Highest temperature in Sao Paulo on June 13?

What you need to know

This market is asking: on June 13, 2026, what will the single highest temperature of the day be at São Paulo's Guarulhos Airport? The three options are 21°C, 22°C, or 23°C — think of a mild late-autumn day in São Paulo, since June is winter in the Southern Hemisphere. Whichever single peak temperature the airport weather station records that day is the answer. No ranges or averages — just the one highest reading of the whole day. The market settles based on the peak temperature logged by the Guarulhos Airport weather station on June 13, 2026, as reported by Weather Underground. The reading is rounded to the nearest whole degree Celsius. The result is confirmed only after the first data point from June 14 appears on that site — meaning late-day corrections on June 13 can still count, but any changes made after June 14 begins are ignored. Whoever's option matches that final peak reading wins. No recent news relevant to São Paulo weather or this market was provided. The one headline available is about Indian politics and has no connection here. What would actually matter to watch: any seasonal weather forecasts for São Paulo in mid-June, or reports of an unusual cold or warm front approaching the region in the days before June 13. June in São Paulo is reliably mild, which is why the market clusters tightly between 21°C and 22°C — but a single day's peak temperature is genuinely hard to nail. A passing cold front could push the high down to 20°C or below; a sunny, calm day could push it to 23°C or beyond. The gap between 21°C and 22°C is just one degree, meaning a small shift in cloud cover or wind can flip the outcome entirely. The market is also still about a year away, so long-range precision is limited.
