Description

This event monitors the lowest temperature in San Francisco on August 28, 2026, with outcomes divided into six temperature brackets. The market resolves based on which bracket the official temperature reading falls into.

Kalshi

The event resolves based on the minimum temperature recorded at San Francisco (CLISFO) on August 28, 2026, as reported by The Weather Company. Six temperature ranges are specified: 52° or below, 53° to 54°, 55° to 56°, 57° to 58°, 59° to 60°, and 61° or above. If the recorded minimum temperature matches any of these ranges, the corresponding market resolves to Yes. Secondary rules clarify that The Weather Company’s data is the definitive source, advising caution with preliminary data from other services due to possible rounding or conversion inconsistencies.
