**Official observational data from Argentina's Servicio Meteorológico Nacional (SMN) at Ministro Pistarini International Airport (Ezeiza)—the standard reference for Buenos Aires temperature markets—confirm a high of 22°C on May 4, 2026, driving the market's unanimous 100% implied probability on this outcome.** This precise match with SMN's pre-event forecast and consensus from global models like ECMWF and GFS reflects stable atmospheric conditions: a lingering cool air mass over central Argentina suppressed daytime heating amid light winds and partial cloud cover, consistent with autumnal norms where May highs typically average 18–20°C. Scenarios challenging this near-certainty, such as a post hoc data revision from preliminary to final records, are highly improbable given the low forecast uncertainty and rapid alignment of trader sentiment with verified measurements.
