Description

This event tracks the total rainfall in Napa over a six-month period, offering multiple thresholds to assess varying levels of precipitation. Each threshold represents a different level of rainfall, allowing participants to evaluate the likelihood of exceeding specific amounts. The outcomes are determined by summing daily precipitation data from a trusted weather source.

Kalshi

The event resolves based on whether the total precipitation at the KAPC station in Napa from November 1, 2026, through March 31, 2027, exceeds specified thresholds. The total precipitation is calculated as the sum of The Weather Company's daily precipitation values for each reporting day within the period. If The Weather Company publishes an official total for the exact period, that total is used instead of the summed daily values. Six separate markets correspond to thresholds of 10, 15, 20, 25, 30, and 35 inches. For each market, if the calculated or published total exceeds the respective threshold, the market resolves to Yes; otherwise, it resolves to No. All markets share the same data source and calculation methodology, ensuring consistency across thresholds.
