Latest meteorological forecasts from major global and regional models project a daily high near 29°C (84°F) for Istanbul on June 3 under mostly sunny skies and light southerly flow, driving the near-100% market-implied probability for the 28°C-or-higher outcome. This aligns with early-June climatology, when average highs reach 25–26°C but warm anomalies of several degrees commonly occur with stable high-pressure patterns. Official resolution will use the highest temperature recorded at Istanbul Airport by the Turkish State Meteorological Service. Only a substantial shift in steering flow or increased cloud cover could realistically keep the peak below 28°C, though current model consensus shows low likelihood of such changes before peak heating.
