**Trader consensus assigns 100% implied probability to a high of 20°C or higher in Mexico City today, backed by Servicio Meteorológico Nacional (SMN) forecasts projecting peaks of 28–30°C amid a persistent heatwave affecting central Mexico.** Recent SMN bulletins confirm ongoing dry, sunny conditions with high pressure dominating, consistent with April climatology where average highs reach 26°C at Benito Juárez International Airport—the market's resolution site—and historical April maxima rarely dip below 20°C due to the city's 2,240-meter elevation and dry-season stability. International models from AccuWeather and NOAA align, showing no cooling signals. Realistic challenges include unexpected afternoon cloud cover or rare cold front intrusion, though low wind shear and clear skies make sub-20°C highs improbable; final airport observations will resolve by midnight.
