Highest temperature in Shenzhen on July 24?

Platform comparison

Market context

Shenzhen’s heat is still running close to its July norm, with forecast highs clustering around 32–33C and overnight lows near 27C, while showers remain in the mix through the day. The latest local forecasts point to a warm, humid afternoon rather than an extreme spike, which helps explain why the market is still priced at 0% YES: the settlement requires the *highest* temperature at Shenzhen Bao’an International Airport, not just a typical daytime high.[1][4][11][15]

Historically, July in Shenzhen is the city’s hottest month, but the distribution is fairly tight, with daily highs often around 32–33C and only rarely pushing above 34C. WeatherSpark’s July climatology puts typical highs near 89F and rare highs above 93F, while AccuWeather’s July forecast range sits between 86F and 93F; that framing suggests the relevant band is the low-30s Celsius rather than a runaway heat event.[1][15] Heavy rain is common in the month overall, and Shenzhen’s summer weather is influenced by the subtropical high and occasional typhoon activity, which can suppress or briefly enhance temperatures depending on cloud cover and rainfall timing.[11][13]

For traders, the key catalyst is the airport’s actual afternoon peak, because a short-lived break in cloud cover can still lift the day’s maximum even if the broader forecast looks wet. The main things to watch are hourly forecast revisions, any thunderstorm or heavy shower timing shifts, and whether the airport station records a hotter-than-expected reading before the settlement window closes; BBC Weather already shows humid, showery conditions and 28C at observation time, which supports a warm but not obviously exceptional peak so far.[2][4][14]
