Recent ensemble forecasts from the European Centre for Medium-Range Weather Forecasts and GFS models indicate Istanbul’s May 19 high will likely fall between 20–22 °C, aligning with the market’s tight clustering around those outcomes. Mid-May conditions feature moderate southerly flow across the Sea of Marmara, where sea-surface temperatures near 17 °C limit rapid daytime warming while light winds and variable cloud cover introduce small uncertainties in peak heating. This setup matches climatological norms for the period, when average highs reach approximately 21 °C, keeping probabilities for extremes below 5 percent. Traders are therefore focused on the narrow window between slight model spread and subtle changes in afternoon insolation expected in the next 48 hours.
