Highest temperature in Sao Paulo on June 15?

What you need to know

This market is asking: on June 15, 2026, what will the single highest temperature of the day be at São Paulo's Guarulhos International Airport? The answer is broken into ranges — right now the leading option is 19°C (about 66°F), which is a cool, mild winter day. A Yes on 19°C means the mercury peaks somewhere in that range and never climbs higher; a Yes on 20°C means it gets a little warmer, and so on. After June 15, 2026 ends, the market checks the Weather Underground website for the official high temperature recorded at Guarulhos Airport that day, measured in whole degrees Celsius — no decimals. Whatever single number that source shows as the daily high determines which range wins. One small detail: the market waits until the first data point from June 16 appears before settling, to allow any last-minute corrections to June 15's readings to come through. No relevant news was provided for this market. That's completely normal here — daily weather markets don't usually generate headlines in advance. What would matter to watch closer to the date is any forecast for São Paulo in mid-June, which falls in the city's dry winter season, typically bringing cool, stable temperatures. June is São Paulo's winter, so very high temperatures are unlikely — but the exact peak on any single day is genuinely hard to nail down. The market currently puts 19°C as the most probable outcome at 53%, with 20°C at 20%, meaning a meaningful share of uncertainty remains across nearby values. Day-to-day variation, passing cold fronts, or an unusually clear sunny afternoon can all shift the peak by a degree or two, and a single degree is enough to change the outcome entirely.
