Highest temperature in Sao Paulo on July 9?

Platform comparison

Market context

The real-world event driving this market is the highest temperature recorded at São Paulo-Guarulhos International Airport on 9 July 2026, measured in degrees Celsius. Historical data confirms July is São Paulo’s coolest month, with average highs between 11°C and 22°C, rarely exceeding 23°C [8]. Current crowd-implied probability for a YES outcome sits at 0%, aligning with the 98% market consensus that the temperature will be 22°C, while 23°C holds only a 1% chance [1]. This probability framing reflects typical winter conditions rather than extreme heat events, such as the recent Rio heat wave where perceived temperatures reached 62°C, which is not representative of São Paulo’s July climate [5].

Traders should monitor official weather bulletins from AccuWeather and Wunderground for any anomalies, as sudden shifts could alter the resolution [3]. Although no immediate catalysts are announced, dependencies include the reliability of the Wunderground data feed and the timing of the settlement window ending 2026-07-09T12:00:00Z. Regulatory considerations also matter: German GlüStV implications and US CFTC reach may affect market accessibility, particularly for platforms offering “no-KYC up to $1,500”, which allows broader participation without stringent identity checks for this specific market [1]. These factors shape the market’s liquidity and trader eligibility, ensuring compliance while maintaining open access.
