Recent forecasts from sources like the BBC and timeanddate.com point to a peak temperature near 35–36°C in Chengdu on August 25, driven by the region's subtropical monsoon climate, high humidity around 60%, and light easterly winds that limit cooling. Subtle differences in model runs—such as scattered cloud cover versus clearer skies or brief thundery showers—account for the tight clustering of trader-implied odds around 35–37°C, as these factors can shift afternoon maxima by 1–2°C. Historical late-August averages hover near 30–32°C, but recent heat episodes have pushed readings higher, underscoring the role of urban heat retention and variable precipitation in creating genuine forecast uncertainty ahead of official China Meteorological Administration data.
