Latest ensemble runs from ECMWF, GFS, and Turkish State Meteorological Service models converge on a 20–22 °C peak at Istanbul Airport on May 18 under weak high-pressure ridging, placing the market’s leading 20 °C and 21 °C outcomes in a tight 57 % consensus. Mid-May climatology supports this range with an average high near 21 °C, while the Bosphorus sea breeze and lingering marine air moderate afternoon heating. Slight model spread arises from uncertain cloud cover and boundary-layer mixing; clearer skies could briefly push readings to 23 °C, whereas increased low stratus would cap the maximum at 19 °C. Updated short-range guidance and surface observations through May 17 evening will refine the final distribution before resolution.
