Pronóstico: Highest temperature in Beijing on July 5?

Platform comparison

Market context

On 5 July 2026, the Beijing Capital International Airport Station will record its peak temperature for the day, a single data point that determines whether the market resolves to the 30°C–35°C range. Current crowd-implied probability sits at 0% YES, suggesting traders believe the day will fall below 30°C, yet historical climatology paints a different picture. July in Beijing is reliably hot, with daily highs averaging around 31°C (88°F) and rarely dipping below 26°C (78°F) [1]. In fact, on 5 July 2010, the same station recorded a scorching 42.1°C, the hottest day in the local dataset for that date [6]. Even in 2023, the month peaked at 40°C, underscoring that sub-30°C days in early July are exceptional outliers rather than the norm [4]. The 0% probability appears to ignore these robust precedents, creating a stark disconnect between market sentiment and established weather records.

Traders must monitor immediate atmospheric developments, particularly the persistence of the current heatwave that has already pushed June temperatures to record highs for the month [7]. While no specific forecast for 5 July 2026 is yet available, the trend of increasingly intense summer heat in China is undeniable, with July 2024 marking the hottest month in recent national history [5]. A sudden shift in wind patterns or an unexpected rain event could be the catalyst that lowers temperatures, but the baseline expectation remains high. The settlement window closes at 12:00 UTC, so any late-morning weather bulletins from Wunderground will be critical [9]. Given the historical tendency for extreme heat on this date, the current 0% pricing seems vulnerable to a rapid correction if the day follows the typical July pattern of sustained high temperatures.

What are live sports odds on Polymarket?

Some top-tier matches stay open during play — you can trade the half-time probability in the 70th minute. Polymarket mid-prices update second-by-second; any frontend mirroring the order book shows the same movement.

How fast do sports winnings settle?

What's the difference between match odds and outright odds?

Match odds cover a single game ("Bayern beats BVB"). Outright odds are long-term aggregates ("Bayern wins the league"). Outright markets have deeper liquidity; match markets have faster resolution.

Can I import form data and lineups?

This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
