Highest temperature in Shanghai on July 2?

Platform comparison

Market context

Shanghai is entering its peak summer heatwave, with July 2nd historically one of the hottest days of the month. The current crowd-implied probability of 0% for the highest temperature falling in the lowest range is entirely consistent with reality: daytime highs in Shanghai during July routinely exceed 35°C (95°F), often reaching 38°C (100°F) or higher[3][4]. AccuWeather’s July 2026 forecast for Pudong Airport predicts daily highs between 78°F and 93°F (26°C–34°C), with an average high of 89°F (32°C)[1]. Historical data confirms that 7–15 days per July see highs over 35°C, making a low-temperature outcome virtually impossible[3].

Traders should monitor the end of the “plum rainy season,” which typically concludes in early July, reducing rainfall and allowing temperatures to climb steadily[4]. The key catalyst is the timing of peak heat, which usually occurs around 3 PM, as seen in July 2025 when temperatures hit 38°C[4]. While no immediate weather announcements are scheduled, the high humidity averaging 76% will intensify muggy conditions, pushing perceived temperatures higher[3]. Watch for any sudden shifts in wind direction or cloud cover, as Pudong Airport’s coastal location can lead to rapid microclimate changes[2]. Recent passenger traffic data shows 95,600 flights in the first five months of 2026, indicating stable operational conditions with no weather-related disruptions[7].

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Prediction Today, which mirrors the Polymarket order book directly.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
