Trader consensus on Polymarket implies a highest temperature near 15°C for Istanbul on April 6, with 15°C (31.5%) narrowly leading closely bunched 14–17°C outcomes (23–21.5%), underscoring short-range forecast uncertainty from divergent ECMWF and GFS ensemble spreads. Primary differentiators include the precise timing of a weak upper-level trough over the eastern Mediterranean, which could suppress daytime heating via cloud cover or light precipitation versus clearer skies allowing peaks closer to 17°C; Black Sea-influenced cool northerly flows and Marmara Sea moderation keep outcomes anchored to seasonal norms of 14–16°C early April highs. Turkish State Meteorological Service (MGM) guidance aligns with this range, but new 12z model runs and hourly updates through April 5 may resolve discrepancies ahead of measurement at official stations.
