Description

This event tracks whether San Diego will experience specific temperature ranges on a particular day in the future. The outcome depends solely on the official temperature recording from a designated weather source, reflecting climate conditions and measurement accuracy.

Kalshi

All markets resolve based on the maximum temperature recorded at San Diego (CLISAN) on October 18, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: below 83°F, 83-84°F, 85-86°F, 87-88°F, 89-90°F, or above 90°F. The Weather Company’s data is the sole authority, though preliminary readings may differ from final values due to rounding or conversion. If a material error is identified in the initial publication before expiration, the market may be held pending correction. If no valid data exists at 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 override these resolution procedures.
