Trader consensus around 26–28°C for Istanbul’s August 20 high reflects tight forecast uncertainty just 48 hours out, with models showing modest spread in peak values. Typical late-summer conditions feature highs near 28°C moderated by Bosphorus and Marmara Sea breezes, yet subtle shifts in northerly flow versus transient high pressure can push readings 2–3°C higher or lower. Recent ECMWF and GFS runs indicate limited moisture and generally clear skies, but small timing differences in any weak frontal passage introduce the observed clustering; historical August extremes rarely exceed 32°C without strong regional heat advection. Updated model guidance expected within the next 24 hours will likely narrow the distribution ahead of resolution.
