Japan Meteorological Agency (JMA) forecasts a high of 17°C for Tokyo on April 2 under cloudy skies with intermittent rain and 50% precipitation chance, as of the March 30 update, driving trader consensus toward mid-teens outcomes while favoring 19°C or higher at 34.4% implied probability due to potential southerly flow ahead of a passing front. The fragmented probabilities—14°C (22%), 15°C (21.5%), and others—mirror inherent short-range forecast uncertainty (reliability grade C), influenced by cloud cover suppressing daytime heating, jet stream positioning, and model disagreements on frontal timing. Historical early April highs average 16–18°C amid cherry blossom warmth, but recent mild patterns could shift with tomorrow's refined JMA guidance and ensemble model runs.
