Highest temperature in Tokyo on August 10?

Platform comparison

Market context

Tokyo’s highest temperature on 10 August will be set by the peak reading in Weather Underground’s Daily Observations table at Tokyo Haneda Airport Station, not the summary high/low figure. Tokyo’s August climate is typically hot and humid: historical August averages cluster around 31°C to 32°C highs, and recent August records have included days in the mid-30s Celsius, so the market is about *where within the usual summer range* the day’s top observation lands rather than whether it becomes warm at all.[5][13][14]

A 0% YES crowd price implies the market is treating the outcome as effectively unavailable or very unlikely at this stage, but the historical frame argues against reading that as a climate signal. Comparable August data for Tokyo show frequent highs around 30°C to 35°C, with occasional hotter spikes, and even recent daily histories have placed midday temperatures in the mid-20s to upper-20s Celsius before the afternoon maximum is set.[3][4][9] For accessibility, “no-KYC up to $1,500” usually means a user can trade up to that notional amount without identity verification, while larger limits or withdrawals typically trigger KYC checks; that affects participation friction, not the weather outcome itself.

The main catalysts are ordinary meteorology rather than policy events: the day’s temperature path, cloud cover, sea breeze, rainfall, and the timing of any local convective showers will determine whether the afternoon peak gets capped early or climbs later. Market participants should watch the station’s intraday observations through the settlement window and any nearby forecast updates from major weather services, as Tokyo’s August maxima often move materially between late morning and mid-afternoon.[2][8][11] From a regulatory angle, German GlüStV restrictions can affect whether a resident can legally access or market this kind of event contract, while US CFTC reach matters because event-based derivatives may be treated differently under US commodities rules depending on the platform’s structure and user location.

Is Polymarket legal in my country?
