Recent forecasts from ensemble models including ECMWF and GFS point to a daily maximum in Istanbul around 25–27°C on June 16, 2026, as a warming trend replaces earlier cool northerly flow with milder conditions and greater solar heating. This aligns closely with mid-June climatology, where average highs reach 25–26°C, though model spread on cloud cover, boundary-layer mixing, and exact wind direction creates uncertainty that keeps the 25°C, 26°C, and 27°C outcomes tightly bunched in trader pricing. Official guidance from the Turkish State Meteorological Service and updated runs ahead of the 48-hour mark will further refine the peak reading, which resolves on verified observations rather than any single model projection.
