Recent ensemble forecasts from major models position 27–28°C as the most probable maximum temperature for Istanbul on August 21 under typical late-summer Mediterranean conditions, with Black Sea surface temperatures near 25°C and moderate northerly flow limiting daytime warming. Historical August averages hover around 29°C, yet current guidance from sources such as the Turkish Meteorological Service and ECMWF runs indicates slightly suppressed highs due to persistent onshore breezes and limited insolation. Trader consensus reflected in the 50.5% implied probability for 27°C aligns with these stable short-range projections two days ahead, while the modest shares for 28°C and 26°C capture residual uncertainty from potential model adjustments or local urban heat effects before resolution.
