Trader consensus on Polymarket heavily favors Istanbul highs of 12–14°C on April 18, reflecting ensemble forecast uncertainty from global models like ECMWF and GFS, where means hover around 13–15°C amid divergent cloud cover projections. Official Turkish State Meteorological Service (MGM) guidance shows a 17°C max with min 11°C, while AccuWeather implies 16°C under partly cloudy skies and yr.no (ECMWF-based) pegs 14°C with persistent overcast. Key differentiators include northerly winds advecting cool Black Sea air, suppressing peaks below seasonal norms (historical April average ~15°C), versus potential afternoon sea breeze or clearing lifting to 14–15°C; recent mid-April trends below normal, with 00z model updates and MGM briefings tomorrow poised to shift implied probabilities.
