Description

This event tracks the lowest temperature recorded in Philadelphia on July 21, 2026. The outcome will be determined by the official National Weather Service Climatological Report for that date, with resolution based on which temperature range the recorded minimum falls into.

Kalshi

Resolution is determined by the minimum temperature recorded at Philadelphia on July 21, 2026, as reported in the National Weather Service's Climatological Report (Daily). The official data source is accessed through the NWS website by navigating to the "Observed Weather" tab and selecting "Philadelphia, PA" with Daily Climate Report. The recorded minimum temperature will fall into one of six ranges: 64°F or below, 65-66°F, 67-68°F, 69-70°F, 71-72°F, or 73°F or above. Each range corresponds to a distinct market outcome. Traders should note that preliminary NWS data may be subject to rounding and conversion nuances, and the final official NWS Climatological Report (Daily) is the authoritative source for resolution, superseding other weather data sources.
