Highest temperature in Shenzhen on July 14?

Platform comparison

Market context

On 14 July 2026, the highest temperature recorded at Shenzhen Bao'an International Airport will determine the settlement range for this market. Shenzhen's subtropical climate produces consistently hot and humid conditions during mid-July, with historical highs typically ranging between 32–35°C. The 0% crowd-implied probability suggests traders are either uncertain about the exact range boundaries or expect the market to resolve outside all listed options—an unusual positioning for a straightforward meteorological event with reliable historical data.

Shenzhen's July temperatures have remained stable across decades of records. Between 2010 and 2024, the airport station recorded July highs averaging 33–34°C, with extremes rarely exceeding 36°C or falling below 31°C. This consistency provides a strong baseline for assessing where the actual reading will land. The absence of any meaningful probability allocation across available ranges suggests either incomplete market participation or disagreement over how the resolution brackets are structured.

Traders should monitor the China Meteorological Administration's ten-day forecasts as mid-July approaches, though such predictions typically stabilise only 5–7 days before the settlement date. Tropical cyclone activity in the South China Sea could introduce volatility; the Northwest Pacific typhoon season peaks in August but occasionally affects Shenzhen in early-to-mid July. Current seasonal patterns favour temperatures within the historical norm, but the complete absence of market pricing indicates participants may be waiting for clearer forecast data before committing capital.
