Official observations from Brazil's Instituto Nacional de Meteorologia (INMET) confirm a maximum temperature of 30°C at key São Paulo stations on April 18, driving trader consensus to 100% market-implied probability for that outcome as the definitive resolution data. This aligns with prevailing dry autumn conditions under subtropical high pressure, where numerical weather prediction models like those from CPTEC/INPE had forecasted highs near 30°C in the days prior, with minimal convective activity to push temperatures higher. While daily maxima measurements carry high reliability from calibrated sensors, rare post hoc revisions during quality control or discrepancies across secondary stations (e.g., Congonhas vs. Guarulhos airports) could theoretically alter positioning, though no such issues have surfaced in initial reports.
