Recent Japan Meteorological Agency guidance, reinforced by afternoon observations at the official Otemachi station, shows a stable high-pressure ridge delivering southerly warm advection and strong solar heating that has locked in a maximum of 28°C for Tokyo on May 17. This positions the market-implied odds for 28°C at 99.4% as a clear reflection of converging model runs and real-time surface data rather than speculation. Historical May climatology places typical highs between 22–24°C, so the current setup sits modestly above average yet well short of thresholds for 29°C or higher. Only an unexpected late-day surge in insolation or a shift in steering flow could push readings to 29°C, scenarios the latest soundings and short-range forecasts assign low probability before evening cooling begins.
