Forecast models from sources like the Turkish State Meteorological Service and international ensembles indicate partly cloudy conditions over Ankara on September 27 with light northerly winds and dew points supporting overnight radiative cooling to the low-to-mid teens Celsius. This places the expected minimum near 12–15°C, creating balanced market-implied odds between sub-9°C and 18°C+ outcomes amid typical ensemble spread in short-range guidance. Ankara’s high-plateau location amplifies sensitivity to cloud cover and wind shifts, while historical September climatology shows average lows near 14°C. Updated model runs and local observations through the weekend will refine the precise threshold before resolution.
