Highest temperature in Guangzhou on July 1?

Platform comparison

Market context

The real-world event this market tracks is the peak air temperature recorded at Guangzhou Baiyun International Airport on 1 July 2026, measured in degrees Celsius. Historical data frames the current 0% probability for lower ranges as statistically sound; July in Guangzhou typically sees daily highs near 33°C (91°F), rarely dipping below 29°C (85°F)[2][7]. Extreme records further support this, with the highest temperature ever recorded in the city reaching 39.1°C on 1 July 2004, suggesting that outcomes below 35°C are highly improbable for this specific date[4]. Recent climate trends reinforce this, as China experienced its hottest July on record in 2024, with average temperatures eclipsing previous decades[3][6].

Traders should monitor official heatwave announcements from the Guangdong Meteorological Bureau and daily weather forecasts released by Wunderground, the designated resolution source[5]. The settlement window closes at 12:00 UTC on 1 July 2026, meaning any temperature spike before noon will determine the outcome. Regulatory accessibility remains a key factor for participation: under German GlüStV rules, platforms offering non-KYC access up to €1,500 (approx. $1,600) face strict licensing, while US CFTC reach extends to any market influencing US commerce regardless of location. This specific market’s "no-KYC up to $1,500" structure allows broader entry for retail traders but may limit institutional participation due to compliance dependencies. Recent reporting by Reuters confirms that temperature anomalies in southern China are increasingly linked to global warming patterns, making high-temperature outcomes more likely than historical averages alone would suggest[6].
