Highest temperature in Shenzhen on July 20?

Platform comparison

Market context

Shenzhen’s Bao’an International Airport is currently overcast with a temperature of 84°F (29°C), while the RealFeel® hits 95°F (35°C) amid 83% humidity and 91% cloud cover. The market asks whether the day’s peak will fall into a specific Celsius range, yet the crowd-implied probability for the YES outcome sits at 0%, suggesting traders expect the maximum to land outside the offered bracket. With settlement locked to 2026-07-20T12:00:00Z and data sourced from Wunderground’s Bao’an station history, the event hinges on a single day’s meteorological record in one of China’s hottest cities.

Historically, mid-July in Shenzhen routinely sees highs between 33°C and 36°C at Bao’an, with record peaks occasionally reaching 38°C during heatwaves. A 0% probability implies the market’s range is either implausibly low or misaligned with typical summer extremes, mirroring past mispricings where traders underestimated humidity-driven heat stress. Comparable cases from 2023–2025 show Bao’an’s July maxima consistently exceeding 32°C, making a zero-probability stance on a range below that threshold statistically fragile unless the bracket is unusually high.

Traders should monitor real-time Wunderground updates for Bao’an and Accuweather’s hourly forecasts, as cloud cover and wind shifts can suppress peaks. No formal announcements or schedules govern this event, but sudden changes in regional humidity or monsoon activity—often reported by China Meteorological Administration bulletins—could alter the outcome. Recent heatwave coverage in southern Guangdong from Accuweather confirms that even overcast conditions can yield high RealFeel temperatures, reinforcing the need to watch live station data rather than rely on historical averages alone[1].
