Description

This event tracks the highest temperature recorded in Washington DC on a specific date in 2026. The outcome depends on official weather service data, ensuring consistency and reliability for participants. It reflects real-world climate monitoring and forecasting challenges.

Kalshi

All markets resolve based on the maximum temperature recorded at Washington DC on July 28, 2026, as reported by the National Weather Service's Climatological Report (Daily) for Washington-National. Each market corresponds to a specific temperature range: 81° or below, 82-83°, 84-85°, 86-87°, 88-89°, or 90° and above. The official data source must be accessed via the provided NWS URL, using the latest available Daily Climate Report for the date. Participants should note that preliminary data may contain rounding or conversion nuances, and only the final NWS report determines resolution. All markets are mutually exclusive and collectively exhaustive, with exactly one resolving to Yes based on where the actual temperature falls within these defined ranges.
