Recent numerical weather prediction consensus from models such as GFS and ECMWF indicates Istanbul will experience mostly sunny conditions on August 26 under moderate northeasterly flow, supporting a daily maximum near 29–30 °C at official stations, though traders appear to favor slightly cooler readings around 27–28 °C. Persistent Etesian winds off the Black Sea and a post-heatwave cooling trend have lowered afternoon temperatures from recent peaks near 32 °C, while clear skies and light winds limit convective mixing and keep the thermal profile stable. Low precipitation probability and seasonal insolation decline further constrain upside potential, with any model run-to-run shifts in boundary-layer moisture or wind speed serving as the next key variables ahead of final observational data.
