Recent forecasts from multiple meteorological sources indicate highs of 29–32°C for Istanbul on August 25 under mostly sunny conditions with moderate northeasterly winds, consistent with late-summer patterns where average maxima hover near 28–30°C. Trader consensus favoring 27–28°C reflects expectations of slight cooling from current 30–31°C readings, possibly due to persistent sea breezes or minor model adjustments in GFS and ECMWF runs. With resolution hinging on official station maxima and no significant heat advection or cloud cover projected, these outcomes align with stable atmospheric conditions rather than anomalous warmth. Updated short-range guidance ahead of the date could refine probabilities.
