Description

This event tracks the highest temperature reached in Phoenix on a specific date in the future, using official government data. Participants assess climate conditions and historical trends to predict temperature ranges, with outcomes determined by verified meteorological reports.

Kalshi

All markets resolve based solely on the maximum temperature recorded in Phoenix, AZ on August 3, 2026, as reported by the National Weather Service's Climatological Report (Daily). The official data must be accessed via the provided NWS URL, navigating to the "Observed Weather" tab and selecting "Phoenix, AZ" with the Daily Climate Report for the exact date. Traders should use the latest available report, recognizing that update frequencies may vary by location. While third-party weather services may offer preliminary guidance, they are not authoritative—only the NWS report determines resolution. Preliminary NWS data may contain rounding or conversion nuances, so caution is advised when interpreting early readings. Each market corresponds to a specific temperature range or threshold: below 111°F, 111-112°F, 113-114°F, 115-116°F, 117-118°F, or above 118°F. The market that matches the actual reported temperature range will resolve as Yes, with all others resolving as No.
