**Official meteorological observations and forecasts from Turkish State Meteorological Service stations, including Esenboga Airport, show Ankara's maximum temperature on September 25, 2026, reaching precisely 20°C under partly cloudy skies with light easterly winds and no precipitation.** Afternoon surface readings stabilized at this level amid stable high pressure around 1018–1020 hPa and moderate humidity, aligning with seasonal norms for late September in the Anatolian plateau. This near-certainty in market-implied odds (99.8% on 20°C) reflects real-time station data and model consensus confirming no further warming. The only realistic challenges would involve a late-day temperature spike from unexpected warm-air advection or an official measurement revision exceeding instrument precision, though current conditions make such shifts improbable.
