Highest temperature in Shenzhen on June 4?

Market context

On 4 June 2026, the highest temperature recorded at Shenzhen Bao'an International Airport will determine which range this market settles into. The 0% crowd probability currently priced on Polymarket suggests traders are either confident the settlement will fall outside all offered ranges, or the market lacks sufficient liquidity and participation to reflect genuine uncertainty. USDC conditional tokens on Polygon are trading at effectively zero value across all temperature buckets, indicating minimal conviction in any particular outcome.

Shenzhen's June climate is remarkably consistent. Historical data from Bao'an Airport shows June highs typically cluster between 28–32°C, with extreme readings rarely exceeding 34°C or falling below 26°C. The city's subtropical monsoon pattern means early June sits in the pre-peak summer period, before the most intense heat arrives in July and August. Comparable years show June 4th specifically has recorded highs of 29–31°C in recent decades, providing a narrow historical band against which to calibrate range expectations.

The primary catalyst affecting June 2026 temperatures will be the strength and timing of the South China Sea monsoon system. Weather forecasting models typically gain reliable predictive power only 10–14 days before the settlement date, meaning traders should monitor meteorological updates from the China Meteorological Administration and international models (ECMWF, GFS) as early June approaches. Any unusual atmospheric patterns—such as tropical cyclone activity or anomalous high-pressure systems—would shift outcomes materially, though such events remain inherently difficult to predict six months in advance.
