**Official meteorological observations from Ankara's primary weather station at Esenboga Airport recorded a daily maximum of 19°C on September 23, 2026, with hourly readings peaking at that level during the afternoon before declining into the evening.** This aligns with regional model consensus and surface analyses showing stable high pressure, light westerly winds, and limited cloud cover that prevented further warming or significant cooling anomalies. Trader consensus at 100% implied probability for 19°C reflects the finality of verified station data near the close of the observation window, consistent with historical September maxima around 20–22°C but tempered by the day's specific synoptic conditions. Only an unlikely post-hoc revision from the Turkish State Meteorological Service or use of an alternate station could alter the outcome.
