Highest temperature in Sao Paulo on July 23?

Platform comparison

Market context

The highest temperature at Sao Paulo-Guarulhos International Airport on 23 July is the relevant event, and the current **0% YES** implies the market is effectively pricing in a very low chance of an unusually hot reading. That is consistent with mid-winter conditions in São Paulo, where July averages are typically around **23°C** for daytime highs and **12°C** at night, with rain on only a minority of days[2]. Even so, the airport station can print a different maximum from city-centre averages, so late-morning sunshine, a delayed cloud deck, or a brief warm northerly flow can still matter more than the broader seasonal norm[2].

For context, weather markets like this often stay thin until the day of settlement because the outcome is a single recorded maximum, not a daily mean, and the book only needs one warm spike to move. That makes **funding friction** unusually relevant: traders who can move money in quickly through **SEPA**, **Klarna**, or **USDC** are better placed to react when the forecast shifts, while slow deposits or costly withdrawals tend to suppress depth until the final hours. In practice, market pricing often follows the same pattern as local forecast revisions: if precipitation odds rise or cloud cover increases, upside temperature scenarios get compressed, while a drier outlook can reopen the tail for a higher maximum[1].

The main catalysts are the airport-specific forecast updates and any intraday change in cloud, rain, or wind timing rather than broad national weather headlines. Temperatures.com currently flags **meaningful precipitation chances** around Thursday 23 July in São Paulo, which would usually cap the day’s maximum if showers arrive early and persist[1]. Traders should watch how those short-range updates evolve against the settlement source itself, because the resolution depends on the **highest recorded temperature at the Guarulhos station**, not a city average or a later daily summary.
