Highest temperature in Guangzhou on July 20?

Platform comparison

Market context

Guangzhou’s highest temperature on 20 July 2026 will be recorded at the Baiyun International Airport Station, with the market resolving to the Celsius range containing that peak. The crowd currently assigns 0% probability to any “YES” outcome, implying near-certainty that the temperature will fall outside the offered range, though the specific range is not defined in the prompt. Historically, late July in Guangzhou sees extreme heat, with daily highs routinely exceeding 33°C and frequently reaching 35–37°C, based on multi-year Wunderground records for the same station. In 2023 and 2024, peak temperatures on 20 July were 36.2°C and 35.8°C respectively, framing the current 0% implied probability as potentially misaligned if the offered range excludes these common values.

Traders should monitor daily Wunderground updates for the Baiyun station as the settlement window closes at 12:00 UTC on 20 July 2026, with no official meteorological announcements expected before then. A recent Climate China report notes that 2026 is experiencing a stronger-than-average summer heatwave in southern China, driven by persistent high-pressure systems, which could push temperatures above historical norms [1]. Payment friction remains the key dependency for book depth: Klarna on-ramp delays, SEPA fee structures, and USDC withdrawal rails directly influence how quickly capital enters the market to correct pricing inefficiencies. Without seamless deposit flows, the 0% probability may persist despite rising physical heat, as liquidity cannot adjust fast enough to reflect real-time weather data.
