Short-range forecasts from the Turkish State Meteorological Service and ECMWF place Istanbul’s August 15 maximum between 25–28 °C, aligning with mid-August climatology of 27–29 °C highs and positioning 26 °C as the market leader at 60.5 % implied probability. Typical late-summer steering patterns, moderate northerly winds, partial cloud cover, and sea-breeze moderation from the Bosphorus and Black Sea limit daytime heating and reduce the likelihood of extremes above 27 °C or below 25 °C. These factors underpin the tight clustering of trader consensus on 25–27 °C outcomes while assigning minimal weight to outliers, with final verification expected within hours of local sunset on the resolution day.
