Description

This event assesses the expected weather conditions in Philadelphia on a specific future date, focusing on the highest temperature reached. Participants can evaluate various temperature ranges to forecast likely climatic outcomes for that day.

Kalshi

The event determines whether the maximum temperature in Philadelphia on September 20, 2026, falls within specific ranges as reported by The Weather Company. Each market corresponds to a distinct temperature range, with one market resolving if the temperature is 74°F or below, another for 75-76°F, and so on, up to a final market for temperatures above 82°F. The official temperature value is exclusively sourced from The Weather Company, and users should be aware that preliminary data may differ from the final reported value due to rounding or conversion issues. If a material error is identified in the initial data publication, the exchange reserves the right to delay resolution until a corrected value is released or until the expiration date. Should no data be available by the expiration date, all markets will resolve based on the last fair price determined by the exchange. The 'Final' status indicated on The Weather Company’s platform is informational and does not guarantee data accuracy or exemption from potential revisions.
