The latest Japan Meteorological Agency (JMA) short-term forecasts and ensemble models project Tokyo's highest temperature on April 4 at around 17°C, under partly cloudy skies with southerly winds around 20-30 km/h, driving trader consensus with 17°C at 39.5% implied probability and 18°C close behind at 25.5%. This positioning reflects early April climatology, where historical highs average 16-19°C at the official JMA Tokyo station, amid a warmer-than-normal spring fueled by persistent high-pressure systems and a mild winter—evidenced by JMA's April 2 cherry blossom forecast showing significantly earlier blooming due to elevated temperatures. Inherent forecast uncertainty persists from cloud cover variations and urban heat effects, with final JMA updates expected overnight and observations resolving via peak hourly readings tomorrow.
