Recent forecasts from multiple meteorological sources indicate Istanbul's minimum temperature on August 26 will likely settle near 20–22°C under persistent high pressure, northeasterly winds, and clear skies that promote efficient nighttime radiational cooling. This aligns with late-August climatology where average lows hover around 21°C, with current model consensus showing minimal precipitation risk and stable subsidence limiting cloud development that could otherwise raise the overnight minimum. The near-even market-implied odds between 20°C and 25°C reflect traders balancing these guidance runs against potential small shifts in wind speed, humidity, or urban heat island effects across monitoring stations, while lower-probability outcomes below 18°C or above 27°C remain inconsistent with observed trends and ensemble spreads. Updated model runs ahead of resolution will clarify any deviations from the current trajectory.
