Pronóstico: Highest temperature in Beijing on July 4?

Platform comparison

Market context

Beijing will experience its peak summer heat on 4 July 2026, with the Beijing Capital International Airport Station recording the day’s highest temperature in degrees Celsius. The current crowd-implied probability of 0% for a “YES” outcome suggests the market expects temperatures to fall within a specific range, yet historical data and recent trends indicate significant volatility.

Historically, July in Beijing is reliably hot, with daily highs averaging around 88°F (31°C), rarely dipping below 78°F (26°C) or exceeding 96°F (36°C)[3]. The city’s all-time record high of 41.9°C occurred on 24 July 1999, while 2023 saw temperatures reach 40°C in July[2][6]. Recent weather patterns show Beijing experiencing record highs, with the Nanjiao observatory recording above 40°C for three consecutive days in late June 2026[2]. This context frames the 0% probability as potentially misaligned with the region’s typical July intensity, where temperatures frequently surpass 33°C[1].

Traders should monitor upcoming weather model updates from Wunderground, which will provide the definitive resolution data for this market[1]. Key catalysts include announcements from the China Meteorological Administration regarding heatwaves, as authorities have already urged residents to limit outdoor exposure due to record temperatures[2]. Additionally, any shifts in humidity levels or sudden cooling trends—such as the expected drop to 34°C on Monday before rising again later next week—could significantly alter the final temperature outcome[2]. Recent reports from Reuters highlight China’s hottest month in recent history, reinforcing the likelihood of elevated temperatures in early July[5].
