Recent forecasts from multiple models indicate Istanbul's September 1 minimum temperature will likely fall in the 19–22°C range under typical late-summer high-pressure conditions and light northerly winds, aligning with climatological averages near 18–20°C. With the event only 48 hours away, limited model spread and absence of incoming fronts or unusual moisture support steady overnight radiative cooling without sharp drops or spikes. Trader balance between sub-16°C and 26°C+ outcomes reflects ongoing uncertainty in exact boundary-layer mixing and urban heat-island effects rather than any observed anomaly, while narrower buckets around 17–25°C capture the most probable central tendency. Updated ensemble runs and local observations in the final 24 hours will clarify whether modest deviations from guidance materialize.
