Highest temperature in Sao Paulo on June 30?

Platform comparison

Market context

Sao Paulo in June typically experiences mildly cool, breezy conditions with average highs of 23°C and lows of 13°C, making extreme heat unlikely during this month [1]. Historical records show the city’s hottest day reached 38.5°C in November 2023, while its coldest dipped to 3.1°C in July 2021, confirming that June sits firmly in the cooler half of the annual temperature range [6]. The current crowd-implied probability of 0% YES aligns with this pattern, as June has never produced record-breaking highs in recent decades, and the average daytime clarity of 12.5 hours suggests stable, non-extreme weather [1].

Traders should monitor Wunderground’s daily updates for the Guarulhos International Airport Station, as any sudden deviation from the 23°C average could signal an anomaly worth investigating [8]. While no immediate weather alerts have been issued for late June 2026, PredictWind’s historical June 2026 data indicates consistent temperature trends with no spikes above 25°C so far [7]. A trader must watch for official announcements from Brazil’s National Meteorological Institute regarding unexpected heatwaves, though such events are statistically rare in June and would require a significant shift in regional climate patterns to materialise.
