Latest ensemble forecasts from major models position a minimum temperature near 21–25°C as the most probable outcome for Istanbul on August 26, driven by persistent high pressure, northeasterly flow off the Black Sea, and clear skies that limit overnight radiative cooling. Historical climatology shows late-August overnight lows averaging 20–22°C, with current runs indicating slightly above-average values due to reduced marine influence and daytime heat retention. Model spread creates the observed market clustering around these thresholds, while probabilities below 18°C or above 26°C remain minimal given stable synoptic conditions and no incoming fronts. Updated model guidance expected overnight will refine the exact minimum before resolution.
