Highest temperature in Beijing on August 11?

Platform comparison

Market context

Beijing's highest temperature on 11 August 2026 will be measured at the Capital International Airport Station and recorded in Weather Underground's Daily Observations table. The settlement window closes at 12:00 UTC on that date, meaning the final reading must be captured before noon London time. The current crowd probability of 0% reflects either extreme confidence in a specific temperature band or insufficient trading activity to establish meaningful odds across the available ranges.

Historical August temperatures in Beijing show a consistent pattern: daily highs typically range between 28–35°C, with occasional peaks above 36°C during heat waves. The 0% probability assigned to this market's current framing suggests traders are either heavily concentrated in a single outcome band or the market lacks sufficient liquidity to distribute probability mass across multiple scenarios. Comparable weather markets on prediction platforms have shown that crowd estimates for specific-day temperature ranges in major cities tend to sharpen as the settlement date approaches, particularly when regional weather systems become visible in extended forecasts.

Traders should monitor China Meteorological Administration alerts and any heat wave warnings issued in late July or early August 2026, as these typically precede measurable temperature spikes. The China Weather Network and official Beijing municipal weather bulletins provide the most reliable early signals. Weather Underground's data feed from Beijing Capital International Airport has historically remained consistent with official Chinese meteorological records, though discrepancies between the Daily Observations and Day High & Low sections have occasionally required resolution clarification. Under German GlüStV and US CFTC frameworks, this market's accessibility remains subject to jurisdictional restrictions; however, the sub-$1,500 threshold for KYC-exempt participation in some regulatory zones may apply depending on individual trader classification and cumulative market exposure.
