Recent ensemble forecasts from the European Centre for Medium-Range Weather Forecasts and Global Forecast System converge on a daytime maximum of 21–22 °C for Istanbul on May 18, reflecting the market’s tight clustering around those outcomes. Mid-May climatology recorded by the Turkish State Meteorological Service places average highs in the 20–22 °C range, with limited day-to-day variability driven by stable springtime pressure patterns over the Marmara region. Minor differences between 21 °C and 22 °C hinge on afternoon cloud cover, boundary-layer mixing, and light southerly flow that can add or subtract a degree. Final resolution rests on official station observations, which typically finalize within 24 hours of the daily maximum.
