Highest temperature in Shenzhen on June 8?

Active sub-markets

Market context

On 8 June 2026, Shenzhen will record its daily maximum temperature, measured at Bao'an International Airport Station and reported via Wunderground's historical database. The market currently prices at 0% YES across all temperature bands, reflecting either extreme illiquidity or a technical settlement issue rather than genuine forecasting consensus. Traders holding USDC on Polygon can deploy conditional tokens to express views on whether the high will fall into specific ranges—typically 25–30°C, 30–35°C, 35–40°C, or above 40°C—though the absence of any probability mass suggests the market may not yet be actively traded.

Shenzhen's June climate is consistently warm and humid, with historical highs typically ranging from 32–35°C during early summer. Data from the past five years shows June 8 specifically has seen highs between 31–34°C, with only occasional excursions above 35°C during particularly intense heat waves. The 0% pricing across all bands is anomalous given this seasonal pattern and suggests either a liquidity trap or a display lag rather than a genuine forecast that no temperature will be recorded.

Traders should monitor China Meteorological Administration forecasts released in early June 2026, which typically provide 7–10 day outlooks for Guangdong Province. Any significant heat dome or tropical system affecting southern China in early June could shift expectations materially upwards. Settlement hinges entirely on Wunderground's historical archive for Shenzhen Bao'an, making data availability and station continuity the key operational risks.
