Pronóstico: Highest temperature in Shenzhen on August 11?

Platform comparison

Market context

On 11 August 2026, the highest temperature recorded at Shenzhen Bao'an International Airport Station will fall into one of several defined ranges measured in degrees Celsius. The market currently prices all outcomes at 0% on Polygon, suggesting either extreme uncertainty about which temperature band will occur or minimal trading activity establishing a baseline. Traders settling positions in USDC will need to verify the exact reading from Weather Underground's Daily Observations table rather than the Day High & Low summary, a distinction that matters when temperatures cluster near range boundaries.

Shenzhen's August climate is remarkably consistent. Historical data from the past decade shows daily highs in mid-August typically ranging between 32–35°C, with occasional peaks above 36°C during heat waves. The city experiences its hottest period from late July through September, driven by the East Asian summer monsoon and urban heat island effects. August 2023 saw temperatures reach 35.4°C on the 11th; August 2024 recorded 34.1°C on the same date. This historical clustering suggests the market should reflect probabilities concentrated in the 32–36°C bands rather than extreme outliers.

Traders should monitor China Meteorological Administration forecasts released in early August, which typically provide 10-day outlooks with reasonable accuracy for temperature ranges. Tropical cyclone activity in the South China Sea occasionally disrupts normal August patterns, bringing cloud cover and lower peaks; the Western Pacific typhoon season runs June through November. Any significant weather system approaching southern China in early August would shift probability away from the typical 34–35°C range. Current conditions and seasonal patterns suggest the outcome will likely resolve within historical norms unless an unusual weather event intervenes.
