Description

This event tracks the maximum temperature expected in San Francisco on a specific date in the future. It categorizes possible temperature outcomes into distinct ranges, each corresponding to a different resolution condition. The official data source determines which range the actual temperature falls into.

Kalshi

The event resolves based on the maximum temperature recorded in San Francisco (CLISFO) on August 18, 2026, as reported by The Weather Company. Six temperature ranges are defined: 67°F or below, 68–69°F, 70–71°F, 72–73°F, 74–75°F, and greater than 75°F. If the recorded maximum temperature falls within any of these ranges, the corresponding market resolves to Yes. All markets except the one matching the actual temperature range resolve to No. While other weather sources may provide similar data for reference, The Weather Company’s report is the sole authority for determining the final outcome.
