Trader consensus on Polymarket closely splits between 18°C (24.5%) and 19°C (23%) for Tokyo's lowest temperature on May 18, reflecting genuine uncertainty in Japan Meteorological Agency short-range forecasts and global model ensembles like GFS and ECMWF, which cluster overnight lows around 17-20°C amid a mild warming trend. Recent nights saw minima near 16-17°C under clearer skies, but anticipated southerly winds (10-14 mph) and high cloud cover on May 18 are expected to limit radiative cooling after daytime highs of 26-28°C, potentially preserving shallower inversion layers. AccuWeather guidance points to 20°C, but JMA climatology for mid-May (average 16-18°C) and model spread differentiate the leaders. Watch JMA's May 16 update for refined guidance.
