Highest temperature in Tokyo on July 28?

Platform comparison

Market context

Tokyo's summer heat peaks in late July, with daily highs typically ranging between 32–35°C during the season. The 28th falls within the core of the rainy season's tail end, when atmospheric moisture and urban heat-island effects combine to elevate temperatures across the metropolitan area. Haneda Airport Station, located on reclaimed land near Tokyo Bay, experiences slightly different thermal patterns than central Tokyo due to maritime influence, though it remains subject to the same synoptic weather systems driving the broader region.

Historical records from Haneda show that temperatures exceeding 37°C on any single day in late July occur roughly once per decade, whilst readings above 39°C are exceptionally rare. The Japan Meteorological Agency's 30-year climate normals place the average high for late July at 33.1°C. The current 0% crowd probability suggests traders are pricing in a narrow outcome band, likely reflecting confidence in mid-range forecasts rather than extreme heat scenarios. Comparable years—such as 2019, when Tokyo recorded 37.3°C on 23 July—provide reference points for how often the upper thresholds materialise.

The settlement window closes at midday on 28 July 2026, capturing the full diurnal cycle.

Deposit friction via Klarna and SEPA rails affects book depth during the final 48 hours, when late-entry traders may face withdrawal delays if settlement occurs during weekend banking hours.
