Japan Meteorological Agency (JMA) forecasts and global ensemble models like ECMWF and GFS project Tokyo's highest temperature on April 4 at around 17°C under partly cloudy skies with light winds, driving trader consensus with 38% implied probability on 17°C, followed by 18°C at 23% and 16°C at 16%. This aligns with early April climatology, where daily highs typically rise from 15–18°C amid spring warming from migratory anticyclones, though urban heat island effects in Tokyo can add 1–2°C. Yesterday's mild conditions around 17°C support continuity, but inherent model uncertainty from cloud cover or frontal passages could shift outcomes by 1–2°C. Watch JMA's midday update for refined guidance ahead of resolution based on official Tokyo observations.
