This event tracks the lowest temperature reached 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 recording, with specific ranges determining different results.
All markets resolve based on the minimum temperature recorded at San Francisco (CLISFO) on September 20, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 52°F or below, 53-54°F, 55-56°F, 57-58°F, 59-60°F, or above 60°F. The Weather Company’s data is the sole authority, and preliminary readings may differ from final values due to rounding or conversion. If a material error is identified in the initial data before expiration, the resolution may be delayed until corrected data is published or until the expiration date. If no data remains available by expiration, markets resolve to the last fair price determined by the exchange. The "Final" status on The Weather Company’s platform is informational and does not guarantee error-free data.
