Official forecasts from the Turkish State Meteorological Service and converging runs of the ECMWF and GFS models place Istanbul’s maximum temperature for June 5 at exactly 22°C, driving the near-certain market-implied probability. Stable atmospheric conditions, light winds, and moderate humidity are limiting daytime heating, consistent with recent observations near 20–21°C and climatological norms for early June in the region. The tight ensemble spread leaves little room for significant deviation, though a stronger-than-expected sea breeze or delayed cloud cover could push readings marginally higher; traders are monitoring the final hourly updates and airport station data for confirmation ahead of market resolution.
