Numerical weather prediction ensembles currently position 27–28°C as the most probable daily maximum for Istanbul on August 22 under typical late-summer Mediterranean conditions. Sea-surface temperatures near 25°C and moderate northerly flow limit further warming, while the absence of strong downslope or föhn effects keeps the upper tail narrow. Recent model runs show high consistency across the 26–29°C window, aligning with climatological baselines where August highs average 28–30°C. Trader consensus, reflected in the combined 79.5% implied probability for 27–28°C, incorporates this forecast stability while assigning low odds to 30°C or higher given the narrow uncertainty range and stable synoptic pattern ahead of peak heating. Updated guidance from agencies such as the Turkish State Meteorological Service will determine any late adjustments.
