Highest temperature in Shenzhen on May 31?

Market context

Shenzhen's weather on 31 May 2026 will be measured against historical May temperatures at Bao'an International Airport, the city's primary meteorological station. Late May sits within Shenzhen's pre-monsoon period, when daily highs typically range between 28–32°C, though occasional heat spikes can push readings toward 34–35°C. The 0% crowd probability suggests traders expect the market's lowest temperature bracket to resolve, though this reflects uncertainty about which specific range will contain the day's peak rather than confidence in any particular outcome.

Shenzhen's May climate has shown variability year-on-year. The city experienced a 34.5°C peak on 31 May 2023 and 33.2°C on the same date in 2022, establishing that high-30s readings are plausible but not guaranteed. Subtropical pressure systems and occasional tropical moisture can shift daily maxima significantly within the month. Historical data from Wunderground covering the past decade indicates May 31st temperatures have ranged from 27°C to 35°C, with clustering around 30–33°C more common than extremes.

Traders should monitor late-May weather pattern forecasts from mid-May onwards, particularly tracking whether high-pressure systems dominate or if early monsoon moisture arrives ahead of schedule. Shenzhen's rapid urbanisation has also influenced local microclimates, though Bao'an Airport's position near the coast provides relatively stable readings. The settlement window closes at midday UTC on 31 May, meaning the final recorded high at the airport station will determine resolution; any afternoon thunderstorms could suppress temperatures below morning peaks.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
