Description

This event tracks the lowest temperature recorded in Boston on a specific future date, using official government data. Participants assess whether temperature conditions will fall within certain ranges based on verified meteorological reports.

Kalshi

All markets resolve based solely on the official minimum temperature recording for Boston (Logan Airport, MA) on July 28, 2026, as reported in the National Weather Service's Climatological Report (Daily). The outcome depends on which numerical temperature range the actual low falls into: below 56°F, between 56-57°F, 58-59°F, 60-61°F, 62-63°F, or above 63°F. Traders must reference the specific NWS data portal for Boston climate reports, using the most current daily report available after the date passes. While preliminary or third-party weather sources may offer estimates, only the official NWS report determines resolution, and users should be aware that measurement methods and reporting timelines can create minor discrepancies in early data versions.
