Current forecast models from sources including the Met Office and Open-Meteo consensus point to a minimum temperature in Istanbul on October 10 in the 15–18 °C range under clear to mostly sunny skies and light southerly flow. This stems from a stable high-pressure pattern with warm-air advection and limited nocturnal cooling, keeping the overnight low well above seasonal norms near 12 °C. Model spread in boundary-layer mixing and exact wind speeds creates the tight market split between outcomes above 20 °C and 10 °C or below, while specific bins around 11–18 °C reflect uncertainty in radiational cooling rates. Updated runs from the European Centre for Medium-Range Weather Forecasts and local Turkish Meteorological Service observations expected overnight will refine the precise minimum before resolution.
