Description

This event tracks the lowest temperature reached in San Francisco on a specific date in the future, using data from a designated weather authority. It helps participants assess climate conditions and temperature trends for planning or speculative purposes. The outcome depends solely on the official temperature recording for that day.

Kalshi

The event resolves based on the minimum temperature recorded at San Francisco’s CLISFO station on August 20, 2026, as reported by The Weather Company. Six distinct temperature ranges are defined, each corresponding to a separate market outcome. If the minimum temperature falls within a specific range—51°F or below, 52–53°F, 54–55°F, 56–57°F, 58–59°F, or 60°F and above—the respective market is resolved as 'Yes.' All markets are mutually exclusive, meaning only one can resolve to 'Yes' depending on where the actual temperature falls. While other weather sources may offer similar data for reference, The Weather Company’s report is the sole authority for determining the final outcome. This structure ensures clarity and objectivity in resolving the event based on a single, verified data point.
