Market context

Beijing's weather in early June typically sits in the warm-to-hot range as the city transitions into summer. Historical records show that 4 June temperatures at the capital's main airport station have ranged from around 25°C in cooler years to peaks exceeding 32°C during warmer patterns. The 0% crowd probability suggests traders are either uncertain about the specific temperature bands available in this market or are waiting for clearer seasonal forecasts before committing capital.

June marks the onset of Beijing's pre-monsoon period, when high-pressure systems can drive temperatures upward, though occasional cloud cover and moisture from approaching frontal systems can moderate peaks. The settlement window closes at midday on 4 June 2026, meaning only temperatures recorded up to that point will count toward resolution. Current meteorological models for early June 2026 remain preliminary; traders should monitor updates from China's National Meteorological Centre and international weather services in the weeks leading to the settlement date, as these will provide increasingly precise forecasts for the specific temperature range that resolves the market.
