Trader consensus for Tokyo's peak temperature on May 17 centers on forecast uncertainty between a typical spring high and brief early-summer warmth, with models showing 29–30 °C as the most probable range. The Japan Meteorological Agency's latest ensemble runs place the city under a strengthening subtropical high, where daytime heating and light southerly flow support maxima near those thresholds. Mid-May climatology averages 23–25 °C, yet recent Pacific sea-surface temperature anomalies and reduced cloud cover have lifted guidance by several degrees. Resolution hinges on the exact timing of any sea-breeze onset or frontal passage, factors that could still shift the peak by 1–2 °C. Updated model cycles and observational data expected within the next 24 hours will narrow the remaining spread.
