Latest ensemble forecasts from the European Centre for Medium-Range Weather Forecasts and Global Forecast System point to a daytime maximum near 21–22 °C in Istanbul on May 18, keeping the 21 °C and 22 °C outcomes tightly matched in trader pricing. Mid-May climatology for the region, drawn from Turkish State Meteorological Service records, places average highs at 20–22 °C, so current model consensus sits squarely within historical norms rather than signaling an outlier. Small differences in predicted cloud cover, sea-breeze timing along the Bosphorus, and subtle steering of a weak high-pressure ridge over the Marmara Sea create the narrow spread between these two leading bins. Forecasters will release updated model runs overnight, which could shift the implied probabilities if any late adjustment to wind direction or boundary-layer moisture appears.
