This set of markets assesses whether measurable rainfall will occur on a specific date in various U.S. cities. Each market focuses on a different location, allowing participants to evaluate regional weather forecasts and conditions for August 12, 2026.
Each market evaluates whether measurable precipitation occurs on August 12, 2026, in a specified U.S. city. For a market to resolve as 'Yes,' the total precipitation recorded at the official weather station for that city must exceed zero inches. 'Trace' amounts and missing data are counted as zero inches and do not satisfy the condition. All outcomes are determined using data from the Weather Company, accessed via the provided URL, ensuring consistency across all markets. Participants should note that while third-party weather services may offer forecasts, the official data source linked in the rules is the sole authority for resolution.
