This event tracks the lowest temperature recorded in San Francisco on a specific date in the future, using data from a designated weather provider. The outcome depends entirely on the official temperature reading for that day, with different markets covering various temperature ranges.
All markets resolve based on the minimum temperature recorded at San Francisco (CLISFO) on September 19, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 52°F or below, 53°F to 54°F, 55°F to 56°F, 57°F to 58°F, 59°F to 60°F, or above 60°F. The Exchange uses The Weather Company's official reporting as the sole determinant, even if other sources show different values. Preliminary data may be subject to rounding or conversion differences, and the Exchange reserves the right to delay resolution if it identifies a material error in the initial publication. If no valid data exists by the expiration date, markets resolve to the last fair price determined by the Exchange. The "Final" status on The Weather Company's platform is informational only and does not guarantee data accuracy or exempt markets from potential revisions.
