This set of markets assesses the likelihood of rainfall occurring in various major U.S. cities on a specific date in August 2026. Each market focuses on a different location, allowing participants to evaluate regional weather forecasts and conditions for that day.
Each market evaluates whether measurable rainfall will occur at a specified weather station in a particular U.S. city on August 14, 2026. For a market to resolve as 'Yes,' the total precipitation recorded at the designated station must exceed zero inches. 'Trace' amounts of rain and any missing data are counted as zero inches and therefore do not satisfy the condition for a 'Yes' outcome. All markets use data from the Weather Company, accessible via the provided URL, as the official and final source for determining precipitation levels. This consistent methodology ensures uniform evaluation across all locations, allowing participants to assess the probability of rain based on authoritative weather reporting.
