Recent forecasts from multiple models indicate a cooler-than-average day for Istanbul on July 25, 2026, with highs most likely in the 22–24°C range, driven by increased cloud cover, scattered showers, and a northerly flow suppressing the typical late-July peak. Seasonal baselines show afternoon maxima near 28–30°C under clear, stable high pressure, but current guidance highlights a transient Atlantic or Black Sea influence introducing moisture and moderating temperatures. This aligns with the market-implied probabilities favoring 23°C (42.5%) and 22°C (31%), while probabilities for 25°C+ remain low due to limited warming potential before the system departs. Updated model runs in the next 24–48 hours will refine exact maxima and any land-sea breeze effects.
