Current ensemble forecasts from GFS and ECMWF models, aggregated by services like TimeandDate, project a high temperature of around 24°C (75°F) in Istanbul on May 16, up from 17°C the prior day, driven by a shift to high-pressure ridging and mostly sunny skies following recent drizzle. This mild warming aligns with Istanbul's Mediterranean climate, where mid-May averages hover at 21°C based on long-term observations from the official Florya station, with sea breezes from the Bosphorus often capping peaks. The Turkish State Meteorological Service (MGM) 5-day outlook supports this consensus, though 48-hour updates could adjust for cloud cover or northerly winds. Trader sentiment reflects this stability, with low precipitation risk (20%) and historical rarity of extremes this early in spring. Watch MGM briefings tomorrow for refined guidance ahead of resolution via airport measurements.
