Japan Meteorological Agency forecasts indicate a high of 21°C for Tokyo on April 16 under cloudy conditions with occasional rain and 50% precipitation probability, driving trader consensus toward this outcome at 32% implied odds, closely followed by 20°C and 22°C. Recent observations align with mild mid-spring patterns, including a 21°C high projected for April 15 amid stable high-pressure influences, while two-week outlooks note "very high" temperatures above seasonal norms of 18–20°C. High uncertainty stems from variable cloud cover potentially suppressing peaks below 20°C or allowing brief clearing to push toward 23°C+; urban heat island effects at official JMA stations and evening showers add volatility. Resolution hinges on verified maximums from Tokyo observatories, with updates possible before midnight JST.
