About This Market

This market tracks the official daily minimum temperature recorded at Logan International Airport in Boston on April 20, 2026. It serves as a localized hedge or speculative instrument for climate-conscious participants interested in New England spring weather patterns.

Boston’s spring weather is notoriously volatile due to the collision of maritime air from the Atlantic and continental air masses from the interior. Historically, mid-April in Boston features significant variance, with minimum temperatures ranging from near-freezing frost conditions to mild spring nights. Data is sourced from official National Weather Service reports for the Boston Logan site.

Market prices reflect the collective anticipation of how the specific weather conditions on that date will align with the provided temperature ranges.
