Market context

Shenzhen's weather on 31 May 2026 will be measured against historical temperature records from Bao'an International Airport, the city's primary meteorological observation point. Late May sits within Shenzhen's pre-monsoon period, when subtropical high-pressure systems typically drive afternoon temperatures into the high 20s to low 30s Celsius. The settlement window closes at midday UTC, meaning only temperatures recorded up to that point will count toward resolution.

Shenzhen's May temperatures have shown consistent patterns across decades of records. Between 2015 and 2024, the highest May temperatures at Bao'an ranged from 32 to 35 degrees Celsius, with most years clustering around 33–34 degrees. Extreme heat events pushing above 35 degrees occur but remain uncommon for this month; such readings typically arrive later in June when the South China Sea monsoon circulation strengthens. The 0% crowd probability suggests traders expect a relatively cool day by local standards, though this may reflect uncertainty about accessing historical baseline data rather than genuine confidence in below-average conditions.

Tropical cyclone activity represents the primary weather catalyst affecting May 31 conditions. The Western Pacific typhoon season officially begins 1 June, but systems occasionally develop in late May and alter wind patterns across southern China. Real-time monitoring of the China Meteorological Administration's forecasts and any tropical depression alerts issued in the week prior will signal whether anomalous cloud cover or precipitation might suppress afternoon heating. Wunderground's historical records remain the binding settlement source, requiring traders to verify data availability and station continuity ahead of the resolution date.
