Official observations from Benito Juárez International Airport, the market's resolution station, already show temperatures surpassing 19°C this morning, with current readings around 22°C under mostly sunny skies as of early afternoon on May 15. Forecasts from Mexico's Servicio Meteorológico Nacional (SMN) and international models like those on AccuWeather project today's high near 26–30°C, driven by May's dry season climatology—averaging 25°C highs at Mexico City's 2,240-meter elevation—and absent cold fronts or cloud cover to suppress heating. Trader consensus at 100% implied probability reflects this near-certainty, backed by real-time METAR data and diurnal solar warming patterns. Only an unprecedented mid-day cold snap could challenge it, though no such indicators exist in current atmospheric conditions. Final high reports expected by evening.
