This market asks whether measurable snow will occur in Boston during March 2026; it gives traders a way to express views or hedge exposure to winter weather risk. Outcomes matter for transportation, utilities, and seasonal planning in the Boston region.
Boston sits in a transition zone where March can produce late-season snowstorms or rapid warming toward spring, so historical March snowfall is variable from year to year. Large-scale climate drivers and the track of coastal storms (Nor'easters) strongly influence whether March produces measurable snow. The market aggregates forecasts and real-time information into a tradable signal about that outcome.
Market prices reflect the consensus of participants about the likelihood of snow in March 2026 and will update as new model runs, observations, and official forecasts arrive. Treat prices as a summary of collective expectations, not as a guarantee of a specific outcome.
The market's contract terms define the official measurement and threshold (for example, measurable accumulation). Consult the event page or contract rules on the exchange to see the exact definition and reference station used.
Many weather contracts use the calendar month in local time (from 00:00 on March 1 to 23:59 on March 31), but the precise start/end times are specified in the contract rules—verify those on the event page.
Whether mixed precipitation counts depends on the contract definition (snowfall occurrence vs. measurable snow accumulation and how observations are classified). Check the exchange's outcome rules or the specified observation procedure for clarification.
Exchanges commonly use an official National Weather Service station such as Logan, but the event page will list the exact observation site used for settlement—confirm there to avoid ambiguity.
Updated model guidance on storm tracks and temperatures, the arrival or absence of Arctic air masses, new ocean/atmospheric indices updates, and any watches/warnings issued by the NWS can all shift trader expectations and thus market prices.
