Description

The maximum temperature recorded in Boston on June 11, 2026, will be measured according to the National Weather Service's official climatological data. This event tracks the actual high temperature observed at that location on the specified date.

Kalshi

Resolution is based on the maximum temperature recorded at Boston on June 11, 2026, according to the National Weather Service's Climatological Report (Daily), accessible via the CLIBOS database at Boston (Logan Airport), MA. The official NWS data serves as the authoritative source, superseding preliminary reports or alternative weather services. Temperature data is rounded to the nearest degree Fahrenheit. If NWS data is unavailable for the specified date, the most recently published data will be used. Traders should note that preliminary NWS reporting may contain rounding and conversion nuances that differ from final published values.

Frequently asked questions

The PredictionHero dashboard tracks real-time odds and trading activity for the highest temperature forecast in Boston on June 11, 2026, on Kalshi. You can monitor the current implied probability of each temperature outcome, 24-hour volume of $49,199, and total group volume of $56,625. The dashboard updates continuously as traders buy and sell shares, reflecting the market's collective expectation for peak temperature that day. This live data helps you gauge consensus sentiment and identify shifting market confidence in specific temperature ranges as new weather data emerges.

Prediction market odds on Kalshi represent real-money consensus from active traders and differ from traditional meteorologist forecasts. While weather analysts rely on numerical models and historical patterns, prediction markets incorporate trader beliefs about model accuracy, potential forecast revisions, and late-breaking weather signals. Markets often price in tail-risk scenarios that analysts downweight. Comparing Kalshi odds to National Weather Service or private forecaster predictions for Boston's June 11 high can reveal whether traders expect warmer or cooler conditions than official guidance, and by how much.

On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. On Kalshi, the highest temperature in Boston on June 11, 2026 is priced as a set of outcome contracts, each representing a specific temperature range or exact value. Traders buy and sell shares in each outcome; the price of a share reflects the market's implied probability that outcome will occur. As new weather forecasts, seasonal patterns, or climate data surface, traders adjust positions, moving prices up or down. The outcome with the highest price typically represents the market's most-favored temperature range for that date.

The market resolves on Jun 12, 2026, after the highest temperature in Boston on June 11, 2026 has been recorded and verified. Resolution depends on the official temperature reading from a designated weather station or data source specified by Kalshi at market creation. Once the actual high temperature for that day is confirmed, the outcome contract matching that temperature (or range) is marked correct, and traders holding winning shares receive their payout based on the contract price they paid.

Major weather pattern shifts, updated seasonal forecasts, and atmospheric indices like the North Atlantic Oscillation or jet-stream positioning can move odds significantly. Tropical systems, heat domes, or cold fronts approaching the Northeast in early June would trigger repricing. Real-time model consensus changes from major forecast centers—especially 7 to 10 days before June 11—often spark sharp trading. Climate anomalies, solar activity reports, or unexpected ocean-temperature updates may also influence trader expectations. As June 11 approaches, short-range forecasts become more reliable, typically stabilizing prices around the most probable outcome.
