Highest temperature in Shenzhen on August 14?

Platform comparison

Market context

On 14 August 2026, the highest temperature recorded at Shenzhen Bao'an International Airport will determine the settlement range for this market. The crowd currently assigns zero probability to the YES outcome, suggesting consensus expectation that the temperature will fall outside a particular threshold range—though the market description does not specify which range constitutes YES versus NO. This creates immediate ambiguity: without knowing the temperature band in question, traders cannot properly calibrate whether the 0% reading reflects genuine certainty or merely reflects confusion about the market's actual parameters.

Shenzhen's August climate is remarkably consistent. Historical data from the airport station shows daily highs cluster between 31–34°C during mid-August, with extreme readings rarely exceeding 35°C or falling below 30°C. The city's subtropical monsoon pattern produces little volatility in peak daily temperatures during this period. A 0% probability implies the market expects an outcome so far outside the historical norm that it warrants dismissal—either an unusually cool day or an unprecedented heat spike. Neither scenario is implausible given climate variability, but both would require significant atmospheric disruption.

The resolution mechanism specifies Weather Underground's Daily Observations table rather than the Day High & Low summary, a distinction that matters when automated station data occasionally diverges from manual corrections. Traders should verify which specific temperature band the market defines as YES before settlement approaches. Given the tight historical range and the absence of any announced weather system or heat event forecast for August 2026, the 0% probability may reflect either genuine consensus or simply lack of clarity about the settlement criteria.
