Latest numerical weather prediction models from the European Centre for Medium-Range Weather Forecasts indicate a daytime high near 20–21 °C for Ankara on 17 May, driven by moderate southerly flow across the central Anatolian plateau and variable cloud cover that limits peak solar heating. Historical mid-May climatology shows average highs of 21–23 °C at 890 m elevation, with day-to-day spreads of several degrees common under continental air masses. Trader consensus favoring 19 °C (38.5 %) and 20 °C (30.5 %) reflects uncertainty in exact cloud timing and boundary-layer mixing, which can shift realized maxima by 1–2 °C. Updated model runs and surface observations through the evening of 16 May will refine resolution criteria before the daily maximum is recorded at official stations.
