About This Market

This market tracks the official daily minimum temperature recorded at Logan International Airport in Boston on April 21, 2026. It serves as a localized weather derivative, allowing participants to hedge against or speculate on specific climatic outcomes in a coastal New England environment.

April in Boston is characterized by significant meteorological volatility as the region transitions from winter to spring. Historical data shows that temperatures during this period are heavily influenced by the interplay between retreating cold Canadian air masses and the moderating effects of the Atlantic Ocean, often resulting in wide daily variance.

Market valuations reflect the collective assessment of meteorological forecasts and long-term climatological trends for that specific date. Higher prices indicate where the market anticipates the daily low is most likely to settle within the designated temperature bands.

Key Factors

Frequently Asked Questions

Which weather station is used to determine the official result?

The data is sourced from the official National Weather Service readings recorded at Logan International Airport (BOS).

How is the 'lowest temperature' defined for this market?

The lowest temperature is defined as the minimum dry-bulb temperature recorded during the 24-hour calendar day on April 21, 2026.

Does a shift in the jet stream significantly impact this specific date?

Yes, a northward or southward shift in the jet stream can drastically alter the thermal baseline for Boston, potentially pulling in unseasonable arctic air or warmer southern flows.

How do coastal effects impact the minimum temperature in Boston?

Because Boston is a coastal city, the temperature of the Atlantic Ocean acts as a thermal buffer, often preventing overnight lows from reaching the extremes seen in inland Massachusetts.

What happens if there is an equipment failure at the Logan Airport weather station?

In cases of official station data gaps, the market typically defaults to the National Weather Service's finalized climatological reports or designated secondary official sources.
