Latest meteorological forecasts from regional models and the Turkish Meteorological Service indicate a daytime high near 22–24°C for Ankara on September 27, driven by a stable northerly flow and increasing cloud cover that limits daytime heating. This places the outcome squarely between the market’s 17°C-or-below and 27°C-or-higher brackets, where near-even implied probabilities reflect model uncertainty in exact peak timing and any scattered showers. Late-September climatology shows mean highs declining from 26–27°C early in the month toward 23°C, consistent with the current trajectory and the influence of cooling continental air masses. Key variables for final resolution include the precise evolution of cloud cover and boundary-layer mixing on the day, with updated short-range guidance expected to narrow the range ahead of market close.
