Recent meteorological data from Brazilian monitoring agencies show atmospheric conditions over Sao Paulo on May 17 produced a daily maximum temperature near the 22°C mark, anchoring the dominant market-implied probability at 56.6% for that outcome. Late-autumn patterns in the region typically feature cooler southerly flow and reduced insolation, limiting peaks to the low-20s Celsius range absent strong high-pressure warming. With the 23°C-or-higher resolution priced at only 0.3%, traders have priced in stable pressure gradients and consistent model guidance showing no significant heat advection. Official station readings will soon finalize the exact peak for market settlement.
