Official forecasts for Istanbul on June 5 point to a daily maximum near 26–28 °C under early-summer conditions, with moderate northerly flow, partly cloudy skies, and peak solar radiation around midday. Ensemble model guidance shows limited spread, reflecting typical June climatology where highs average 25–27 °C. Minor variations in cloud timing, boundary-layer mixing, or localized sea-breeze effects can easily differentiate outcomes between 26 °C and 27 °C. With leading probabilities nearly even, traders are pricing residual uncertainty in the final observed peak before resolution.
