This event tracks whether Phoenix will experience consecutive days with average temperatures exceeding 90°F during a specific week. The focus is on identifying temperature patterns over a defined period, reflecting potential impacts of heatwaves on local conditions.
The event evaluates multiple thresholds of consecutive days with average temperatures strictly above 90°F in Phoenix from August 18 to August 24, 2026. Each market corresponds to a different minimum streak length (2, 3, 4, 5, or 6+ days). For any market to resolve as Yes, the specified number of consecutive days must meet the temperature requirement solely within the official week. The daily average temperature is calculated as the mean of hourly readings reported by The Weather Company from midnight to midnight local time, rounded to the nearest whole degree. If a day records exactly 90°F, it does not count toward any streak. Additionally, any day with fewer than 18 hourly temperature reports invalidates that day for streak purposes and breaks any ongoing streak. All data used for resolution will be the official readings published at the market's expiration time, with no adjustments for later revisions.
This market resolves around Aug 25, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. Specifically, official meteorological data for Phoenix will be examined to determine whether six or more consecutive days of average temperature above 90°F occurred during the week of August 18, 2026.
Several signals could shift this market before Aug 25, 2026. Early summer heat waves, updates from long-range weather models, and monsoon development patterns may all influence trader sentiment. Additionally, any unexpected climate phenomena — such as an early El Niño effect — could cause rapid re-pricing of odds as the market approaches its resolution window.
