Recent JMA forecasts and seasonal outlooks position 32–33°C as the leading outcomes for Tokyo’s July 15 maximum, reflecting typical mid-July conditions under mostly cloudy skies with limited daytime heating. Above-normal summer temperatures are expected across Japan per the agency’s June–August guidance, consistent with climatological averages near 30–32°C and recent model consensus showing highs of 31–35°C. Short-term factors include moderate humidity, light winds, and partial cloud cover that cap extreme peaks, while the absence of typhoon influences or clear-sky radiative heating keeps probabilities for 34°C+ below 5%. Updated model runs and JMA briefings over the next 48 hours remain the key variables that could shift trader-implied odds within this narrow range.
