This event tracks whether San Antonio will experience consecutive days of high temperatures during a specific week. It focuses on determining if the average daily temperature exceeds a set threshold for multiple days in a row, reflecting potential heatwave conditions.
The event evaluates whether San Antonio experiences consecutive days with average temperatures strictly above 90°F during the week of August 31 to September 6, 2026, with varying thresholds for the number of consecutive days required. Each market specifies a different minimum number of consecutive days needed for resolution to Yes—ranging from two to six days. For any day to count toward a streak, the average temperature must be strictly greater than 90°F, calculated as the arithmetic mean of hourly temperatures reported by The Weather Company at KSAT from midnight to midnight local time, rounded to the nearest whole degree. Days with exactly 90°F or fewer than 18 reported hourly values do not qualify and break any ongoing streak. All data used for resolution will be the values published by The Weather Company at the market’s expiration time, with any subsequent revisions disregarded. Only days within the specified week can contribute to a valid streak.
This market resolves around Sep 8, 2026, with the outcome confirmed once official temperature data for the specified week are verified against credible public sources such as government weather agencies. The exact number of consecutive days with average temperatures above 90°F will determine which contract — for a specific streak length or ‘no streak’ — pays out.
Key signals include medium- to long-range weather outlooks from the National Weather Service, unexpected shifts in atmospheric patterns like El Niño or La Niña developments, and extreme early-season heat events that could hint at a sustained high-temperature period. Any major forecast updates indicating higher or lower odds will likely drive trader activity and shift this market’s odds before resolution.
