prediction market integrity. These markets have gained attention as tools for aggregating dispersed information about future events, with weather predictions serving as a test case due to their objective, verifiable nature. Participants analyze long-term climate data, recent seasonal forecasts, and specific meteorological models to inform their positions on the likely high temperature for that day.

Historical Context

Warsaw's climate is classified as humid continental, characterized by cold winters and warm summers, with a significant transition period in spring. The city's official meteorological records date back to the late 18th century, with consistent modern records from the Okęcie district (now Chopin Airport location) available since the mid-20th century. Historically, March is a month of rapid change. The average daily maximum temperature for March in Warsaw, based on the 1991-2020 reference period, is approximately 6.5°C (43.7°F). However, daily extremes vary widely. For instance, on March 26, 1968, the temperature reached 20.0°C (68.0°F), an exceptional warm spell for the date. In contrast, March 26, 1975, saw a high of only -0.8°C (30.6°F), with snow still on the ground. The decade from 2011 to 2020 was the warmest on record for Poland, with a noticeable trend toward earlier spring warmth. This warming trend, attributed to anthropogenic climate change, has increased the probability of unusually warm March days in recent years compared to the mid-20th century. The specific location of the Chopin Airport station, on the southwestern outskirts of the city, can be influenced by urban heat island effects, though these are less pronounced in early spring than in summer.
