Recent forecast consensus from Turkish Meteorological Service and international models points to a 19°C daytime high in Ankara on September 29, driven by widespread thunderstorms and showers that limit solar heating and suppress temperatures after cooler conditions on the 28th. These unstable atmospheric patterns, with elevated humidity and cloud cover, align with the market's leading 40% implied probability for 19°C and 26% for 18°C, reflecting historical late-September variability in the region. Traders appear to weigh the narrow window for any late clearing that could push readings toward 20–21°C against the stronger likelihood of sustained precipitation keeping maxima at or below the forecast value.
