Description

This event tracks the highest temperature reached in San Francisco on a specific date in the future. It uses a single authoritative source to determine the outcome, ensuring consistency despite variations in other weather reports. Participants can speculate on whether the temperature will fall within certain ranges or exceed a threshold.

Kalshi

The event determines whether the maximum temperature in San Francisco on September 1, 2026, as recorded by The Weather Company, falls within specific Fahrenheit ranges. Each market corresponds to a distinct temperature band: 64° or below, 65-66°, 67-68°, 69-70°, 71-72°, or above 72°. The Weather Company’s official reported value is the sole arbiter, with all secondary guidance from other services considered informational only. Participants should be aware that preliminary data may vary due to rounding or conversion differences, and only the final reported value will resolve the markets. The structure allows for precise speculation on temperature outcomes across a spectrum of possible values.
