Trader consensus heavily favors 27°C as the highest temperature in Istanbul on August 21, reflecting converging forecasts from the Turkish State Meteorological Service, Met Office, and global models under stable high pressure, light northeast winds, and partly cloudy skies that limit peak heating. Daytime maxima are projected near 28–29°C but with observational data and recent model runs pointing to a recorded high at or below 27°C at official stations, consistent with climatological August norms of 27–30°C. Dew points around 19–21°C and minimal cloud cover further constrain intensification, while any late-day clearing or wind shifts could nudge readings toward 28°C. Market-implied probabilities incorporate these variables ahead of final official verification.
