National Weather Service forecasts for Austin on August 18, 2026, center on a high near 102°F amid persistent high pressure, clear skies, and south-southeast flow that limits cloud cover and maximizes solar heating. This aligns with late-summer climatology where average highs reach about 99°F, yet recent consecutive days above 100°F under a dry regime have reinforced trader expectations for the 102–103°F bin at 56% implied probability and the 100–101°F range at 36.5%. Model consensus shows low precipitation chances and no significant cooler air advection, though minor shifts in timing or local variations could still influence the exact maximum before official readings. Historical records above 110°F remain rare in this pattern.

This market will resolve based on the highest temperature recorded in the 'Daily Observations' table on Weather Underground, not the figure displayed in the 'Day High & Low' summary section; in the event of any discrepancy between the two, the Daily Observations table shall be the primary resolution source not the Day High & Low section.
This market will resolve to the temperature range that contains the highest temperature recorded at the Austin-Bergstrom International Airport Station in degrees Fahrenheit on 18 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day for the Austin-Bergstrom International Airport Station, available here: https://www.wunderground.com/history/daily/us/tx/austin/KAUS.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
The resolution source for this market measures temperatures to whole degrees Fahrenheit (eg, 21°F). Thus, this is the level of precision that will be used when resolving the market.
