Highest temperature in Beijing on July 14?

Platform comparison

Market context

Beijing's highest temperature on 14 July 2026 will be recorded at Capital International Airport Station and resolved against historical data from Wunderground. July is Beijing's warmest month, with average highs around 29–30°C, though extremes regularly exceed 35°C during heat waves. The settlement mechanism relies on a single official weather station rather than city-wide averages, which concentrates basis risk on localised conditions at the airport site.

Historical July records for Beijing show the city has experienced temperatures above 40°C on multiple occasions since 2010, with the all-time record of 41.9°C set in June 1961. The 0% crowd probability on this market likely reflects the absence of a defined upper temperature threshold in the market structure—traders cannot assess which specific range the market setter has established without viewing the full resolution brackets. This contrasts with Kalshi's typical approach of offering discrete temperature bands with transparent decimal odds, whereas some competitors like Smarkets display implied probabilities directly. The absence of visible odds scaffolding here creates friction for comparative shopping across platforms.

Traders monitoring this market should track China Meteorological Administration forecasts released in early July 2026, which typically provide 10-day outlooks. El Niño or La Niña conditions in the Pacific influence East Asian summer temperatures; current climate indices will shape whether July 2026 follows cooler or warmer-than-average patterns. The settlement window closes at 12:00 UTC on 14 July, requiring traders to account for Beijing's UTC+8 timezone when interpreting real-time temperature updates from Wunderground during the day.
