Official meteorological observations from Ankara stations, including Esenboga Airport, recorded a daily maximum of 16°C on September 29 amid overcast skies, light rain, and light variable winds that limited daytime warming. This aligns with late-September climatology for the region, where typical highs fall between 15–18°C under similar synoptic patterns of Atlantic moisture and northerly flow. The market's near-certain consensus on 16°C reflects real-time station data confirming the peak occurred during afternoon hours without exceeding that threshold. A shift in resolution criteria or discrepancies between reporting stations could theoretically alter the outcome, though such revisions remain rare once hourly records are finalized.
