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 Station will determine which temperature band this market resolves to. The resolution hinges on data from Weather Underground's Daily Observations table, which may differ from the Day High & Low summary section; the former takes precedence. Shenzhen's August climate typically produces daily highs between 32–35°C, though extreme heat events occasionally push readings above 36°C. The 0% crowd probability suggests traders currently expect no outcome matching the highest specified temperature range, though this reflects positioning rather than meteorological certainty.

Historical August temperatures at Bao'an Airport show consistent patterns: the past decade's August averages cluster around 32–33°C for daily highs, with extremes reaching 35–36°C during heat waves. The 2022 and 2023 August seasons recorded several days exceeding 34°C, providing a baseline for assessing tail-risk scenarios. Current crowd sentiment may underweight the frequency of above-normal heat in southern China's summer months, particularly given El Niño or La Niña phase influences on regional atmospheric conditions.
