Recent forecasts from the Japan Meteorological Agency and models indicate mostly cloudy conditions with scattered showers possible on August 31, limiting daytime heating and supporting highs near 29–30°C. Persistent easterly flow and residual moisture from a stalled front have kept recent daily maxima suppressed below seasonal averages around 30–31°C. Key variables include afternoon cloud thickness, which reduces insolation, and any convective development that could cap temperatures further or allow brief clearing for a spike toward 31°C. With multiple ensemble runs clustered in this narrow range and no strong high-pressure ridge building overhead, trader consensus reflects the narrow spread between these outcomes amid typical late-summer variability.
