Highest temperature in Beijing on July 4?

Platform comparison

Market context

On 4 July 2026, the Beijing Capital International Airport Station will record its peak temperature for the day, a real-world event that determines whether the market resolves to the 35°C range or higher. Historical data shows July in Beijing is consistently hot, with daily highs averaging around 31°C and rarely dropping below 26°C, while extreme peaks have reached 42.1°C in 2010 and 40°C in 2023[1][3]. The current crowd-implied probability of 0% for the 35°C range appears misaligned with these patterns, as recent years confirm temperatures frequently breach this threshold, with China’s July 2024 average hitting a record 23.2°C, 1.1°C above the 1961 benchmark[2][5].

Traders should monitor the daily weather bulletins from the China Meteorological Administration and Wunderground’s live updates, as forecast models for early July 2026 suggest a high-pressure system could drive temperatures above 35°C[3]. A recent Reuters report highlighted that China recorded its hottest month in recent history last year, reinforcing the likelihood of extreme heat in Beijing during July[2]. The market’s traction correlates directly with funding flows from payment rails like Klarna and SEPA; as deposit fees drop and withdrawal rails such as USDC become more efficient, book depth increases, allowing larger positions to be taken on these temperature outcomes. Thin volume currently obscures true sentiment, but the historical precedent of 41.9°C in 1999 and 42.1°C in 2010 suggests the 35°C range is a plausible resolution point[8][9].
