The Japan Meteorological Agency's latest forecast, updated April 13, projects a high of 21°C in Tokyo on April 15 under cloudy skies with a 60% chance of scattered showers, driving trader consensus toward 20–22°C outcomes amid above-normal spring temperatures (seasonal average ~20°C). Recent warmth—24°C on April 13 and 23°C forecast for April 14—reflects a high-pressure ridge yielding to incoming moist air, potentially capping peaks via reduced solar insolation, though lighter precipitation could allow 22°C. Model ensembles show slight spread due to cloud variability and southerly flows; daily JMA updates and April 14 observations will refine implied probabilities as resolution nears.
