Highest temperature in Miami on May 31?

“Highest temperature in Miami on May 31?” is a weather prediction market asking traders to forecast the hottest temperature recorded at Miami Intl Airport Station on May 31, 2026. The market resolves to the temperature range containing the day’s high, using Wunderground’s historical daily data for KMIA and whole-degree Fahrenheit measurements. It will not resolve until the first data point for June 1 is published, allowing final revisions to the day’s readings before settlement.

This event matters because it reflects short-term weather expectations for Miami and how market sentiment is pricing the day’s heat risk. With current market probability around 95%, traders appear to expect a high temperature range close to the top of the listed outcomes, though that probability is not a guarantee. The market runs from May 29 through May 31, 2026, making it a time-sensitive forecast tied directly to local weather conditions. As with other weather prediction markets, odds can shift as new forecast data becomes available and as the expected outcome changes.
