Late August conditions in Istanbul typically feature moderate nocturnal cooling under the influence of the surrounding seas and urban heat island effects, with historical minimums averaging near 20–22°C. Trader sentiment clusters tightly around 22–24°C because current ensemble forecasts from major models show subtle differences in cloud cover, boundary-layer humidity, and low-level wind speeds that will determine how much radiative cooling occurs overnight on the 24th–25th. Clearer skies and lighter winds favor the lower end of that range by enhancing longwave heat loss, while increased moisture or a weak warm-air advection could hold temperatures near 24°C. The spread in market-implied probabilities reflects these small but decisive meteorological variables rather than any single dominant driver.
