Recent forecast models, including Open-Meteo and GFS runs, converged on a daily maximum near 23°C for Istanbul on October 12 under mostly cloudy skies, light northerly winds, and minimal precipitation, aligning closely with observed afternoon readings in the low 20s Celsius at stations such as Ataturk Airport. This places the outcome slightly above the mid-October climatological average of roughly 20–21°C while remaining well within typical variability for the region. With resolution imminent, final official measurements will determine exact alignment; deviations remain possible only from localized urban heat effects or precise timing of the peak, though current data strongly support the market consensus.
