Lowest temperature in Boston on Jun 12, 2026?

Prediction market odds reflect real-money bets from traders and often diverge from traditional weather forecasts issued by meteorologists and government agencies. While meteorologists rely on atmospheric models and historical data, this market aggregates the collective judgment of participants who have financial incentive to forecast accurately. In the months leading up to June 12, 2026, comparing the implied probability from market odds to published seasonal outlooks and expert predictions can reveal where traders see opportunities or risks that conventional forecasts may underweight. Such comparisons help identify whether the market is pricing in tail risks or consensus expectations.

Traders compete to set the odds by posting limit orders, and the market price reflects the last executed trade or the midpoint of the current bid-ask spread.

As new information emerges or trader conviction shifts, prices adjust in real time, allowing participants to enter or exit positions at market rates.

This market resolves around Jun 13, 2026, once June 12, 2026 has passed and the lowest temperature for that day in Boston is verifiable from credible public sources. The outcome is determined by the actual recorded minimum temperature on that date, measured at an official weather station or recognized meteorological authority. Traders who correctly predicted the temperature range will receive their payout, while incorrect predictions expire worthless. Resolution is final once the data is confirmed and published.

Several factors could shift odds in this market over the coming months. Updated seasonal climate forecasts, particularly those issued by NOAA or international meteorological bodies, often trigger repricing as traders incorporate new model runs. Major weather patterns—such as developing La Niña or El Niño conditions—can influence June temperatures across the Northeast. Historical analogues to similar years may also sway sentiment. As June 12 approaches, short-term weather models become more reliable, typically causing sharper price movements in the final weeks. Real-time atmospheric data and any unusual climate events will keep traders actively reassessing their positions.
