Highest temperature in Shanghai on June 30?

Platform comparison

Market context

The real-world event this market tracks is the peak daytime heat recorded at Shanghai Pudong International Airport on 30 June 2026, measured in degrees Celsius. Historical data for June at this station shows daily highs typically rising from 77°F to 83°F, rarely dipping below 69°F or exceeding 92°F [1]. Summer conditions in Shanghai regularly breach 30°C, with temperatures climbing to 35°C during the most intense sunny spells [6]. The current crowd-implied probability of 33% for a specific temperature range aligns with these patterns, suggesting traders are weighing the likelihood of an unusually warm day against the typical seasonal average.

Traders should monitor real-time weather updates and any sudden shifts in solar radiation or wind speed, as these directly influence peak temperatures. Recent forecasts for June 2026 indicate daily highs between 80° and 85°, with overnight lows stabilising around 75° to 76° [5]. While no specific weather announcements are pending, the settlement depends entirely on Wunderground’s recorded maximum for the day, making data availability a key dependency [1]. The market’s traction reflects broader funding flows; as deposit fees and withdrawal rails via Klarna, SEPA, and USDC become more efficient, book depth increases, allowing larger positions to shape the implied probability more accurately.
