Recent short-range forecasts from agencies such as the Turkish State Meteorological Service and ECMWF indicate Istanbul’s August 16 maximum will likely center near the mid-August climatological average of 27–29 °C. Stable high pressure combined with moderate northerly flow and sea-surface temperatures in the Marmara and Black Seas are expected to sustain sea-breeze moderation that limits daytime heating and keeps the distribution tightly clustered around 26–28 °C. Model consensus shows little spread, with only minor variations tied to possible increases in afternoon cloud cover or slight shifts in wind direction. Updated runs closer to the date will refine the exact peak, particularly regarding any transient ridging that could allow brief warming above 30 °C.
