Trader consensus assigns a 100% implied probability to a highest temperature of 28°C in São Paulo on April 19, 2026, anchored by official observations from the São Paulo-Guarulhos International Airport meteorological station, the market's designated resolution source per Instituto Nacional de Meteorologia (INMET) protocols. A persistent mass of dry subtropical air suppressed cloud cover in the afternoon, allowing surface heating to peak at 28°C despite pre-event INMET forecasts of 26–27°C under partly cloudy conditions with low humidity around 50%. This aligns with historical April climatology for the region, where airport readings often exceed city averages by 1–2°C due to urban heat effects and exposure. Scenarios challenging this near-certainty—such as data revisions from extended observations or instrument recalibration—are exceedingly rare, as INMET finalizes daily maxima within 24 hours using standardized World Meteorological Organization guidelines.
