Current forecast guidance from the Japan Meteorological Agency indicates cloudy skies with scattered showers over Tokyo on June 3, which limits solar heating and supports a daily maximum temperature centered on 21°C. Model consensus aligns closely on these conditions, consistent with early June climatology where average highs reach about 26°C but recent atmospheric patterns favor cooler, more stable readings near the lower end of the seasonal range. Trader consensus at 100% for 21°C reflects this tight agreement on observational data and short-term model runs. Modest uncertainty persists around exact timing of any cloud breaks or localized rainfall intensity, factors that could allow the high to edge toward 22–23°C if insolation increases unexpectedly before resolution.
