Short-term ensemble forecasts from global models such as ECMWF and GFS indicate a stable high-pressure ridge over the eastern Mediterranean, supporting daily maximum temperatures in Istanbul near 27–28°C on June 25, with limited cloud cover and light northerly flow moderating the urban heat island effect. Recent model runs show tight clustering around these values, though small differences in boundary-layer moisture or timing of any weak trough could shift the peak by 1°C. Historical June climatology places average highs near 26–27°C, providing context for why trader-implied probabilities concentrate on outcomes between 26°C and 28°C rather than extremes. Updated 48-hour forecasts and local observations from the Turkish State Meteorological Service remain the key near-term catalysts.
