Recent forecasts from global and regional models indicate Istanbul's May 18 maximum will likely settle near the seasonal climatological average of 20–22°C, with ensemble guidance showing limited day-to-day variability under typical springtime synoptic patterns. Subtle differences among leading outcomes stem from uncertainties in daytime heating: stronger southerly flow from Anatolia can advect warmer continental air, while enhanced sea-breeze circulation off the Marmara Sea or increased cloud cover may cap the peak by 1–2°C. Official observations from stations such as Istanbul Atatürk Airport, combined with updated short-range runs from the European Centre for Medium-Range Weather Forecasts and NOAA’s Global Forecast System, continue to tighten the expected range around 20–21°C without signaling significant departures from historical mid-May norms.
