Weather markets make uncertainty tangible

Weather is one of the clearest ways to show how prediction markets work. People understand rain, snow, wind, temperature, and records. The data is usually public, and the deadline is clear.

A good Nordic weather market might ask whether Copenhagen records measurable snow by a date, whether Oslo reaches a named temperature threshold, or whether Stockholm has a wetter-than-normal month according to an official weather agency.

The rules matter

Weather markets need exact stations, time windows, units, and data sources. “Will it be a cold summer?” is too vague. “Will the mean temperature at a named station be below the 1991-2020 normal for June?” is much better.
