Latest numerical weather prediction models from agencies including the Turkish State Meteorological Service and ECMWF consensus favor a daily maximum of 27–28°C in Istanbul on August 21, driven by persistent high-pressure ridging, clear skies, and light northerly flow moderating the urban heat island effect under typical late-summer Mediterranean conditions. Sea-surface temperatures around 25°C in the Bosphorus and Sea of Marmara limit further warming, while historical August climatology shows average highs near 29°C with day-to-day variability of ±2–3°C. Recent model runs have tightened the distribution around these values, though afternoon sea-breeze timing and localized convection could still shift the exact peak by 1°C before resolution.
