Austin, Texas experiences significant temperature variation throughout spring months. On April 20, 2026, meteorological data will determine whether the highest temperature recorded in Austin falls within the narrow 70-71°F range. This specific temperature band represents a relatively cool spring day for Austin, where April averages typically range from the mid-60s to low-80s Fahrenheit. The market currently prices the YES outcome at 4%, reflecting the narrow range required—just one degree difference. This low probability reflects how specific the prediction is: temperatures must peak at exactly 70°F or 71°F, with no variation above or below. Weather forecasting becomes increasingly uncertain as the required range tightens, making narrow temperature predictions inherently difficult to achieve. The 4% odds suggest traders view this outcome as unlikely given broader temperature patterns typical for late April in Austin. The market resolves based on official National Weather Service data recorded for Austin-Bergstrom International Airport. With 24-hour volume of $8,777, this represents modest interest in this particular weather prediction market.
