Consecutive days of average temperature in Houston above 90°F - week of Aug 24, 2026

Kalshi

Multiple markets within this event evaluate consecutive days of average temperatures above 90°F at KIAH in Houston during the week of August 24–30, 2026, with varying required streak lengths from two to six days. For any market to resolve as Yes, the specified number of consecutive days must each meet the condition of a strictly greater-than-90°F average temperature, calculated as the arithmetic mean of hourly temperatures from 12:00 AM to 11:59 PM local time, rounded to the nearest whole degree. An exact 90°F average does not qualify, and only days within the official date range count toward the streak. If a day records fewer than 18 hourly temperature values, it invalidates the streak, resetting the count for that market. 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. The resolving Yes condition escalates with each market, requiring progressively longer heat streaks.
