Trader consensus favors 23°C at 37% implied probability, closely trailed by 24°C (29%) and 22°C (20%), reflecting Japan Meteorological Agency (JMA) forecast models projecting highs in the low-to-mid 20s°C for Tokyo on May 3 amid persistent above-normal spring temperatures across eastern Asia. Recent two-week outlooks from JMA, updated within the past day, show a high-pressure ridge promoting sunny conditions and mild advection of warmer air, with ensemble means centering near 23°C based on historical early May averages of 21-22°C elevated by neutral ENSO conditions leaning toward emerging El Niño influences. Differentiating factors include potential afternoon sea-breeze moderation or cloud development capping peaks at 22°C versus sustained solar heating pushing to 24°C; watch JMA's evening update and Haneda Airport observations for resolution-defining max temperature.
