Current numerical weather prediction ensembles from ECMWF and GFS project a daytime maximum near 26–27°C in Istanbul on August 14 under stable high pressure, light northerly flow, and mostly clear skies with low humidity. This consensus, updated within the past 48 hours, drives the market’s heavy weighting toward 26°C while keeping 25°C and 27°C as viable alternatives given typical ensemble spread of 1–2°C. Seasonal baselines place August averages around 27–28°C, yet the near-term pattern shows no heat-wave amplification or cloud-cover reduction that would push readings higher. Traders monitor the next model cycles and official station data from Istanbul Airport for any last-minute adjustments before resolution.
