Official meteorological observations from São Paulo stations recorded a daily maximum of 22°C on June 13, 2026, aligning with seasonal June averages of 21–23°C under typical wintertime conditions influenced by cooler Atlantic air masses and frontal passages. This outcome reflects verified surface data rather than model projections, with market-implied odds at 100% underscoring trader consensus on the post-event resolution. Minor uncertainty could arise only from rare station calibration discrepancies or definitional disputes over the precise maximum, though such revisions remain statistically improbable given consistent regional reporting.
