Highest temperature in Sao Paulo on June 30?

Platform comparison

Market context

The underlying event is the peak heat recorded at São Paulo-Guarulhos International Airport on 30 June 2026, measured in degrees Celsius. Historical data shows June temperatures in São Paulo typically range between 55°F and 83°F, rarely exceeding 89°F [2]. Recent records indicate a high of 78.8°F (26.0°C) on 22 June 2026, while the all-time city record stands at 39°C (102.2°F) from November 2023 [1][4]. A notable winter heatwave in Brazil recently pushed temperatures near 104°F (40°C) in São Paulo, suggesting extreme variability is possible even in cooler months [7]. The current 0% crowd-implied probability for higher ranges likely reflects the typical June baseline, though the recent anomaly warrants caution.

Traders should monitor official weather bulletins from Brazil’s National Meteorology Institute (INMET) and real-time updates from Wunderground, the designated resolution source [3]. Key catalysts include scheduled heatwave forecasts for late June, which have previously driven temperatures above 40°C in the region [8]. A recent report from Brazil Reports confirms that record winter temperatures are increasingly common, with São Paulo hitting near 104°F during a recent event [7]. Payment flows on platforms like Polymarket-Klarna, including deposits via Klarna, SEPA, and USDC withdrawals, directly influence book depth; as funding increases, market sensitivity to these temperature catalysts intensifies. Watch for INMET announcements on 29–30 June, as dependencies on atmospheric pressure shifts could trigger rapid price movements.
